Humangear CapCap


  • capCAP is the civilized 2-in-1 accessory cap for Nalgene, CamelBak, and other popular wide-mouth drink bottles.

    Most wide-mouth bottles are easy to fill and clean, but the standard opening is too big to drink from easily without spilling. Narrow-mouth bottles are great to drink from but you can forget about putting ice cubes in them, let alone cleaning them. And bottle inserts don't really fix a spout that was never meant for daily drinking.

    capCAP offers the best of both worlds. Drink spill-free through the small spout, and then clean and fill easily with the large cap. The rubberized small cap is easy to grip, even with gloves on. Don't forget that the wide, rounded strap is more comfortable to hold too.

    capCAP is 100% BPA-free, Polycarbonate-free, and phthalate-free. Both caps are made with FDA-approved, food-safe polypropylene (#5) plastic. It is also covered by humangear's lifetime warranty.

    • Opening Size: 2.5" (63mm)
    • Dry Weight: 1.4 oz. (39.7g)
    • Cleaning: Dishwasher-safe (top rack only)

  • capCAP works with most popular BPA-free 63mm wide-mouth bottles including:

    The capCAP is not guaranteed to work with Klean Kanteen wide mouth bottles; capCAPs may work on some Klean Kanteen bottles and may leak on others.
