ASSOS Size Chart

All measurements are body measurements in cm / inches. ASSOS is cut for the riding position, so it can feel tight standing up. We recommend sizing up one full size for a more relaxed fit.

Men’s Jerseys / Jackets / Vests

Measure around the fullest part of your chest, then factor in height. Use waist as a third reference.

The MILLE GT LS Jersey S11 EVO is a lightweight long-sleeve jersey for daily cycling with extended UPF protection. It evolves the GT platform with an even lighter, more breathable construction and a simplified — yet still ample and secure — pocket system.

Long sleeves in lightweight, highly breathable Eclipse textile add sun protection with UPF 50+ from shoulder to wrist. The AirCell body textile is an ultralight circular knit with an open hexagon pattern for cooling airflow and moisture management. The simplified pocket construction keeps the cargo-securing ramp design with cleaner lines and fewer seams. The Stabilizer V11 back panel helps reduce pocket sag when loaded. Available here in Golden Yellow and Deep Petrol.
