Don\'t simply keep your drink cool, keep it cold. Constructed from the highest quality materials, Patriot Canteens preserve ice for up to 24 hours or keep beverages hot for up to 6 hours. The cupholder-friendly design and wide mouth make the Patriot Canteen ready for any adventure. Patriot Coolers proudly supports our Veterans. With every purchase, a donation is made to Homes For Our Troops.
