Full Description

Design & Action

Boiling water on a blistering summer ride or a frozen solid bladder on a snowy trail kills your hydration when you need it most. The VST Bladder Sleeve 3.0L is an insulated hydration bladder sleeve engineered for riders who refuse to let extreme weather dictate their water supply. This thermal hydration bladder sleeve wraps your USWE 3-liter bladder in protective insulation that regulates temperature in punishing heat and sub-zero cold without turning your pack into a bulky mess.

Tech & Specs

  • Insulated construction: Shields your hydration reservoir from temperature swings in scorching deserts or frozen alpine trails
  • 3-liter capacity: Fits USWE 3L bladders perfectly for all-day hydration on extended rides and runs
  • 43g weight: Adds barely noticeable protection without loading you down on climbs or long distances
  • VST harness compatible: Integrates seamlessly with USWE VST Mesh, Small Size, Standard, and Termocell Winter harnesses for quick setup

Fit & Kit

Slide your USWE 3L bladder into the sleeve and drop it into your compatible VST daypack. The sleeve works with VST Mesh Harness, VST Small Size Harness, Standard Harness, and VST Termocell Winter Harness systems for versatile year-round use. Clean the exterior with a damp cloth and let it air dry between rides to keep the insulation performing at peak efficiency in hot weather or cold weather conditions.

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 9 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!

VST Bladder sleeve 3,0L

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.
