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

Nice product but not for me

Products nice, it's just a little to loose for my balgene bottle for me. Great quality but misses the mark. I gave 4 stars due to being an innovative and quality product, but minus 1 star as it doesn't fit my needs and I probably won't use.

I need more!

This is a great addition to a Nalgene! Biggest issue is… I have a small collection of Nalgene so now I need more cap straps!

Cap Strap

For Christmas I got my fiancé a custom Nalgene bottle and I had seen some ads on insta from this company for the cap strap and thought it would be a perfect duo gift. We do a lot of hiking and he was thrilled he’s now able to clip his bottle anywhere rather than carrying a separate sling or stuffing it in his back pack. I’ll be buying myself one as well !

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.

What is your return policy?

We have a 30-day return policy, which means you have 30 days after receiving your item to request a return.

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.
