Dry Heat
It’s funny how much waiting happens at the crag: Belaying, spotting, gawking, sharing beta—these don’t require a ton of energy. What’s not funny is how far your core temperature can drop on cold days during inactivity. Solution? The Sierra Designs DriDown Gnar Lite jacket ($229; sierradesigns.com). While at first glance it looks like any other 800-fill down jacket (and indeed its weight and warmth are comparable to most in that category), it’s the invisible treatment to the down itself that makes the difference.
