The SHAPE. GLASS. SURF. logo is a reference to shaping, glassing and then surfing a board you've made with your own hands from start to finish - A feeling only few know and experience.  Includes the classic logo on the right arm sleeve.  
 
This is my favorite t-shirt fabric and cut.  I've been wearing them for the past year and honestly love them!  Soft and breathable while durable and comfortable.  60% Combed Ring-Spun Cotton, 40% Polyester.  Pre-washed fabric (for shrinkage).
