Offering a longer cut for added protection, the new Pearl Izumi Infinity Long Short provides a stylish alternative to the shorter Pearl Izumi Infinity Short. Stylish, yes, but the longer length has some practical advantages too. The additional coverage provides a bit more warmth in chilly conditions and sun protection too. But just like its shorter cousin, the Pearl Izumi Infinity Long men's running short offers laser perforated side panels for excellent ventilation plus the always effective UltraSensor fabric. This material utilizes one-way capillary action to transport moisture to the outer surface for quick evaporation.
