The MAAP Flow Jacket is a lightweight, wind-resistant cycling jacket that cuts wind across the leading edges and rear, the zones that matter most on a fast descent. Air-permeable ripstop side panels and a laser-cut perforated rear panel release heat, so the jacket stays comfortable on the climb back up. What Our Gearhead(R) Experts Are Saying:"The zip is why I wear the Flow Jacket anywhere from 46 to 68 degrees Fahrenheit, because I can open it from the bottom or the top as the effort changes. When the weather clears, the zippered rear pocket takes the jacket into itself and it rides along as a small bundle."
