Take handheld hydration to the next level of comfort and efficiency with this grip-free, ergonomic soft flask. The patented ExoSpine means the soft flask feels natural in your hand, even as the fluid level decreases.
Works great with Nathan vests, as the durable spine allows you to easily store the soft flask in front pockets. It’s so comfortable, you’ll probably forget that you’re holding it.
