The Salomon Soft Flask 400ml is ready for year-round adventures thanks to its dual-skin insulation that prevents your water from freezing in the winter and keeps it cold in the summer. Whether you’re running, hiking or ski touring, the new bite valve evacuates ice build-up with a quick squeeze while the grippy handle makes it easy to drink on the move. This flask’s soft, flexible shape is ideal for storing in your pocket, and it shrinks as you drink to limit sloshing. Details: High-flow valve Large 42 mm opening.
