How to choose.
Choosing a BJJ gi
Gi sizes run from A0 to A5 and are based on height first, then weight. If you sit between sizes, a long (L) or heavy (H) cut adds length or width without going a full size up. Our gi size calculator gives you a size in under a minute.
Pearl weave vs gold weave
Pearl weave is lighter and breathes well — ideal for daily training. Gold weave is denser and harder to grip, which is why many competitors prefer it. Our Gold-Weave Pro Gi uses a 550 GSM weave; the Pearl Weave Gi is 450 GSM.
Gear for striking arts
For Muay Thai and kickboxing, satin shorts with a wide leg give full kicking range, and shin guards with instep protection are essential for sparring. Karate and taekwondo practitioners should check their federation's rules on gi weight and colour before competing.
Questions
Are EIGHTY8 gis IBJJF legal?
Yes. Our BJJ gis are cut to IBJJF competition standards. Always check the latest IBJJF uniform rules before an event, as patches and colours are also regulated.
Will my gi shrink?
Our gis are preshrunk. Wash cold and hang dry to keep shrinkage to a minimum. A hot wash or tumble dryer can still shrink cotton by several centimetres.
What is the difference between A2 and A2L?
A2L is an A2 with longer sleeves and pants, made for athletes who are tall for their weight. A2H is wider for athletes who are heavier for their height.
