The capCAP was humangear's first product, and its popularity has increased every year since we launched it in 2008. Now, after 10 years on the market, weve gone back to the drawing board in order to add more compatibility and functionality with stainless steel wide-mouth bottles.

The capCAP is not only compatible with more bottles than the original capCAP, but it also has some great new features like the CapKeeper that holds the small cap back when you drink and rubberized grips on the small cap that make it easier to twist open.

The capCAP is 100% BPA-free, polycarbonate-free, and phthalate-free, and both caps are made with FDA-approved, food-safe polypropylene (#5) plastic. Both small and large cap gaskets are made from food-safe silicone.
