MWG’s EVOLUTION FR/AR long-sleeve t-shirt is built to work as hard as you do. It is constructed with an inherent flame-resistant (FR) fabric that is quick-drying and incredibly breathable. Flame-resistant segmented reflective tape is heat sealed in order to reduce the bulk that is often associated with high-visibility striping, making this shirt as comfortable as it is safe. It has an ATPV of 11 (!!!) while remaining lightweight and breathable. MWG EVOLUTION is a must-have if you’re working with high voltage and you’re outdoors in the summer. It’s also great for layering in cold weather.
