Base layers in a technical wool blend bring together natural wool and performance fibers to create a layer that works with your body when the pace picks up. The Kari Traa Faith Half Zip is perfect for helping you stay comfortable through changing temperatures and shifting intensity. Featuring our Female First body mapping technology, this semi-seamless top integrates supportive structure and ventilation where you need it most: underarms, breast area, and back. With the eye-popping oversized Rose pattern, the Faith is for active women who want to look as good as they perform.
