UMA GT LS Jersey

Assos UMA GT LS Jersey

The Assos UMA GT LS Jersey is the long-sleeved summer jersey for female riders who want to stay cool while tackling long rides on hot, sunny days. Developed in the S11 generation, it combines ultralight materials with high breathability and UPF 50+ UV protection on the sleeves. The body uses airy fabrics with UPF 15, which is why Assos recommends using sunscreen underneath. Available in two variants – blackSeries and White Series – each in sizes 2XS to 2XL, so you can adjust the fit to your riding style.

• Main material AirCell with open hexagon pattern for maximum breathability, moisture wicking and cooling.
• Long-sleeved Push Pull sleeves with UPF 50+ for reliable UV protection and elastic, lightweight comfort.
• Ultralight body with UPF 15; it's recommended to apply sunscreen underneath.
• Three rear Triple Ramp Pockets with flexible "lids" keep contents secure and prevent sagging.
• Stabilizer V11 mesh supports the pockets and increases air circulation.
• Aerodynamic raw-cut sleeve finishes for clean lines without disruptive transitions.
• PILtec Plug-In hem gripper with micro-dot silicone for slip-resistant hold – even when wet.
• Comfort-oriented regularFit with set-in sleeves for free movement on long distances.

Technical Details and Features

The AirCell main material is an ultralight circular knit fabric with open hexagon mesh that provides noticeable cooling, dries quickly and feels almost like a racing jersey. Its bi-stretch properties wrap around the torso horizontally while providing vertical support to keep the jersey in shape. The sleeves are made from Push Pull, a lightweight, low-volume and highly elastic textile with UPF 50+; at the cuffs, raw-cut edges provide a smooth, aerodynamic silhouette. The three rear pockets are additionally supported by Stabilizer V11, while Triple Ramp "lids" reliably secure pocket contents; at the back, PILtec Plug-In keeps the jersey stable even in moisture. Depending on the variant, the material composition differs: blackSeries uses 43% polyamide / 41% polyester / 16% elastane, White Series 76% polyester / 15% elastane / 9% polyamide.

Applications and Benefits

This long-sleeve summer jersey shows its strengths when the sun is blazing in the lowlands, the Ticino passes are calling, or you want additional UV protection on your arms during long days in the saddle. The combination of extremely breathable AirCell body and protective Push Pull sleeves keeps body temperature controlled without the typical "heat buildup" feeling. Thanks to regularFit, the UMA GT LS sits comfortably close to the body but remains relaxed on endurance rides and moves friction-free with you. For the summer layering system, Assos recommends combining it with the Women's Summer NS Skin Layer P1 and the UMA GT Bib Shorts C2 so that ventilation and moisture management work together optimally.

Quality and Service

Assos backs the UMA GT LS Jersey with 2 years warranty and a crash policy, which additionally secures the construction designed for durability. This gives you confidence when your jersey is regularly challenged in training and on long tours. At the same time, the robust construction with PILtec Plug-In hem and stabilized pockets allows for a smooth, rattle-free ride – even with fully packed nutrition. So you get high-end performance with practical details that count just as much in everyday Swiss road riding as on alpine panoramic routes.
