Soft Flask 500ml – Lightweight, BPA-Free TPU Collapsible Bottle for Hiking & Trail Running
Carrying a standard bottle while hiking or running can be a hassle—they are heavy, bulky, and awkward to store. The 500ml Soft Flask solves this: made from safe, food-grade TPU, it weighs just 33 grams and collapses when empty. Its 500ml capacity is perfect for quick hydration, and its flexible design makes it easy to stow in a pouch, backpack, or running vest.
