Macpac Thermals: 2 for $50 or 3 for $65 (Geothermal Pants RRP $49.99) + $10 Shipping ($0 C&C/ $100 Spend) @ Macpac

890

Looks like this deal from last year is back!

Plenty of sizes left in my area, free C&C!

They seem to fit true-to-size and getting the size down was too small, necessitating an exchange. YMMV however.

Made with 100% recycled polyester, our Geothermal baselayers are light, warm and fast to dry. Soft on skin with a brushed fleece backing, they’re designed to manage moisture build up as required and dry fast when wet. A durable baselayer, Geothermals are ideal for hiking and general purpose outdoor use — available in a range of styles and seasonal colours.

100% recycled polyester fabric with brushed backing
Fabric maximises warmth and moisture management
Fast drying
Robust and durable construction
Lightweight for low volume layering
Easy care, next-to-skin fit

    Stinky plastic thermals

    • +11

      Exactly, these seem too expensive for polyester "thermals"

      • +4

        They aren't "thermals", they are thermals.

        • +3

          I had to read twice to understand that they are thermals, not "thermals". My eyes are "hurting".

      • +4

        They’re made from recycled polyester, so I assume the production cost is higher. I am usually happy to pay more to support recycling of materials for new products.

    • +13

      Have used these Macpac Geothermals on long multiday hikes in Tas.
      Never had smell problem. Just wash them!

      Put them in my bag to wear under outer clothes on overseas trips.
      Light, warm, & quick drying.

      • +6

        I haven't used the Macpac thermals but I have plenty of other poly thermals, I wear thermals most the time through Tassie winters, at home and in the bush, never had any smell issues, I really don't know where this "stinky plastic thermals" thing comes from, lol …

        Poly certainly isn't as warm as real merino but ya get what ya pay for,.,.

        • +2

          Polyprop have had that reputation for a very longtime.

          Likely from heavy physical activity, where a lot of sweat is produced. If you sweat a lot & have a BO issue - not recommended.
          Probably why I haven't had a problem in years of cold climate use😉

          These are all pretty similar to most Polyprop. I like the cut of these - fit me better.

          12 days on The Overland Track, never had a smell issue.
          Wear underwear under them (some don't), to minimise smells & sweat.

          Handy for cold cold nights. Use the oldest ones for that use.

      Is it the thermals …. or is it you?

      • +1

        Is it the thermals …. or is it you?

        Couldn't say for sure but I end up stinking pretty quick wearing synthetic base layers…can wear natural fibre for days without the stink.

        • Now there's your problem…
          Stink is a sign you're not using your gear correctly!

          Shouldn't be wearing base layers, which are designed to wick & absorb the sweat - for days!
          Just wash regularly!

          When hiking, it's something to be aware of as often in very close contact with others (sleeping crammed in huts etc). You can soon get a bad reputation!

          I've never has a stink problem - on multiday mountain hikes up to 12 days, with these Macpac polyester thermals.
          They're small & light, so I take a few, wash, & wear the next day.
          Natural fibres are slow to dry, not durable, & heavy if get wet. So I don't use those (except around city).

          These thermals are designed to be used for hiking & strenuous outdoor activity.
          Were yours?

            WTF? So plastic stinks after a few hours yet merino is fine for days and I'm not using my gear correctly.

              @OzBragain: You said you wear base layers for days…

              That's not using your gear correctly.

              Base layers against your skin - absorb your sweat. So need regular washing. Even if you don't think they smell.

              Wearing merino for days without washing is not healthy. Or it's not working well as a base layer if its not wicking & absorbing your sweat.


              Not all polyester clothes are the same.
              Years ago I sweated & stank after a few hours in a polyester shirt. It was embarrassing! Never bought another polyester shirt!
              If I based my decision on that bad polyester experience, I would not have used these thermals.

              Have you worn these thermals?
              Certainly hasn't been a problem with these Macpac & other hiking thermals for me over years. They're designed to be used in the outdoors, where things can get pretty sweaty!💦

                Not sure why you're having so much trouble understanding this but I guess it doesn't really matter. I have no problem wearing merino over multiple days and will continue doing so. Plastic stinks after a few hours so I now only wear natural fibres.

