The Pearl Izumi Men's Interval Cycling Shorts uses muscle hugging Lycra for a performance feel from the moment you slip them on. They have a sophisticated seven panel design that uses the stretch and support of the fabric to simplify the number of seams, allowing the short to follow your every movement. Laser cut bib straps and hems create a seamless transition to skin and perfectly balanced support. In-R-COOL technology provides additional cooling performance as you turn up the heat and lay down the power.
