Fight the cold with three layers of heat-trapping power to keep you warm when taking on hazardous jobs in the cold. HiVis panels, reflective piping and a RefrigiWear logo on the left sleeve help you stand out when it matters most. Plus, Grip Assist on sleeves helps prevent anything from falling from your grasp and tough, durable abrasion-resistant panels can take a beating without fraying. Finally, a sweatshirt that works as hard as you do. Sizing Instructions: For the most accurate fit, take your measurements over the base layer of clothing you intend to wear with this RefrigiWear gear (such as thermal underwear, jeans or a sweatshirt) and refer to the size chart for this product.
