Giordana's EXO System Bike Shorts turn fabric sourcing into an art form using four proprietary fabrics that enhance muscle performance and give you every advantage to slip through the air. First, it places Moovix at leg panels. This compression fabric works to support your muscles without squeezing them into submission using a hollow microfiber with a breathable honeycomb structure. Several of the leg panels are sewn with the new Grandfondo material, a lighter weight knit with an even higher threadcount than Moovix. Finishing off the legs is Zaffiro, which, while featuring a soft inner layer, resists abrasion to extend the life of your shorts. Drawing from the FormaRed series, the EXO System Bib Shorts also use the Ametista Core Contour. In addition to a heavy gauge Lycra, carbon threads reinforce and support the knit. Carbon allows omni-directional stretch for a comfortable fit around your waist. Illusion mesh panels allow for ventilation as do the AeroFix bibs. Flatlock seams and shaping that conforms to the body while in cycling position turn the EXO bibs into a second skin, helping to slice your way through the air. Finally, the chamois uses the Cirro O. F., a waffle-textured memory foam that is infused with antimicrobial aloe vera particles. Its 4mm padding and channel design keep you comfortable and dry.
