A chilly descent will turn you into an ice cube in minutes, but POC's AVIP Light Wind Jacket will help keep your core warm so you'll be ready to put the hammer down when you hit the next climb. This ultralight 78-gram jacket features a full polyamide construction to block wind, but employs mesh side panels to help you stay cool if you're pedaling hard and don't have time to change your layers. A DWR treatment sheds light precipitation, a hem elastic improves fit and reduces drag, and the reflective rear logo and fluorescent cuffs help keep you visible when you're riding home at twilight.
