The GEO7™ Rapid Half Zip isn't just a shirt, it's an attitude. Inspired by some of the our most popular designs, it features a mix of performance fabrics for enhanced layering and tactical utility. The body uses a 92% polyester/ 8% spandex fabric that wicks away moisture, while the sleeves, shoulders, and collar consist of polyester/spandex fabric with two-way stretch, quick-dry properties, and additional moisture wicking.
