The ScorpionExo Men's Covert flannel shirt is a great piece of protective riding apparel. The shirt was designed to protect from abrasions and (God forbid) impact while riding.
The entire shirt has been lined with DuPont Kevlar, not just in the elbows like most Kevlar flannel shirts. All of the seams use the exo-stitch which is designed to keep the shirt together in the event of hitting the ground.
