The Salomon Soft Flask 400mL/13oz Insulated 42mm now has dual-skin insulation with a sleek new design to keep your fluids in liquid form in the winter or stay cold during the summer. Thanks to its convenient bite valve lid, you can keep the nozzle protected from dirty trails and avoid ice build-up while also being able to quickly take a drink when needed. As an added benefit, the 42mm opening allows for easy filling and cleaning, while a clip around the lid can attach to the outside of a pack or be used as a handle.
