Warmth without weight and bulk is what every traveller needs, but when you need your arms free for activity and your body toasty warm, the Vigilante Richter down vest for Men is the way to go. Crafted from a durable DWR nylon shell and filled with a 550 power loft, it will warm you to the core but keep you on the move. Best of all, it packs neatly into its very own travel pillow for warmth and convenience in one!
Aldi had some lightweight down jackets when I was there yesterday both hooded and non-hooded for $39.99 & were very similar quality to my Kathmandu heli jacket maybe even slightly thicker (I have to old 500 fill version so might be similar to the newer 600 ones) not vests like this but might be of use to someone, I don't think it was posted and to late to post now I think as it'll be hit and miss as to whether your store has stock. I was honestly surprised by the quality for $40.
