No gi jiu jitsu is Brazilian jiu jitsu trained without the kimono, in a rashguard and shorts, where every grip has to come from your opponent's body instead of their clothing. Gi jiu jitsu gives you collar, sleeve, and pant grips. No-gi takes them away and leaves you underhooks, wrists, necks, and hips. Same submissions, same positions, different handles.
The usual advice is to pick based on your goals. That sounds reasonable and it is close to useless, because it ignores the one factor that decides whether you actually train enough to improve.
What changes when the kimono comes off
Three things, in order of how much they affect you as a beginner.
Grips. This is the whole difference. A gi is a set of handles bolted to your opponent, and half of gi jiu jitsu is deciding which handle to hold. Strip it and you are down to what the body offers: wrists, elbows, the neck, an underhook, a leg. Fewer options, and each one is harder to keep.
Pace. No-gi is faster, and sweat is the smaller reason. The bigger one is that you cannot stall. In the gi you can take a deep collar grip and hold a position while you think. Without fabric there is nothing to anchor to, so positions have to be re-taken continuously and the round turns into a series of scrambles.
Pressure over friction. Gi passing leans on grips and drag. No-gi passing leans on hips, shoulders, and head position, because that is what still works when your hands slide off. Most people who cross over say no-gi taught them how much of their gi game was fabric doing the work.
The grip map: gi handles to body handles
If you already train one, this is the translation you need for the other.
| Gi grip | No-gi equivalent | What you lose in the swap |
|---|---|---|
| Collar grip | Collar tie or head control | Holding power. A collar tie slips, a lapel does not. |
| Sleeve grip | Two-on-one or wrist control | Duration. Wrists take constant work to keep. |
| Pant grip for passing | Ankle or knee control with the shoulder driving | Static control. You now pass with pressure and timing. |
| Lapel and collar chokes | Rear naked choke, guillotine, arm triangle | Volume. There are far fewer choke entries without cloth. |
| Spider and lasso guard | Butterfly, single leg X, and leg entanglements | Nothing, arguably. Leg locks are richer in no-gi. |
Notice the last row. The common line is that the gi has more technique available, but leg entanglements are more developed in no-gi precisely because grips are scarce. It is not less technical, it is technical in a different currency.
Your gym's class schedule decides this, not your goals
Here is the part the goal-based advice misses. Almost every gym is gi-heavy. A typical week is four or five gi classes and one or two no-gi sessions, often a single Friday open mat. If you decide you are a no-gi player at a gym like that, you have just signed up to train once a week.
Once a week is not a training habit, it is a hobby you will quit inside four months. Three sessions a week in the format your gym actually runs will beat one session a week in your preferred format every single time, and it is not close. Frequency dominates format at every level below competition, and it dominates hardest in the first year when you are building base movement.
So the decision is mechanical. Look at the timetable, count the classes, and start in whichever format your gym runs at least three times a week. If both clear three, take both from day one, because the crossover is the fastest way to find out which parts of your game are technique and which parts are fabric.
If neither clears three, the honest answer is that you have a schedule problem rather than a style question, and it is worth checking whether another gym in range runs a fuller week.
The self-defense argument, and why it points the other way
The most repeated case for starting no-gi is that nobody attacks you in a kimono. You will find that line in most of the top articles on this topic, usually stated as settled. It sounds obvious and it does not survive contact with what people actually wear.
A denim jacket has a collar. A hoodie has a collar and sleeves. A work shirt, a coat, a zip-up: all of it grips, drags, and chokes in ways that are much closer to a gi than to bare skin. If your reasoning is that training should resemble a real altercation, then for most of the year in most climates, the gi is the more realistic simulation, not the less.
The genuinely good arguments for no-gi are different ones, and they are strong enough that they did not need the bad one. MMA and professional grappling are no-gi, so if that is the goal, train the ruleset you will compete under. Wrestling and clinch entries feature more heavily, and standing exchanges are where physical confrontations begin. And no-gi is a cheaper start, because a rashguard and shorts cost a fraction of a decent kimono.
What we would not do is choose no-gi believing the gi is unrealistic. Choose it because you want the ruleset, the pace, or the wrestling.
What you actually wear for each
Gi training needs a kimono, a belt, and a rashguard or shirt underneath for hygiene and skin protection. No-gi needs a rashguard and grappling shorts, and often spats if you dislike mat burn on your legs.
The rashguard is not optional in no-gi and it is not a fashion choice. Bare skin on the mat means friction burns, staph exposure, and a partner sliding off you at the exact moment you needed the grip. A fitted synthetic top solves all three. Ours is the Umbra Rashguard, built for no-gi rounds and gi sessions alike.
One thing to plan for either way: no-gi puts more sustained friction on your head and ears, because head position replaces the grips you no longer have. That is how cauliflower ear starts, and it is worth reading the six hour treatment window before it happens rather than after.
How the rulesets actually differ
Most comparisons skip this, which is strange, because the rules shape the training more than the clothing does.
Gi competition under IBJJF rules bans heel hooks and knee reaping at most belt levels, which pushes the game toward passing, sweeps, and upper body submissions. Modern no-gi rulesets, particularly submission-only and ADCC formats, allow heel hooks, and that single difference reorganizes everything below the waist. It is why leg locks are a specialty in no-gi and a controlled sub-game in gi.
Scoring differs too. Gi competition is generally points-based with advantages, which rewards holding and advancing position. Submission-only no-gi events remove points entirely, which rewards hunting finishes and punishes stalling. Train under one long enough and it shapes what you instinctively do when a round gets tight.
Belt progression across both
Ranks come from the same system. There is one belt, and it does not care which format you earned it in, though many gyms weight gi performance more heavily for promotion because the gi is where they run most of their curriculum. Some no-gi specialists sit at a belt longer for that reason alone.
If you want the full progression and the realistic timeline at each rank, we covered it in the BJJ belt system guide.
Frequently asked questions
Should beginners start with gi or no gi jiu jitsu?
Start with whichever your gym runs at least three times a week. Frequency matters far more than format in the first year, and most gyms are gi-heavy, so for most beginners that answer is the gi by default. If both formats are well covered on the timetable, train both.
Is no gi jiu jitsu harder than gi?
It is harder to control and easier to start. Positions slip more without fabric, so holding anything takes more work, but there are fewer grip variables to learn at the beginning. Gi tends to feel slower and more technical early, then reveals its complexity as you add grips.
What is the difference between gi and no gi bjj?
The gi provides collar, sleeve, and pant grips, a slower pace, and upper body submissions built on cloth. No-gi removes those grips, speeds the pace up, leans on underhooks, wrists, and head position, and develops leg entanglements much further. The positions and principles underneath are the same.
Do you need a rash guard for no gi?
Yes, practically speaking. Most gyms require a fitted top for hygiene, and bare skin on the mat means friction burns and more exposure to skin infections. Grappling shorts and a rashguard are the standard kit, with spats optional for leg coverage.
Does no gi count toward your belt?
It does, since there is one ranking system for both. Promotion practice varies by gym, and because most gyms run their core curriculum in the gi, no-gi-only students sometimes progress more slowly on paper even when their grappling is strong.
