Nathan 18oz Insulated Soft Flask with Bite Top

Product Details
Style: NS4017

The Nathan 18oz Insulated Soft Flask with Bite Top is a mouthful of a name, but it's designed to make it easy for you to get mouthfuls of cool refreshment on any run - and the name tells you everything you need to know. It's insulated, allowing it to keep beverages cool 38% longer than uninsulated competition, and it's a soft flask that makes it easy to pull as much hydration through the Bite Top valve as you need. That soft flask design also means it's easier to pack away as you drink more, but a rigid frame design keeps it from getting floppy and difficult to handle.
