GSI Outdoors Flask - 18 oz. Reviews:


Cool flask

A previous entry said that they didn't know if it was BPA free or not. I ordered it anyways, because I like GSI products. And lo and behold! When I looked at the label, it definitely says BPA free. So yes it is for any of you wondering out there. Good product from GSI as usual! :)

Lighter than a metal flask

This is the only light lexan flask I've found. I tried a cheap plastic flask which leaked and a metal one that was heavier and carried only 8oz. My friend has used this flask on back-country trips for 2 years, so it seems to be pretty durable.

Perfect for alcohol - Stove or Folks

Purchased to tote fuel for alcohol stove on long trips as well as personal internal warmth as needed. Well built, lightweight, sturdy. Good value.
