capCAP+ is 100% BPA-free, polycarbonate-free, and phthalate-free. Both caps are made with FDA-approved, food-safe polypropylene (#5) plastic.
New capCAP+ has a few additional cool features like the "CapKeeper" that holds the small cap out of the way when drinking and rubberized grips on the small cap.
Drink spill-free through the small spout, and then clean and fill easily with the large cap. Don't forget that the wide, rounded strap is more comfortable to hold too.
capCAP is the civilized 2-in-1 accessory cap designed to work with Nalgene, CamelBak, and most other popular wide-mouth drinking bottles. The new, re-designed capCAP+ is also compatible with Hydro Flask wide-mouth, Nalgene Stainless, and Guyot Stainless.
