What Our Gearhead(R) Experts Are Saying:"The Italian mesh back moves heat out fast, so I'm not cooking on climbs, and the two-way zipper lets me vent from the bottom without messing with the fit at speed."The Pearl iZUMi Pi PRO/BLACK Wind Vest is light enough to live in a jersey pocket all day and protective enough to change the ride when you pull it out. The stretch-woven front panel blocks wind without the crinkly, stiff feel that makes most vests annoying on fast terrain. Pearl iZUMi cut the torso short and trimmed the silicone hem so the fit stays locked down and out of the way, which matters when the pace is high and adjusting kit is not an option. GoFresh anti-odor treatment and PFAS-free water repellency round out a vest that holds up to repeated use without needing constant care.
