It is double sided and reversible. Wear the tshirt one way, and see the outside of the map. Flip it inside out and you will see the inside of the map. A brilliant 2 in 1 design. The tshirt is unisex and in my opinion would fit upto a size 10 female, or a 36" chest male (google says this is about a 12-14 year old boy).
