UMA GT Jersey S11

Assos UMA GT Jersey S11

The Assos UMA GT Jersey S11 is the lightest and most breathable UMA GT jersey from the brand – made for long rides when it gets really hot in Switzerland. The body uses ultra-light AirCell fabrics for maximum air circulation and quick drying, while the raw-edge, friction-free sleeves provide a clean, aerodynamic finish. Compared to the UMA GT C2 EVO, it's around 25% lighter while maintaining comfort in a regularFit cut. The torso offers UPF 15, which is why Assos recommends applying sunscreen underneath; the sleeves provide additional protection and support thanks to their material choice. We have the UMA GT Jersey S11 available in two variants.

• Ultra-light AirCell main fabric with open hexagon pattern for strong cooling and rapid moisture wicking.
• Push Pull sleeves with raw-cut finish for friction-free fit, aerodynamic lines and UPF 50+ on the arms.
• Triple Ramp Pockets with flexible "lids": extra elastic at the top for more storage space, stabilized at the bottom to prevent sagging.
• PILtec Plug-In hem gripper with micro-dot silicone: stays secure and stable even when wet.
• regularFit with set-in sleeves for plenty of freedom of movement and stable shoulder areas.
• Torso with UPF 15 – designed for high summer rides; sun protection underneath recommended.
• Back pockets additionally supported by Stabilizer V11 mesh for cooler, more breathable performance.

Technical Details and Features

The heart of the jersey is AirCell, an ultra-light circular knit with open hexagon pattern that allows air to circulate very freely and feels almost like a Racing Series jersey. Its Bi-Stretch properties provide horizontal conforming stretch while offering vertical support, keeping the jersey stable when loaded. The Push Pull sleeves embrace the muscles comfortably and keep weight low, while the raw-cut finish eliminates transition edges. At the back, Stabilizer V11 stabilizes the pocket system, keeping contents secure while maintaining high ventilation. The PILtec Plug-In hem gripper at the back prevents shifting – even when it gets damp. The torso fabric is so light and cooling (UPF 15) that Assos clearly recommends sunscreen underneath.

Applications and Benefits

The UMA GT Jersey S11 shows its strengths on long summer rides – from flat evening loops around Lake Zurich to alpine passes like the Albula or Susten. When temperatures rise, you benefit from the noticeable cooling performance and dry wearing feel, without sacrificing an everyday-suitable, not-too-tight regularFit cut. For a cohesive setup, combine the jersey in Summer 1/3 Layering with a light Skin Layer P1 and the UMA GT Bib Shorts C2. The set-in sleeves give you full freedom of movement when climbing and a stable shoulder area on long descents. In short: A versatile women's road cycling jersey that performs reliably in the Swiss summer – whether on solo rides, marathons or group training sessions.

Optional: Fit and Usage Tips

The regularFit is close to the body but not racing-tight – ideal if you appreciate comfort on longer distances while still wanting a sleek silhouette. Choose your size so the jersey fits smoothly in cycling position (in drop bar position); the raw-cut sleeves should gently embrace the upper arms without cutting in. If you're planning very sunny days, use the UPF 50+ sleeves for protection and wear additional sunscreen on the torso due to UPF 15. For layering in high summer, the jersey harmonizes with the Summer Skin Layer P1 base layers, which further boost moisture transport. This keeps your setup light, airy and functional – just right for hot Swiss summer days.
