All NOGI shorts are made with a 100% stretch poly material throughout the whole short not just on certain panels. They have a smooth inside so there is no rubbing or catching on the skin while training, fighting, swimming, surfing, or just chillin' at home. These shorts also have a smooth Velcro closing system with a draw string inside for adjustability. All NOGI logos are embroidered, sleek, low pro, and not written all over the shorts so that you can look good wearing them outside of the gym. If you are going to be competing in these shorts, you can make a special request when ordering for larger print to be screened on the shorts before being shipped. There is also a high pocket on the right hip for your mouth piece, MP3, Ipod, or keys. The pocket is placed on the hip to avoid any swinging while running. NOGI backs these shorts with a 100% money back guarantee for ANY defects or even lack of comfort.
