The Atama Ultra Light is the ultimate tool for the serious competition athlete. It was designed after exhaustive testing to find the perfect balance between lightness and strength. Tested and approved by the entire Atama Team. The pants and collar are made of military Rip-Stop fabric. No seam on the back of the jacket and reinforcements on all stress points., The Ultra Light Series was developed for maximum comfort, lightness and allowing the fabric to dry quicker, but make no mistake, it is super strong like most regular gi's. This gi is great for training on hot days and competitions, on most BJJ organizations you must weigh-in with the gi on, which makes the New Light a great choice for those who need to make weight on tournaments.The Rip-stop pants are reinforced on the knee area to provide extra protection and durability.
