This comfortable Guy Harvey Woodblock Pro UVX Performance Long Sleeve Shirt features a moisture management technology that wicks moisture away while providing odor control. The fabric provides a UPF Sun Protection Rating of 30+ and is breathable by moving perspiration from the skin to the outside of the fabric for rapid evaporation. As moisture is produced by the body, it moves through the hydrophobic layer of fabric, which acts as a pump to move the moisture to the outer surface. This synthetic fabric is light, breathable and durable. Available in Light Blue; Sizes S-2XL.
