A chilly descent will suck the power out of your muscles, but POC's AVIP Light Wind Vest will help keep your core warm so your engine will be ready to kick into gear when you hit the flats. This lightweight, 57-gram vest uses a full polyamide construction to block wind, but employs mesh side panels that will help you stay cool if you're pedaling hard and don't have time to change layers. A DWR treatment sheds light precipitation, hem elastic improves fit and reduces drag, and the reflective rear logo helps keep you visible when you're riding home at twilight.
