OK, I ride a 250 and ride it hard. I've gotten to the point where I just can't ride without protection and feel comfortable. And it gets hot here in Nevada. Solution.... Tourmaster mesh jacket! Wow, this thing is cool! Has large mesh holes thru-out and a zip-out liner for cooler weather. Hard protection in shoulders + elbows, and has a softpad covering the back. Anything over 15mph gives you a cool breeze. My only complaint is the backpad is not perforated so after an hour of hot riding that area does pick up some sweat. $175.00 out the door, best thing I've got in a long time!
