Stay warm in the grey Thunder long sleeve t-shirt from Vitriol, made from a warm thermal waffle knit construction. White cyber sigilism branding embroidered on the chest compliments matching spiked graphics printed on the sleeves, and contrasts against macabre black art of a demon perched on a gothic gate on the front. Ribbed sleeve cuffs help ensure a snug, comfortable fit that traps warm air in and cold art out.
