Even the hottest summer temperatures can't keep you off the trail, so put on the Mountain Hardwear Women's Canyon Pro Short-Sleeve Shirt and head on out. You'll stay comfortable all day in the lightweight, stretchy, moisture-wicking fabric. Though lightweight, the shirt is surprisingly durable, just in case you get off trail and end up bushwhacking through abrasive branches. Knit side panels keep you free to romp and roam, while the UPF sun protection and sun collar keep your skin shielded from the strong summer sun.
