02DERIVE Single Riders Jacket in Black GORE-TEX Material. - Color: Black - Material: GORE-TEX & Cowhide - Design: Single Riders - Zippers: With side and back pockets - Style: Stand collar, short length, slim fit for riding - Size: Feels like a size between S and M (34-36). For me, with a chest circumference of 95cm, I can wear it with a t-shirt underneath, but it feels tight. Considering wearing thicker innerwear in winter, I cannot guarantee it will fit, but I think a chest circumference of around 85cm +/- a few centimeters would be ideal. It seems to be designed slim for motorcycle riders and for stable operation during touring. GORE-TEX and waterproof zippers are used to handle sudden rain, and it also appears to be lightweight. The design is elegant and understated, suitable for women or everyday wear without any issues. The item has not been used, but please consider it as a pre-owned item when making your decision.
