Built for runners who want a leak-proof soft flask for vest pockets, the QuickStart Soft Flask 14oz features a push-pull locking bite valve that shuts off when you're not drinking — ideal for transport, training, or stashing in a pack between sips. Fits perfectly in any Nathan hydration pack or vest flask pocket. The 42mm opening makes filling and cleaning easy, and the soft, conforming material carries comfortably in any pocket. Show more
