You can't do sprints in a walk-in freezer. You can't lift weights on ice. You can't do burpees in the frozen food section. The truth is, it's going to be hot out there, but this adidas HEAT.RDY Training Tee is built to handle it. Soft, breathable material absorbs moisture to keep you dry and feeling motivated, not defeated. Ventilation in key sweat zones keeps the air flowing so you stay cool.
