This t-shirt is made of a 50/50 cotton/poly blend fabric which helps to wick moisture away from the body. It is a great all around shirt for everyday active living! The wicking properties of the fabric keep moisture off your body on hot days but it still has the soft smooth feel and classic look of a cotton tee. This shirt comes in Adult sizes, which is the same as men's sizing so women typically need a small or medium. It has the In We Go Canyoneering logo on the front left side and the rappeller icon on the front bottom right side and on the back at the collar.
