Size chart: Assos size chart for the Equipe RS Jersey S11 (scroll to Size & Fit on that page). Click on "What's my size?" next to the Assos sizes to use their fit calculator.
The Islington race jersey, cut for going fast.
RS is Assos's race pattern and uses their top-tier fabrics: an open 3D knit through the body, a compressive warp-knit on the sleeves and a silicone-gripper hem that stays put. Close everywhere, long in the sleeve, short at the front. If you race, do chaingangs, or just like a tight jersey, pick this one.
Full zip, 3 rear pockets.
Sizes XS to 2XL. Assos sizing, and the RS runs smaller than the GT. The retail equivalent is the Equipe RS Jersey S11; see Size & Fit on that page.
You can visit the Assos store on Regent Street to try sizes before you order.
Pre-order. Ships late February 2027.
The final manufactured design may be slightly modified, e.g. logo placement.
