UMA GT Winter Jacket EVO

Assos UMA GT Winter Jacket EVO

The Assos UMA GT Winter Jacket EVO is a streamlined women's winter jacket in regularFit, designed for rides in cold conditions and optimized for the forward-leaning position on road bikes. The front features NEOS Medium, a three-layer softshell with PU membrane that Assos claims is highly breathable, waterproof and 100% windproof. NEOS Light is used on the upper arms, while RX Fleece on the back and forearms stores warmth and rapidly wicks moisture to prevent overheating on long rides. The jacket is part of the GT 3/3 Outfit System and pairs ideally with Winter Skin Layer and GT Winter Bib Tights; the material composition is 51% polyamide, 30% polyester and 19% elastane.

• Front panel in NEOS Medium (3L Softshell) with PU membrane for weather protection
• Upper arm sections in NEOS Light for reduced weight and enhanced breathability
• Back and forearm zones in RX Fleece for targeted insulation and moisture management
• Women-specific regularFit with raglan sleeves for unrestricted movement in the saddle
• Three Triple Ramp Pockets with "lid" inserts, 2W waistWave waist construction and reflective details
• Part of the Assos GT 3/3 Layering System; ideal when combined with Winter Skin Layer
• Officially specified features and material mix for Swiss winter conditions and everyday rides

Technical Details and Functions

Assos strategically positions the textiles according to airflow and riding position: NEOS Medium on the front panel shields the torso, while NEOS Light on the upper arms reduces weight and increases ventilation. Under the arms and on the back, RX as a fleece-backed knit fabric regulates the microclimate, which is crucial during intervals, climbs or headwinds. The Triple Ramp Pockets stabilize pocket contents with flexible inserts, while 2W waistWave maintains stretch at the waist and reduces bunching. One-piece front with raglan sleeves ensures a clean fit and great freedom of movement, reflective accents increase visibility at dusk. All these elements are officially specified by Assos for the UMA GT Winter Jacket EVO and designed as a system.

Applications and Benefits

This jacket excels on road bikes and for commuting in Switzerland – from damp, cold morning rides around Lake Zurich to windy hills in the Mittelland. In independent tests, the UMA GT Winter Jacket EVO was praised for its blend of wind protection, water resistance, insulation and breathability; it carries you comfortably through autumn into winter without unnecessary bulk. The back section with RX zones helps with thermal management, while the front provides reliable protection even in wet, cold Bise conditions. In heavy, persistent rain, the back can become somewhat damp over time, confirming the construction's focus on front protection. For very harsh cold, the jacket can be extended with an Ultraz Winter Skin Layer to shift the operating range downward.

Fit, Sizing and System Setup

The regularFit cut is form-fitting and designed for base layer + jacket, which makes aerodynamic and thermal sense. Test reports indicate that the jacket runs rather slim; those who prefer to wear additional mid-layers underneath or want lots of freedom of movement should consider this when choosing size. Three generous rear pockets allow food and phone to be stored securely without contents bouncing, which is especially practical on longer winter rides. For a cohesive setup, combine the jacket with Assos Winter Skin Layer and UMA GT Winter Bib Tights to fully exploit the GT 3/3 concept. The close-to-body fit improves moisture wicking and prevents cooling on descents.

Quality and Support

Assos backs the UMA GT Winter Jacket EVO with a 2-year warranty and a crash policy, which additionally secures the product's longevity. The precise panel construction and proprietary NEOS/RX textiles are designed for many winter seasons when care and layering are done sensibly. Thanks to the robust yet lightweight materials, the jacket remains dimensionally stable and comfortable to wear even after frequent use. For Swiss conditions, this means: reliable protection in everyday use and on training rides, without unnecessary weight or rustling.
