Ask a skier like Nolan Kasper and he'll be quick to tell you that layers need to guard you from the wind and keep you warm on frigid lift rides. But they also should be breathable enough to vent the sweat you build on the ride down, and mobile enough to let you ride unhindered. The good news is that garments are always improving, with new fabrics and fits that vent, stretch, and shelter better than ever before. Here's what to look for.
For high-aerobic activities, you want a light pair that wicks enough to prevent evaporative cooling. For mid-aerobic activities, look for mid-weight fabrics with more insulation. [Icebreaker 200 Legging, $80, icebreaker.com (left); Patagonia Capilene 4 Expedition Weight, $79, patagonia.com (right)]
