The Pearl Izumi AmFIB Cycling Bib Tights are the thickest, warmest, most winterized tights Pearl makes: and they're amazing. When those long summer rides are only a distant memory, sometimes you just have to get out and pedal. Even if it's freezing cold and raining. This is the legwear of choice for cyclists dealing with cabin fever. Great protection and an amazing chamois go a long way: visualize palm trees and bright sun!
