Endurance Elevated: Inside the New ASSOS MILLE/UMA GT S11 Collection
- New MILLE/UMA GT S11 range refines comfort, breathability and fit
- Modernised aesthetics with a newly updated ASSOS logo and a refreshed spectrum of colourways
- Racing Series technology trickled down into an updated S11 design
February 2nd 2026 – Stabio, Switzerland — ASSOS of Switzerland, the performance cycling apparel brand, today launches the latest evolution of its endurance cornerstone, the MILLE/UMA GT S11. Designed for daily riding, season after season, the new jersey and bib shorts refine comfort, breathability, and fit while modernising aesthetics across the collection.
As the core of ASSOS’ endurance range, the S11 generation builds on its legacy with material updates, trickled-down Racing Series technology, a cleaner, more contemporary silhouette, and an updated ASSOS logo.
MILLE/UMA GT Jersey S11 EVO
The MILLE/UMA GT Jersey S11 EVO is engineered to keep riders cool, dry, and comfortable for daily riding. The main body retains ASSOS’s proven AirCell textile, an ultralight circular knit with an open hexagon structure that delivers exceptional airflow and elasticity.
The sleeves are updated with Eclipse, an impossibly light warp-knit material with an ultrasoft feel and UPF 50+ protection. Borrowed from the Racing Series, the raw-cut sleeve construction creates a low-profile finish that improves aerodynamics while eliminating pressure points.
The Triple Ramp Pockets use flexible panels to help stabilise cargo even when fully loaded. Available in a refreshed spectrum of colourways, including Black, White, Edge Green, Blossom Pink, Golden Yellow, Ground Brown and Deep Petrol in the Mille Range. The UMA range is available in White, Almond Milk, Edge Green, Blossom Pink, Wisteria Violet and Golden Yellow.
“The MILLE/UMA GT is the backbone of our collection, so every update has to meaningfully improve the ride experience,” says Luca Zanasca, Senior Manager of Development at ASSOS of Switzerland. “For S11, we focused on refining the essentials: increased breathability, and subtle construction improvements that deliver noticeable gains in comfort, stability, and fit - ride after ride.”
MILLE/UMA GT Bib Shorts S11
The MILLE/UMA GT Bib Shorts S11 refine everyday comfort with a lighter, more durable construction and a longer leg length for a modern silhouette. The new QUARTZ textile delivers breathable compression with permanent odorControl, making it a perfect choice for those long days in the saddle, with 80% of the fabric content made from pre-consumer recycled polyamide.
Stability and support are enhanced through rollBar bib strap technology, adapted from the Racing Series to lock the insert in place as the rider moves through sprints, climbs, and corners. At the leg openings, the PILtec Plug-In grip provides a secure hold in wet or dry conditions with an invisible, low-profile finish.
At the core of the shorts is the GT S11 Insert, featuring a 12mm endurance platform with Shock-Absorb Damping Mono foam, a three-layered perforated construction for increased breathability, and the goldenGate 2.0 technology that allows the insert to move freely with the body, reducing friction throughout the pedal stroke.
The GT S11 shorts are lighter, more durable and have a deeper, true-black colour that remains opaque under stretch. Other colourways include Moss Green and Burgundy Red in both ranges.
The MILLE/UMA GT S11 Kit continues to define what everyday cycling apparel should feel like: refined, reliable, and uncompromising in comfort. Designed for riders who demand performance without distraction, it is endurance equipment at its most evolved.
