On the 11th day of Christmas, I found a Simms 32oz. Headwaters Bottle underneath my Christmas tree! This double walled, vacuum-insulated bottle will keep liquids hot for 8 hours and will keep your cold stuff cold for up to 24 hours! Since its made with premium food-grade stainless steel its dishwasher safe, and the Simms orange powder coating eliminates any bottle sweating. This sturdy bottle would make the perfect Christmas gift for the angler on your list!
