The Vapur .5L Anti-Bottle($10) stands when full and folds when empty - easily fitting into pockets, purses or packs. "Made from an internal layer of polyethythene covered with two layers of nylon, the Vapur “anti-bottle” also ships with a carabiner for hanging from bags, just like those aluminum SIG bottles. The bags can be frozen, can carry boiling water and will even stay open when dishwasher-ed." |
