So I've done some searching but haven't been able to settle on it. I need an armor jacket. I've been pushing my luck riding/racing downhill all summer without one. I don't need impenetrable protection everywhere. I do need something breathable as I seem to heat up easily. The dainese would probably be great but is way too much cash. (Thus why I haven't gotten one yet.) The question is if the SP-1 will fit. I'm about 6' tall 175lbs with a leanish upper body. Has anyone like me gotten the large to fit well or will it be hanging off of me? So far I've read that it seem to fit well on people bigger than me and that the medium is too small on someone leaner than me. Thoughts?
