Engineered for deep winter surface mining and freezing job sites, with our 100% Certified reflective print on the back: a hard hat skull and check mark inside the Miner Strong gear. At 12 ounces, our Grey 100% Certified Hoodie combines a dense fleece core to trap body heat with a rugged exterior that blocks wind and shrugs off wear-and-tear. The grey body pairs with denim or work pants, and the back print stands for the training and time it takes to earn your place on the crew.
