At the beginning and end of mountain bike season, the weather tends to become a bit more unpredictable. With a flash of precipitation here or there and quickly dropping temperatures as the sun sets, you'll be glad to have the Pearl Izumi Men's Summit AmFIB Convertible Pants keeping you comfortable. These pants feature the ELITE AmFIB Softshell material that resists wind and water to minimize chills, and have a Thermal Fleece lining to regulate temperature while providing a soft texture against your skin. PI Dry technology is focused at the knees to mitigate sweat, minimizing chills. The pants convert quickly and easily into softshell shorts when the sun comes out, and the hem features zippers so you can get the pants off without removing your shoes. External adjustment points let you customize the waist fit, and the cut is mountain-bike-specific so it stays out of your way as you ride. BioViz elements reflect to maximize your visibility in low light, so if the few minutes you spend on the road back to your car come after sunset, you'll be just a little bit safer.
