A Better Bottle Cap
by Humangear

The capCAP+ makes using a widemouth water bottle even better. An ergonomic spout allows you to drink spill-free, with a rubberized cap that is easy to grip even with gloves on. The widemouth base works great with most widemouth popular wide-mouth bottles including Nalgene, Hyrodflask and CamelBak. Check the Compatibility Chart to see a complete list. A flexible strap keeps the two caps tethered while drinking. The new CapKeeper holds the small top cap back when you drink. This combination of features allows you to clean, fill, drink from, and carry your bottle with ease.

  1. Not sure if anywhere else sells these, I’ve only bought them from Widefoot and I will continue to come back. Great product and fast turnaround/shipping!
    The hinge can get worn and torn over time, but this is still my favorite aftermarket mouthpiece for nalgenes.

  2. Makes the bottles much more functional

  3. Great cap!

  4. Amazing how something so simple can change so much. Awesome cap, solid seal on Hydroflask and Nalgene.

  5. With this bad boy, I can enjoy more water in my mouth, and less on my clothes
