The Zefal SENSE PRO 80 water bottle has been designed to the smallest details so it would provide the best possible support to the cyclists. Similar to the Sense and Shark bottles, the Zefal SENSE PRO 80 is made of lightweight, soft polypropylene that will keep your drink clean and odourless. It comes with a special cap shape for easy holding. It is 100% impermeable thanks to the Lock-Cap-System with a double closure. The silicone mouth piece provides a pleasant sensation in the mouth. The quick-opening valve provides better-regulated control of the liquid.
