The ideal all purpose mid-layer, the Icebreaker Women's Sport320 Tornado Zip Shirt is perfect as a layer over lighter weight Bodyfit, Nature or Superfine styles. Providing everyday comfort in 100% pure New Zealand merino wool, this top is soft and highly breathable, resists odor, minimizes moisture, and features no seams in the shoulders for ultimate comfort and movement. The flat seams and regular fit design offer a stylish feminine fit, while a three-way collar (zipped up, rolled down, open) provides excellent venting and warmth versatility. A drop back tail helps avoid waist gapping to maintain body heat, while a hidden pocket keeps your essentials close at hand. Machine washable, the low bulk Tornado Zip Shirt is perfect for travel, activewear, snowsports and everyday use.
