"Medium fits like a small, good for aerodynamic but not comfort."
"I haven’t used it in rain yet, but the fabric feels like high quality. It feels like it might be my best waterproof jacket. I can’t wait for a rainy ride to test it out. As for fit, I’m 6 ft and 165 lbs; so on the slim side. I got a large. The chest is fine. It’s snug, which is good. Standing at ease, the arms are just right. But when stretched forward, they are a tad bit short, but should be fine. The torso is the shortest dimension. The waist should come down a little more to cover my butt. If an XL was available, I’d probably exchange it, but overall I think the L should work."
