This is our size guide for our T shirts, Sweatshirts and Rash guards. Any questions feel free to drop an email to me at

Size guides are in cm and inches: Our sweatshirts are made slightly baggy or loose fitting. Rash guards are made to a close fit, if you want baggy/loose then consider going a size up. Our t shirts have an athletic cut, broad shoulders short sleeved, if you want a looser fitting t shirt consider going up a size also. 

Where possible sizes range from small, medium, large, extra and 2xl in size. Some of our rash guards include a 3XL. For anything outside of these sizes send an email and I promise to try and accommodate.
