The Nathan Winter Bottle with Freeze-Free Cap reduces what freezes first with most water bottles...the nozzle and cap.

A protective flip-top cap, easily opens even with gloved hands, providing the simplest solution to the freeze-up problem. The Freeze-Free cap is designed to stay closed during activity. To prevent it from accidentally opening, the cap will only open when squeezed on both sides.

Soft, squeezable low-density polyethylene provides quick bursts or soft, even flow. Textured areas and ridges around the bottle provide a secure hold. Wide mouth design makes for easy cleaning and filing. Fits standard bike bottle cages.

22 fluid ounce capacity.
