The Brevet Element Wind Jacket pairs a nylon body built to block the wind with stretch side panels in a nylon-elastane blend, so the jacket moves with us instead of fighting the ride. The fit sits looser than Rapha's Pro Team ranges, built to layer over a jersey rather than hug the body. What Our Gearhead® Experts Are Saying:"I've stuffed this into a jersey pocket at the start of a ride and forgotten about it until the temperature dropped on a descent. The rear zip pocket doubles as its own stuff sack, so there's no separate bag to dig for when the weather turns."
