REI Winterflyte Windshirt
Here's what other sites are saying:
When it's too cold for a base layer alone and too warm to add a heavy jacket, the men's REI Winterflyte Windshirt offers just the right amount of warmth for cross-country skiing or running. This mid layer is body-mapped to optimize performance, combining a windproof/waterproof front panel with breathable, wicking, fast-drying fabric on the back and sleeves. The windshirt's front panel also offers 4-way stretch for ease of movement. Thumbhole cuffs ensure arms stay fully covered when your skiing pace picks up. Long front zipper allows ventilation adjustment when you heat up; the locking zipper won't bounce around as you move. Flat seams minimize chafing; ergonomic seam placement also lets you move comfortably. Zippered chest pocket with headphone port can secure your music player. The men's REI Winterflyte Windshirt also has reflective trim that increases visibility in low light.
