The Mobile Cooling® 1/4 zip long sleeve shirt by Fieldsheer provides excellent sun protection and cooling in a stylish design. Ideal for working in hot conditions or outdoor activities, this shirt is made with DriComfort GEO 365, a chemical-free, mineral-infused fabric that wicks heat and moisture from the body and dries four times faster than traditional fabrics. It uses no harsh chemicals or treatments that could wash out over time. With UPF50 sun protection, vented sides and back for added comfort, and Odorsheer® technology to control odor-causing microbes, this shirt is perfect for all-day wear. The 1/4 zip design with a mock collar makes it versatile for both day and night use.
