18oz Soft Flask w/Bite Top

Product Information

This 18oz soft flask from Nathan is an excellent choice for staying hydrated on the move, whether you're hitting the trails or logging road miles. Its flexible design collapses as you drink, minimizing sloshing and allowing it to stow away easily once empty. The integrated ExoSpine provides crucial structural support, making it comfortable to hold and simple to slide into and out of hydration vest pockets.

The reliable bite valve delivers a high flow of liquid with minimal effort, and it's designed to be leak-free, so your hydration stays where you want it. This flask is perfectly compatible with all Nathan hydration vests, making it a versatile addition to your running or hiking kit.
