Champion Men's Big & Tall Jersey Pocket T-Shirt - Comfortable Cotton Tee for Casual Wear, Gym & Everyday Use

I'm both big and tall, and it's hard to find decent shirts that fill both of those categories (you'd be surprised how many clothing lines seem to assume if you're big you're under 5'6" and thin if you're over 6'5"). It has a very generous length and the shoulder box is very comfortable, feels sturdy an comfortable to wear.
