Design Philosophy Good thermoregulation is key to efficient riding in hot climates. Endura's Xtract Lite Short helps keep your core temperature cool by moving sweat away from your skin. 500 Series Pad The 500 series pad excels in hot climates by using DisperseFoam™, a global exclusive for Endura. This disruptive foam cell construction provides superior drying and dramatically improved air permeability compared to conventional PU foams. 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.
