The Assos iJ.bonKa.6 jacket will soon be your versatile, 'go-to' jacket for almost every cold winter ride. The jacket has just what you're looking for, with a chest and shoulders that employ laminated, windproof Stratagon, a porous membrane that opens and closes with warmth and cold for excellent ventilation and protection. Matched with insulated back panels of Roubaix Quantum Leap fleece fabric, the jacket retains warmth and expels moisture. The advanced fit is closely tailored, while offering ample room for a jersey or base layer. Special collar snap works with the full-length zipper to seal in warmth or allows venting without flapping in the wind. Other details include reflective accents, three large rear pockets, and a zippered security pocket with media port.
