Karbonite micromesh on the back and in stretch zones keep the jacket breathing while Karbonite ripstop reinforces the shoulders and elbows. A variety of vents make sure you stay cool while you're working hard on the trails. Zip off the sleeves and store them in the rear pouch when the conditions call for it. D3O armor is not included so you can roll your own compression shirt armor or add D3O into the back, shoulder and elbow pockets.
