What Our Gearhead(R) Experts Are Saying: "Simple, fast, and zero slosh. This Soft Flask 500ml slips into a vest pocket, the thermo-moulded base drops in cleanly, and the high-flow valve makes quick work at aid stations. As it empties it compresses, so there's less bounce and more comfort on the run."We reach for the Soft Flask 500ml Water Bottle from Salomon when we want quick, no-fuss hydration on the move. Salomon's shrink-as-you-drink design cuts bounce as the flask empties, while a thermo-moulded bottom slides easily into belts or vest pockets. The high-flow valve keeps sips smooth mid-stride, and the flexible build packs down small when the miles stack up.
