Castelli Puro 4 Long-Sleeve Jersey Dark Grey, Size XS.

Made for fine, cool days, the Puro 4 Jersey is warmer than its weight would suggest, reflective for grey days or in case your ride runs long, and stretchy enough to offer a close and flattering fit, without ever feeling restrictive. It's also very good at wicking sweat. The 180g fabric punches above its weight due to its 3D knit, which traps air inside and warms it as you ride. It is still breathable enough to manage moisture with aplomb, though, while high stretch ensures it's very comfortable to wear. Features A good looking, long sleeve jersey for early autumn or late spring rides in fine weather. Offers mid-weight warmth, 3D fabric traps air close to the skin. Made from 93% polyester, 7% elastane for a close but not tight fit. Manages moisture well. With reflective panels on shoulder, heat transfers on pocket to boost visibility. 3 x rear pockets and gripper elastic at waist. Weighs 284g. For temperatures of 12-18°C.
