GU white shirt! New, unused! I bought this to wear when exercising, but I bought the wrong size and haven't worn it once. The design is breathable, although it's hard to see in the photos, with ventilation on both sides and the back. See photos. It doesn't look too big for an XL ^ ^ It's a see-through, breathable material.
