Built as the perfect compact companion for hydration vests and packs, the Soft Flask with ExoSpine™ 14oz is a smaller-capacity soft flask designed to fit in front vest pockets or carry on its own. The classic bite valve gives you control over flow so liquids go where you want them, not down your chest.
Fully compatible with all Nathan hydration vests, this is the go-to flask for marathon, trail, and ultra runners who need a reliable add-on.
