Icebreaker Drive Shirt (Winter 2013)

$140 | icebreaker.com

This long-sleeve, half-zip shirt is made of mid-weight merino wool, with a touch of elastane for an athletic fit. The fabric is water resistant, and, unlike synthetic tech shirts, doesn’t hold odors. It’s the perfect base layer for winter runs, with thumb loops to keep your palms cozy and a handy zip pocket at the chest. (The women’s version is called the Dart.)
