Replacement 28mm Tethered Cap

Love the replaceable customizable options

Theses are decent, don't overtighten, caps will bust

These fit perfectly on smart water bottles so I don’t lose my cap on the trail or at camp. I use with the one bottle hydration system. Durable products. Thanks!!!

I love this product! Having a tethered cap for your smart bottles ensures you won’t lose it, and reduces the chances of leaving trash behind when you’re out in the wild.

I've been rocking these caps for a couple of years where they see moderate weekly use in every season. I add them to all my 1 liter bottles to add that little bit of security when traveling over backcountry talus, boulder and snow fields where a little white cap is easily dropped only to become unrecoverable or blown away to oblivion.

Despite the love I have for theses caps they can split at the top from heavy use and/or over tightening. Something I have never experienced with regular caps in 35+ years of backcountry travel and climbing. Because of this, I still carry a spare original 1 liter bottle cap.