                They're designed to be used in the outdoors, where things can get pretty sweaty

                I generally only wear thermals when I know I'm going to be standing around in unpleasant conditions, if I'm getting "pretty sweaty" then I don't need thermals.

                  @OzBragain:

                  if I'm getting "pretty sweaty" then I don't need thermals.

                  Hiking up cold mountains - people usually sweat profusely. That's what these thermals are designed for. To wick & absorb that sweat. To keep your skin drier.

                  Best to know how to use your gear & what it's designed to do!

                  You won't say what polyester thermals you used. Have to assume not these, designed to wick sweat when hiking etc.

                  Stinky plastic thermals

                  You claim this brand are stinky?? On what basis? Simply that it's is made from polyester you don't like?

                  Ever worn a fleece? Or trackie dacks?
                  They're usually 100% polyester! And not specially designed to handle sweat.

                  And yet you proudly wear your thermal underwear for days without washing!! Oh boy!! Enough said!

                    Righto and here I was thinking thermals are designed to keep me warm (there's a hint in the name there champ). As I said, if I know I'll be getting hot and sweaty I won't need to wear thermals.

                    You won't say what polyester thermals you used.

                    You're right but that's because I no longer use them and have no idea what they were.

                    Fleeces are usually 100% polyester!
                    Ever worn a fleece?

                    Yes but never as a base layer (perhaps you should learn a little about layering and know your gear). On the odd occasion I do wear a fleece as a mid/outer layer when I get hot…guess what…both the plastic fleece and I stink.

                    Thank you for the banter but I can see we have different views. I'm quite happy for you to wear plastic base layers if you wish, you can trust that they don't work for me or keep pushing your point. You can have the last word…I'm done.

                      @OzBragain: If you didn't buy specialised hiking thermals, designed to wick moisture like these…

                      they’re designed to manage moisture build up as required and dry fast when wet. A durable baselayer, Geothermals are ideal for hiking…
                      Fabric maximises warmth and moisture management
                      - in Deal Description.

                      You were effectively wearing thin polyester trackie dacks as a base layer (not designed to wick & absorb moisture)!
                      No wonder you were sweaty & smelly!

                      You seem to have not even bothered to read the product description above!
                      Before assuming you know hiking thermals are only good for 1 thing… thermals are designed to keep me warm! Wrong!

                      Seems you don't understand & didn't wear hiking thermals! That is what is in this Deal!!

                      Thermals designed specially for hiking provide BOTH warmth & moisture management!


                      FLICKIT is a very experienced Tasmanian hiker. A braver person than me, just returning from 2 weeks in the bush in Northern Tas.
                      He also hasn't experienced stinky issues with polyester thermals for hiking. I think he lives in them😉

                      But you think I "should learn a little about layering and know your gear". Lol!
                      I've got years of experience wearing thermals & hiking gear! Even arranged a medivac of an injured hiker I found, when blizzard like conditions were imminent. She was unprepared & unlikely to survive.


                      You made incorrect assumptions about the product & didn't read the Deal!

                      You don't know the important difference between normal thermals & this style of thermals primarily designed for hiking.
                      That moisture wicking is vital for comfortable use. Anyone thinking they know about layering & gear should know that.

                      Seems you've never used this product. So, made an inaccurate comment that these are Stinky plastic thermals! Unfortunately supported by others who also.apparently lack knowledge of this type of specialised product.

      I can vouch the thermals don't stink. Maybe it's the person saying stinky.

    • +1

      Poly thermals serve a purpose. I prefer Merino but poly is more durable and dries quicker so I use it for my bicycle commute to work.

      • +1

        Yes, depends on your use.
        On long hikes I use Polyester - good wicking, hard wearing & fast drying. Been using it for years.
        Also take on overseas trips - light & fast drying.
        More expensive Merino for fashionable city use - looks good & feels great, but not durable. A new addition, bought very cheap on sale

        • +2

          Polys melt and are a fire hazard.
          Natural fibre does well to repel flame, embers etc but fine for exercise ( POLY's not for work; welding, cutting, grinding, electrical, chemical, heat exposure)
          Fashion aside, I would never recommend any base layer which will melt to your skin

          • @PlaunsJanus: Who wears thermal underwear as an outer layer exposed to such hazards?

