Seems well made and is very well-ventilated, great for hot weather but can be layered under a warmer jacket if needed. The fit is snug, but stretchy so the armor stays where it should be.I am a small woman (5'3" 105lbs) and Small fit great. My husband (6'2" 170lbs) got the Large, which fit great, and the sleeves were actually long enough for him, even with reach to the handlebars.I've seen other mesh/armor shirts like this for almost 3x the price, so these are a good value.Note that these are not abrasion- resistant so I wouldn't wear this on the road. But they're perfect for slow dirt on dual-sports.My one gripe: the yellow armor shows through the white. I guess I should have expected that. My husband got gray - no show-through.
