Air it out on the mountain bike trails or urban byways with this vented Pro Dirt mountain bike short from Salomon. Unzip the zippered pockets and air easily flows through the Salomon Air Vent System™ to keep your lower torso cool on hot summer single-track runs. The Pro Dirt short has a dual short design that you can even wear as separate shorts provided that you remember that the Eschler antimicrobial chamois is attached to the inner Acti-Lite Lycra® Tactel® mesh short. (The outer Acti-Lite Cotton Touch Nylon does not have the same flatlock seam design as the inner short so consider wearing something beneath the outer short if you're going far.)