            Been wearing them for so many years for hiking - near fires & camp stoves. Always safely under non-flammable layers (to keep warm). Never had an issue.

            Not an issue found in a quick search. Never seen a report of an incident.

            • @INFIDEL: Yeah, I know and agree
              But something that melts to your skin is a risk I would never take.
              It resists fire ok but will melt at a much lower temperature.
              Poly gloves will not last near anything above 200c and are fine for protection against cold but will disintegrate upon exposure to embers, hot metal, plastics.

              Poly's are great in rain and hiking but a risk I would never take camping or working

              Edit: I have purchased such outer layers for snow jackets, puffer vests like the popular Kathmandu or North face jackets

              • @PlaunsJanus: Like with any gear - use safely & appropriately. I've never done any welding, cutting, grinding in the wilderness😉

                Like you comment, most down jackets are more of a fire risk.

            • @INFIDEL: I sound a bit over cautious. I know but most dont recommend for certain things;
              (quick google is same again and again)

              Not for bedding, children etc.

              Just hiking and exercise IMHO

              • @PlaunsJanus: Will bear that in mind.
                My Eco fleece hiking overpants proudly state made from recycled plastic bottles. That would more of a fire risk🔥

                Many warm outer clothes are often made of Polyester & blends.
                Same as some sleep on polyester sheets.

                I do wear old Polyester thermals to bed - often under polyester based trackie dacks & fleece… But there are no naked flames or heating in the house, so fire risk is minimal.

      Yep plastic thermals are sweaty af

    • -1

      ABSOLUTE BS!
      You've never even worn THESE HIKING THERMALS!

      they’re designed to manage moisture build up as required - Deal Description.
      That technical design & use of different (but still polyester) fabric means a higher price.

      You wore some other clothes sold as "thermaIs", lacking the vital moisture wicking & absorption of thermals specifically designed for sweaty hiking!

      With record cold temp here, wore my Macpac Geothermal LS top & long pants against my skin for 36hr straight.
      Worn under clothes while gardening & walking up hill to shops.
      Taken multiple pairs on 12 day trekking in mountains.

      NOT STINKY!
      They control sweat & therefore smells.

      • -2

        Calm down champ

        • You're the one misleading others!

          You don't know what you claim & put in comments. You are promoting false ideas!

          Just shows popular comment badges are a joke when they mislead on facts about the Deal.

          Because you wore an item called a "thermal" - you think you know this different technical product designed for very active hiking.
          You're so wrong!

          Not reading the Deal Description, you thought it was just another "polyester thermal"… They're not!

          You didn't even know these hiking thermals control moisture, & hence smell.

          They work very well as I have experienced over multiple purchases & years of active use!!

          I've used this exact product over many long mountain hikes & never had a stink issue!

          Hiding your useless comments as they can't be trusted!
          Very wrong to mislead in Deals!!

      • As I pointed out above & in online discussions of thermals for vigorous hiking…
        It's Polypropylene thermals that have a bad reputation for stinking, not Polyester thermals! It's a different fabric!

        Merino thermals are great - I have them & love them. Probably best base layer to keep warm.
        But they also have their disadvantages (worse at moisture management - crucial in active sports, less durable, higher cost for good ones) - so aren't so good for long vigorous hiking like these.

        Simply choose the appropriate thermals for your use!

      I'm no expert but I think if you are going to buy Merino wool you should do it in a reputable way so you know what you are buying.

      It could be fake, many are blended with polyester and there's no way to know what you are buying.

      • +3

        Not trying to be critical but I was wondering the same, made in China "Merino Wool Blend" with no other details, it doesn't fill me with confidence, is it a 1% merino wool blend?

        At the price I find it hard to believe there's much merino in them…

        • +2

          Might not be the soft comfortable clothes you're looking for!

          There are different standards of pure Merino. I've had very itchy but expensive Icebreaker Merino.

          This is likely a very minimal amount of the most basic Merino in blend…
          Possibly the discards of manufacturing better quality garments

          Keep warm, FLICKIT!

