I want a drink bottle thats suitable for protein shakes which is close to unbreakable. Forget anything plastic unless it's notable for being very tough. It doesn't have to be a protein shaker perse but it must have large lid so it can be washed without a bottle washer and it must seal - I don't need the silly mixing stuff that shakers have.
Reason is I'm sick of protein shakers breaking in my bag for obvious reasons … plastic shakers break if they recieve regular shocks like being dropped a short distance inside a bag. Thin metal ones with plastic lids don't break but they warp so the lid no longer seals.
Any recommendations?
Haven't seen any "tough" shakers - they all seem to be made of the same type of plastic. Thinking it might be easier to learn to just place your bag down gently rather than throw it down onto the floor.
My bag gets tossed around and thrown as well, but my shaker has never broken because of that.
The only time my shaker breaks is if I keep screwing the lid on too tightly all the time - the thread bit eventually cracks.
