FAQ

Does this sleeve work with non-USWE hydration bladders? +
It's designed specifically for USWE 3L bladders and VST harness systems. Other brands might fit, but we can't guarantee the same locked-in performance.
How much does the insulation actually help in extreme heat? +
The thermal layer keeps your water noticeably cooler on scorching rides by blocking direct sun and heat transfer. You won't be drinking hot soup mid-trail.
Can I use this sleeve in freezing temperatures for winter riding? +
Absolutely. The insulation works both ways, preventing your water from freezing solid during cold weather rides and runs.
Will this sleeve fit inside my existing USWE pack? +
It's compatible with VST Mesh, Small Size, Standard, and Termocell Winter harnesses. Check your pack's harness type to confirm compatibility.
How do I clean the bladder sleeve after muddy rides? +
Wipe down the exterior with a damp cloth and let it air dry completely. Don't machine wash it or you'll trash the insulation.

Customer Reviews

Overall rating: 4.6 / 5 from 10 reviews.

It keeps water cold for a few hours even in Texas heat. Granted i put my water in the fridge the night before i riding and add sufficient amount of ice. Totally worth the money in my opinion.

It really does help keep my drinks cool even in the Texas heat!

I live and ride in Miami Florida. It’s very hot here to say the least. This thermo bag works amazing. 3 rides in and my water has never gotten close to room temperature. This thing works perfectly. It does make my 3L bag (2L bladder) a bit more full and rounded but totally worth it. 💯 recommended.

Got the product but did not have a chance to try it yet. Will tell you in the middle of August.
