Insulated Soft Flask 400ml

Escarpment Verified: Battle-tested in the winter. Ready for any weather.

The industry standard for running hydration. This 400ml soft flask features a dual-skin insulation to keep your water from freezing in the winter. With a new bite valve that clears out any ice build-up with a quick squeeze, this flask is compatible with the wide 42mm opening, making it incredibly easy to refill quickly at aid stations or drop in ice cubes on hot summer days. It shrinks as you drink to prevent bouncing and sloshing, fitting perfectly into the front pockets of any Salomon hydration vest.
