Bottom Line: A lightweight BJJ Gi makes training a lot easier, especially in hot climates like Asia and South America. Lightweight Gis also help you make weight easier, for competitors on the edge of their chosen weight class. Gis with a weight of under 350 GSM are generally considered “lightweight”, though you may be able to find Gis as low as 250-275 GSM.
A Gi is what makes you look like a real martial artist. To some people, it makes you look like a badass. To others, you look like a member of a cult.
The BJJ Gi is a little different to other martial arts. It’s usually strong, sturdy… and to tell the truth a little heavy.
That’s one of the reasons you might want to think about picking up a lightweight Gi for training, competition, or perhaps just for summer.
In this article, I’m going to break down the advantages and disadvantages of a lightweight Gi for BJJ, and present some of the best ultralight Gis you can get today.

Why Do You Need a Lightweight Gi?
Jiu Jitsu Gis are often really thick and heavy. Put the BJJ Gi against Gis from other martial arts like Karate or Aikido, and you’ll see the difference.
There’s a reason for this, and it’s hard to train BJJ if you only have a super-thin Karate Gi. But BJJ Gis still have varying levels of weight and thickness, which can appeal to a lot of people.
If you train anywhere hot, the Gi becomes unbearable after a while. It weighs you down, and feels like a lead jacket after a few hard rolls. That slows you down, makes it hard to move, and drains your energy.
Having trained in Brazil and Asia, with no air conditioning, I know this feeling too well!
When you’re competing in the Gi, it starts to feel like a big hindrance too. You need to weigh in with full uniform, so the heavier your Gi, the more weight you need to cut. A lightweight Gi could be the difference between making weight in a lower class, or having to go up against fighters bigger and stronger than you.
The practical benefits go on… if you need to carry your gear around all day, you’ll feel a lot better with a lightweight Gi. Even better if you’re travelling – you probably don’t want half your baggage allowance going just towards your Gi.
If that’s not enough, lightweight Gis are generally cheaper too! Who doesn’t want to save a little money?
Disadvantages of an Ultralight Gi
There’s really no massive downside to wearing a lightweight or ultralight Gi. But for a few reasons, some people may prefer a regular Gi.
When you buy a lightweight Gi, you need to ensure the quality is up to standard. Most top Gi manufacturers make an ultralight option that is up to their regular standards, but you can certainly get some that are weak, and tear easily.
The fit tends to be a little looser, which makes it easier to grip and manipulate. Plus it’s a little easier to get feet and hands caught, which bothers some people.
Also, while a heavy Gi in a hot Brazilian gym is kinda uncomfortable, it does make your training more intense, and increases the benefits. If you can stand it, you’ll be stronger at the end of everything. Like Goku’s weighted training gear.
So, while there’s no major downside to a lightweight Gi, they’re not necessarily essential. It comes down to personal preference.
What To Look For
There are a few things you want to look for when deciding on your lightweight Gi.
Weave is the biggest difference-maker in the weight of your Gi. It refers to the way the fabric is woven together. Different styles result in heavier or lighter Gis, as well as affecting the strength of the Gi.
Generally speaking, pearl weave is the best style for a light, yet durable gi. Other styles include gold weave, single weave and double weave (double weave Gis are usually the heaviest). Single weave style is very lightweight as well, but doesn’t tend to last as long as pearl weave.
GSM is “grams per square meter” – this is the weight of your Gi, so obviously if you want a lightweight Gi, you want a low-GSM Gi.
Most Gis range from 375-890 GSM, though you can find heavier or lighter. A lightweight Gi is generally under 450 GSM.
If you intend to compete, it’s a must that you double-check that your Gi is legal for IBJJF competition. Otherwise you could end up doing a tough training camp that’s all for nothing.
Getting the right size is a must. Both so that it fits comfortably, and also that it complies with IBJJF rules.
Finally, you almost always want to get a Gi from a reputable manufacturer – especially when you buy a lightweight Gi. It’s easy to pick up a Gi that feels great, but then tears the first time someone gets a grip on you.
If you’ve been in the BJJ game a while, you’ll recognize some of the biggest names. These brands are a staple in the game for a reason, and generally you can feel pretty safe picking up any of their products.
