An innovative soft-sided hydration option, the Nathan ExoShot Flask (12 oz) can function as a minimalist handheld bottle or stow conveniently in the pocket of a running vest.
The flask has flexibility and packability that you won’t find in a traditional water bottle. An integrated “spine” gives the bottle just enough structural support to allow it to hold shape as the water level decreases so it isn’t unruly when you’re drinking. A locking cap has in integrated bite valve so you get leakproof performance but a high flow rate when you need it.
- Locking cap and bite valve keep liquid from escaping
- Patented ExoSpine provides structure to soft flask
- Fits all Nathan race vest pockets
