Our 1/4 Zip Shirt is constructed with Power Grid™ 4-way stretch fabric that offers enhanced comfort and range of motion. The unique grid construction maximizes warmth, minimizes weight, and improves breathability. We decreased the fabric weight by over 20% while increasing the PPE Category from CAT 1 to CAT 2.
