Third in Capo's extensive jersey lineup, the GS jersey brings some of Capo's best hot weather technology within reach of self sponsored cyclists everywhere. The GS short for Gruppo Sportivo uses highly technical fabrics that combine advanced anatomic design, muscle support, and thermal regulation properties with the streamlined race fit that you've come to expect from Capo.Capo constructed the majority of this jersey with its new Carbon ES fabric, which is a highly elastic, dual knit microfiber polyester with visible antimicrobial carbon core threads running throughout. Carbon threaded fabrics are known to enhance circulation, with the added benefit of keeping odor in check something that you and your riding partners will greatly appreciate. The Carbon ES material also accelerates moisture transfer and drying time, while keeping you effectively shielded from harmful UV rays.The elastic WarpStretch microfiber panels yield a super contoured fit and contain an active hydrophilic treatment that pulls moisture up and away from your skin. The GS jersey's underarms use contrasting Eyelet Mesh microfiber panels that have a distinct waffle like texture. This creates a fine gauge surface that's raised off of your skin. This means that you have built in air vents that keep you cool and expedite drying time.The jersey's full length zipper with self locking slider makes one handed adjustments a simplified affair. While you're climbing, leave the slider in the upright position, and you'll be able to open the zipper with a free hand. At the top, flip the slider down to keep it locked in place. No more wasted energy fumbling for proper ventilation.Three back pockets hold your tools and extra gear, Luminescent cuffs make you more visible in evening traffic, and the silicone waist keeps the fit of the jersey secure.
