Breeze Blocker - Stio Kirby Windshirt: By using thicker nylon yarns and an unusually dense weave, the Kirby offers more wind protection than gauzier sun shirts, making it ideal for high-alpine hiking and shoulder-season trips. “It kept me warm during a climb of 14,265-foot Quandary Peak, and I didn’t need to pull on a sweat-trapping shell on the gusty summit,” reports our Colorado tester. And on splashy spring paddling trips, the nylon dried within 10 minutes in breezy, 65°F conditions. Caveat: In temps higher than 70°F, it’s overkill. $115; 9 oz. (m’s L);
