The CAP STRAP is a metal ring that screws through the threads of your water bottle. It seats just beneath the cap and provides a material advantage in durability and security. Unlike plastic alternatives, the CAP STRAP will never stretch, making it a dependable companion for both big wall climbs and everyday commutes.

Now in available in two styles: 

  • Classic: Aluminum Ring with a Woven Strap
  • Pro: Stainless Steel Ring with a Metal Loop
    • Treat the Pro like a bolt — it will scratch the paint on your carabiners
    • The Pro is also a bottle opener

Frequently Asked Questions

Why wouldn't I use the plastic loop on my Nalgene?

To put simply - the plastic loop is not built for hanging your bottle. The plastic will stretch and break overtime, leading to lost bottles or a hazard in high exposure activities.

The Cap Strap is built for those who need a dependable alternative. It uses an aluminum ring, bar tack stitching, and 1 inch webbing so you can take your bottle with you - wherever you go.

Why does the Cap Strap not fit on the 48oz or Ultralite bottles?

The Cap Strap is designed to screw onto Nalgene and similar bottles and sit under the Cap. In order for a bottle to be compatible with the Cap Strap there needs to be some space between the Cap and the lower flange of the bottle. On the 48oz and Ultralite bottles, the gap is too narrow and the Cap Strap stops the bottle from sealing.
