Quench your thirst when on the go by adding the Sports Cap to your order of Envirosax Aqua Skinny water bottles. The Sports Cap replaces the screw top that the bottles come with and provides a spouted mouthpiece that opens and closes with a simple quarter turn. It also has a dome protective lid to keep the mouthpiece clean. Perfect for exercising, playing sport or just when you're on the go! Also perfect for school kids as it is so much easier to use for little ones – not to mention less likely to get lost!!
