The Grit in its name comes from the grit in its threads. This heavyweight tee combines the muscle of 6 oz. brushed cotton with smart details like breathable mesh underarm gussets that dissipate heat when you start moving. The chest pocket? Reinforced, divided for a pencil, and tagged with a small strip of reflective material. Even the seams are overengineered, stitched tight and smoothed for an all-day comfortable fit.
