Gi vs no-gi in BJJ comes down to the uniform, and that one change affects almost everything. In the gi, lapels and sleeves work as handles, levers and choking tools. In no-gi, wearing a rash guard and shorts, everything slips. The pace goes up and control comes from the head, arms and hips. Both share the same positions, but you hold them in different ways.
What fabric changes on the mat
The gi adds friction and grips. You feel the gap from your very first roll.
With the gi, one good sleeve grip can freeze an arm for a minute. Open guards are built on sleeve and lapel grips, and your legs can wrap inside the folds of your opponent's pants. The game is slower and more tactical. At times it feels surgical.
Without the gi, sweat makes everything unstable. You cannot hang on to someone. You control their structure instead: underhooks, head control, wrist control. Exchanges are shorter and more explosive.
Submissions that change
Some techniques only exist with the gi. Collar chokes need fabric, like the cross collar choke from closed guard or the bow and arrow from the back. Judoka know the family as okuri-eri-jime (sliding collar choke).
Other attacks get better in no-gi. The guillotine is nasty there because the head escapes less easily from a bare arm. The rear naked choke stays the go-to finish from the back in both. The triangle choke goes on faster in no-gi, and it is harder to defend when the arm slides through.
IBJJF rules: what differs
The points are the same. Takedowns, sweeps and knee on belly score 2, a guard pass scores 3, and mount or back control score 4. The big difference is leg locks.
| Gi | No-gi | |
|---|---|---|
| Straight ankle lock | Legal for all adults | Legal for all adults |
| Knee bar, toe hold | Brown and black | Brown and black |
| Heel hook | Illegal for everyone | Legal for adult brown and black |
You will find the full official table by age and belt in our guide to IBJJF rules and points. Other grappling rulesets allow heel hooks much earlier, which completely changes how people play with the legs.
The no-gi uniform
For training, any rash guard and shorts with no pockets or zippers will do. Skip shorts with zipped pockets and hanging drawstrings. Fingers get caught in them.
IBJJF competition rules are more specific. The rash guard must be tight and cover the torso down to the waistband of the shorts. It must be black, white or black and white, with at least 10% of your belt color. A top entirely in your belt color is also accepted. Shorts reach at least mid-thigh, stop above the knee and have no pockets or hard parts.

Which one to start with
Our position is clear: start in the gi if your gym offers it. The fabric slows the exchanges, which gives your brain time to understand what is happening. You learn to control with grips first, then find out in no-gi that you have to control without them. The other way around is harder.
No-gi still has good arguments.
- You come from wrestling or MMA, so no-gi builds on reflexes you already have.
- You want carryover to MMA. No-gi is closer, and judo for MMA covers the stand-up side of that question.
- You hate the heat. A rash guard is much easier to bear in summer than a gold weave gi.
Doing both is best. One session of each per week works well if the schedule allows it. The gi makes your no-gi more precise. No-gi makes your gi game less dependent on grips.
Hygiene, the overlooked part
No-gi exposes more skin. The rash guard and shorts limit direct contact, but arms, legs and faces rub against partners and the mat all session. Wash your kit after every class and shower soon after training. Stay off the mat with a suspicious skin lesion, and see a doctor if in doubt before you train again.
A judoka facing the choice
A judoka feels at home in the gi: they grip, they fall, they know how to pull a sleeve. In no-gi they lose half their standing reference points, because their kumikata (gripping system) no longer works. That makes no-gi an excellent exercise for a judoka. It forces work on hips and positioning instead of hands. We cover this in more depth in BJJ vs judo, and the sport as a whole on our Brazilian jiu-jitsu page.
One last training tip. When you move from gi to no-gi, start from the same position for a month, half guard for example, and write down what stops working without fabric. That list shows you which techniques relied on grips and which relied on a real understanding of the position.
