Giordana's Silverline Bib Shorts offer remarkable riding performance with a certified Power Lycra fabric called Zaffiro. It's woven to stretch in all directions, moving with you to hug and support your muscles so you ride stronger longer. You also get Giordana’s Nimbo OmniForm insert that contours to you for top comfort and protection, and returns to its original shape after every ride. And, these fine bibs boast moisture-transferring Giordana Moxie microfiber panels on the front and rear thighs so you stay dry and comfortable. Giordana also incorporates their modified Core Contour System that wraps the waist with ergonomically designed mesh inserts to eliminate bunching while riding and that vent to keep your core cool. Meanwhile, the uppers are made of breathable, wicking micromesh, there are four-needle flat-stitched seams and soft doubled Lycra at the cuffs to keep these fine bibs in place. You also get reflective accents for visibility.
