Field Test: This jacket wears like a long-sleeved shirt, which is why I reach for it time and again. Its thin polyester blend lies softly against my skin, with sweat-wicking side mesh panels that keep me from overheating on trail runs. I tie the layer around my waist at the base of a long mountain climb, and pull it on to traverse windy ridges and descents.
Why it’s Timeless: Runners always need a wind-cutting, light rain-shedding layer. $130; thenorthface.com —Lisa Jhung
