Built as a versatile add-on for hydration vests, packs, and compression belts, the Tapered Soft Flask 14oz features a tapered shape that contours comfortably in front vest pockets. The classic bite valve gives you control over flow so liquids go where you want them.

Compatible with all Nathan hydration vests, packs, and wide compression belts, it's a go-to choice for marathon, trail, and ultra runners.
