Our tees are 300 GSM heavyweight cotton. Sweatpants are 350 GSM 80/20 cotton-poly fleece blend. Hoodies and crewnecks use premium heavyweight fleece. We don't cut corners on fabric quality.

Cold wash, tumble dry low, no bleach. Turn garments inside out before washing to preserve prints and graphics. This keeps your gear looking fresh for the long run.
