Assos Uma GT Wind Vest S11 Info
The Assos Uma GT Wind Vest S11 is built for the rides where the wind is the problem and the temperature could go either way — the vest covers the range from 53°F on a cool morning to warmer conditions where you just need to cut the headwind. It's part of the women's Endurance series, and the S11 generation brings a meaningful upgrade over its predecessor: the back panel now matches the front.
Both the front and back are covered in Buster, a close-knit woven textile rated 5/5 for windproofing with an Eco DWR finish that sheds light rain and road spray. Previous versions used a mesh back that left the rider exposed to wind from behind — the S11 closes that gap entirely. Side panels of Sens Air (75% polyamide / 25% elastane) add stretch and breathability in the less-exposed areas where you need to move freely, keeping the vest from feeling like a shell. The result is a vest that blocks wind in a complete wrap around the torso without sacrificing the mobility a rider needs in the saddle.
The double slide zipper runs two sliders independently — crack it from the bottom to vent during hard climbs, open just enough from the top to reach a jersey pocket underneath, or adjust both for precise temperature management. The main Buster fabric is 100% polyamide, and Assos has updated it to pack down smaller than the previous generation, making it realistic to carry in a jersey back pocket as backup when you're not sure the weather will hold. Regular fit layers cleanly over a base layer or jersey without bunching.

Design Benefits
- Full front-and-back Buster coverage — the S11's key upgrade over the previous generation: windproof protection extends across the entire back panel, not just the front.
- Sens Air side panels — elastic and breathable where you need to move, keeping the vest comfortable across a wide effort range without overheating.
- Double slide zipper — two-slider construction lets you vent from the bottom, access jersey pockets, or dial in coverage without fully unzipping.
- Improved packability — updated Buster textile packs to a smaller volume than the previous generation, making it a practical jersey-pocket carry.
Final Take
The Uma GT Wind Vest S11 is a well-considered piece of kit for riders who face variable conditions regularly — not just a cool-morning layer, but a vest that earns its place across a genuinely wide temperature range. The full Buster back is the upgrade that matters most, and the packability means it goes with you on rides where it might not be needed, just in case.
