Zefal Bottle Arctica Pro 55

The Arctica Pro insulated bottle keeps your drink at the right temperature until 2.5 hours. The overmolded cap provides better gripping of the bottle, and the double-closure system makes it 100% waterproof for easy transport. The silicone push provides a pleasant feeling in the mouth, and the quick-release valve allows you to control the liquid consumed, evenly and without overflow.
