The addition of a couple of hot weather beating extras is what really sets these shorts apart however, including a UPF50+ treatment for the fabric and a 500 series temperature regulating pad. The 500 series pad excels in hot climates by using DisperseFoam, a global exclusive for Endura. This, combined with silver yarn fabric with cool touch in a Continuously Variable Profile high stretch pad makes the 500 series pad the go to choice for hot weather riding.