          • +1

            @INFIDEL: For sleeping I find the ebay ones I linked (I have more than 10 items the same) more comfortable than most 100% merino I have from name brand vendors, they are also equally as warm and wash/dry the same as pure merino.
            I'd never consider sleeping in polyester as per the OP items here.

            • @Wolfy: Have many very old Polyester thermals, no longer good for hiking in (stretched, failing elastic). But the material is still toasty warm.
              So cost nothing. That's where they're used - to sleep in.
              Like all clothes - washed regularly. So no smell issue.

      • +1

        "could be"? This is 100% fake, no way this has over 10% of Merino for $15.

      • The packaging and product tags only mention merino wool, however as you said it could/may be blended.
        However, I have more than 10 of the above items (purchased at a retail shop) and rate them as comfortable and as warm as the pure merino I have from other brands.

    • I think the main disadvantage for these is wearing them under fitted clothing because they look much thicker than your standard thermals

  • Stocked up in Kathmandu extra 30% off clearance sale in November

    Bought with the regular $20 vouchers:
    basic thermal top & bottom were $4.50 a pair (Similar to these I also own.)

    100% merino wool LS tops were $15 & SS for $8. Look great. Very comfy & warm!

    How are these compared to Uniqlo Heattech? I just bough the Long Johns pant (19.90), will wear them to work tmr but pretty ok so far now at home.

    • +2

      I'm generally a big fan of Uniqlo. I purchased their Ultrawarm HeatTech series last year, unfortunately not that great in terms of warmth.

      • I hope mine would keep me warm enough, I dont want to feel stacked inside my jean when the thermal pant is too thick, thats why I got just the normal version.

        Do you know that there are 2 types of each Long John pants, for example:

        https://www.uniqlo.com/au/en/products/E429021-000?colorCode=…
        Body: 24% Polyester, 3 colors

        https://www.uniqlo.com/au/en/products/E441613-000?colorCode=…
        Body: 39% Polyester, 2 colors

        Same thing with extra warm and ultra warm as well.

        Not sure how much of dif between those two but I guess not that much.

        • +2

          I wear these Macpac under street clothes to the shops.
          Very thin. Not noticeable, just very warm.

          Always pack at least 1 set for overseas travels.

          Used to keep a pair in my day pack in Hobart - just in case I needed them.

          Can literally be a lifesaver if caught in the cold away from shelter!

    • Please give an update, I'd like to know how the heattech is as I'm thinking of getting them.

      • +2

        Sure, just so you know I got the 24% Polyester, standard version. I often have a long walk to my carpark either at midnight or 6am, Mel weather.

      • Pretty ok so far, Im still feeling somewhat "coolness" but the neither cold or freezing. If your job/work requires physical exercise, I think your body would be warm enough/ keep the heat in. Or you could get the extra and ultra version for the price of x2 standard, or… buy 2 and stack them : )).

    • +3

      Uniqlo for Melbourne winters is ok. Anything colder and it not warm enough.

      Macpac ones are decent for the price, took them to the snow this year and was fine. Not as warm as my Icebreaker Merinos but I’m not visiting anywhere as cold.

    • +3

      These are designed more for outdoor activities like hiking. Small, light, warm, & quick drying on long trails.

      Layer these for extra warmth. I take up to 3 pair on multiday hikes in Tasmanian mountains.

      Have used these & other brands of Polyester thermals for years in snow & ice - here & overseas.

    • I just bought these too, the 24% polyester ones. Wore them on a walk in the hills on the weekend, with only a pair of trackies over the top. 7 degrees and stayed nice and warm the whole 3 hours. Definitely can't complain.

      • It's MacPac haha, I've seen it so often and I thought if it was actually a deal it would be on here already 🤣

        • Its a fairly regular sale price.
          I've bought it cheaper.

  • it keeps showing stock in store, but everytime i try to checkout it says out of stock and asks me to choose another store…same thing happened with 3 or 4 stores nearby

  • Polyester is not a good material for thermals. It wicks water, which cools you and also stinks.

    Stick with uniqlo at this price range

    • uniqlo….. riigghtt…
