UMA GT Winter Jacket

Assos UMA GT Winter Jacket

The Assos UMA GT Winter Jacket is a winter-ready road-bike jacket for female riders who want to train outdoors in cold, changeable conditions. Its two-layer material concept combines protection and breathability so you stay reliably warm in late autumn and through the winter without overheating. The front uses NEOS Medium to protect your core, while NEOS Light and RX on the arms, forearms and back provide targeted ventilation and freedom of movement. The regularFit cut with raglan sleeves is optimized for the riding position and leaves room for layering. Practical for everyday use: the secure Triple Ramp Pockets and the easy-glide front zipper for quick temperature control. These features make the jacket a strong choice for Swiss conditions between Lake Zurich fog and Jura-Bise.

• NEOS Medium front: 3-layer softshell with PU membrane, 100 % windproof and water-repellent
• NEOS Light on exposed zones for reduced weight and increased breathability
• RX fleece material on forearms and back for warmth and moisture management
• regularFit for comfortable layering on long rides
• Raglan sleeves for unrestricted shoulder movement on the road bike
• Triple Ramp Pockets and full-length zipper for secure nutrition storage and easy ventilation

Technical Details and Features

The front of the UMA GT Winter Jacket relies on NEOS Medium, an in-house 3-layer softshell with a PU membrane that effectively shields the core area from wind and spray. NEOS Light is used on the upper arms to reduce insulation slightly and increase breathability, while the fleece-lined RX on the forearms and lower back prevents overheating. The sporty-relaxed regularFit feels streamlined but offers enough room for a Winter Skin Layer or a midlayer. Raglan sleeves eliminate traditional shoulder seams and maximize freedom of movement; the Full-Length Zipper with locking feature makes climate control easier. At the back, the Triple Ramp Pockets with elastic "flaps" keep tools, gels and your phone stable and within reach; material composition is 47 % polyamide, 35 % polyester and 18 % elastane. Independent tests of the related UMA GT Winter Jacket Evo highlight high windproofing, very good breathability and low pack volume — exactly the strengths that stem from the NEOS/RX combination.

Use Cases and Benefits

Whether daily commuting in the city of Zurich, base sessions on the Mittelland or fast laps around Lake Zurich: this jacket covers a wide winter temperature range when you layer it smartly. In calm phases NEOS keeps the wind out, while RX moves moisture away once intervals start or climbs get hard. The regularFit lets you add a warmer Skin Layer under the jacket in bise conditions without compromising mobility. The Triple Ramp Pockets keep bars, pump and gloves organised, and the zipper helps with rapid temperature changes, for example after a pass descent. Assos recommends combining it in the GT system with Winter Skin Layer and UMA GT Winter Bib Tights — a sensible complement for long winter blocks in Switzerland.
