Material

In general, Jiu Jitsu Gis are made from 100% cotton however, there are exceptions to this, such as the Hayabusa GSP Rising Sun Jiu Jitsu Gi which has Bamboo woven in to its fabric.

The type of "weave" used to construct a Gi is something that you should be aware of when buying for the first time, as this will reflect on the physical weight and durability of the Gi.

There are many different kinds of "weave" out there, so we have listed them different options below to help you get a better understanding.

Single weave

The majority of Gis out there are Single Weave and some brands offer the option of a Light Weight and Heavy Weight version. 

If you are looking to buy your first Gi, then Single Weaves make a great choice as they are normally the least expensive. Their relatively low cost is due to the lesser amount of material used to make the Gi using the basic Single Weave construction. GRIPS & VENUM!

Pearl weave

Some BJJ purists say that weave variations outside of the Single, Double and Gold Weaves are used to help their products differentiate themselves from the rest. However we do know, that Pearl Weave Gis, like the Spider Jiu Jitsu Gi and Hayabusa Shinju Pearl Weave Jiu Jitsu Gi are Pearl Weave and that they are light in weight akin to that of the Single Weave. GRIPS

Honeycomb weave

As with the Pearl Weave, this further variation on the Single Weave offers another light weight option. The name comes from the Honeycomb like pattern of the weave that can be seen when view up close.

Double weave

This kind of weave produces very heavy, durable and long lasting Gis. Often used for Judo, this weight of Gi has declined in popularity for Jiu Jitsu practitioners in recent times, with preference for Light Weight Gis being the more popular choice. The relatively expensive cost of Double Weave Gis is due to the increased amount of material used for their construction too.

Gold Weave

Long lasting and durable like Double Weave Gis, Gold Weave are normally heavier and again more expensive than their Single Weave counterparts. 

The aim of this kind of Gi is to combine the best of being both light weight yet strong and durable. In essence, replicating and combining the most desirable properties of both the Single and Double Weave Gis.

The Hayabusa Goorudo Gold Weave Jiu Jitsu Gi is an excellent example of this kind of long lasting, hard wearing Gi.

Ripstop

Similar in appearance to canvas like material, Ripstop is designed to reduce tearing as much as possible. 

The main pro of Ripstop is it's light weight, however as tends to be the case with light weight materials, you may find that your opponent will have a better chance of applying a tighter grip on your Gi during training or competition.

Triple Weave

A relative newcomer, this type of construction was first used on the Hayabusa Mizuchi Pro Jiu Jitsu Gi and Hayabusa Kanji Pro Jui Jitsu Gi.

Unlike the name might suggest, this is not a material that is three times as thick as a Single Weave, but is in fact a variation of the much lighter weight Ripstop material. The properties of the Triple Weave are therefore light weight and durable.

Weight

BJJ Gis are available in different weights, which can sometimes add further confusion for a beginner when deciding what to buy. The weight of a Gi will ultimately be based on your own personal preference over time. 

Gis are measured in gsm (grams per square meter), a system used to quantify the density of a fabric. We have listed the commonly used fabric weights that you will find below:

420 gsm

This weight of material is used for a lot of Light Weight Gis and is popular for those competing in tournaments. Whilst strong enough for regular use, a lot people prefer to wear a heavier weight for everyday training.

450 gsm

Again, popular for competition use, this weight is naturally more durable than a 420gsm Gi and offers a good balance between weight and durability.

500 & 550 gsm

As expected, 500gsm and 550gsm Gis are in the Heavy Weight Gi category and usually this comes with an increased price tag too. Gis of this weight are long lasting and very durable.

Appearance

Ranging from the minimal to the outlandish, Jiu Jitsu Gis are available in a variety of designs to cater for all tastes. The favoured design will usually include a vertical brand logo patch on the arms or chest of the Gi, as seen on Hayabusa's Jiu Jitsu Gi designs.

Like with any range of sportswear, style is down to your own personal preference, however in BJJ there can be restrictions on the appearance of Gis when competing (see IJJBF guidelines at the end of this guide). Again, as with other sports, the more flashy the design of your clothing or equipment, the more attention you will draw to yourself! Unless you're just a naturally super confident person, we'd recommend that you get your technique up to scratch before being the centre of attention down at your local club.

Colour

The same as design styles, Gis also come in a variety of colours. Traditionally the most popular colours are; White, Black and Blue. If you are a beginner at a new club it is always worth finding out if there are any restrictions about the colour of Gi allowed before making your first investment. It has been known for new practitioners to make a purchase of a new Gi without consulting their instructor first, only to find out that the colour they have chosen is not allowed at their club!

By no means a hard and fast rule, the colour of Gi is sometimes linked to the experience and rank of it's wearer. Beginners and traditionalists normally tend to opt for a White Gi and we believe you can't really go wrong with this colour. Mainly because White Gis tend to be a universally accepted colour with regards to club and gym restrictions. 

Blue Gis are again popular, and as with wearing White, as a beginner you won't draw any unwanted attention to yourself early on in your BJJ career. 

Black Gis, although becoming popular with practitioners at all levels, has normally been the colour of choice for more experienced and higher ranks.

Size

Due to the variations that exist between brands, it is always recommended that you check the size guide for each brand before buying. Adult Gi sizes are standardised in to the categories shown below. To simplify each size without using measurements, we have labelled each one with corresponding; Small, Medium, Large and X-Large to give you an idea.

A1: Small
A2: Medium
A3: Large 
A4: X Large

Sizes A0 (X-Small) and A5 (XX Large) are also available but those listed above are the most common.

It is important to note that not all brands offer a gi that is sized and cut specifically for women. However brands like Grips Athletics™ do have Gis that are designed and cut for women. Their Amazona Womens BJJ Gi is a an example of this kind of specially designed Gi. 

For Women's sizes, the equivalent Small to X Large sizing guide is the same, however you will notice that before the number will be either the 'F' or 'W'. 

As with the standard Adult sizes, it is advisable to consult the relevant brand size guide before making your choice.

F1: Small
F2: Medium
F3: Large 
F4: X Large

Pants

Thankfully for the first time Gi buyer or beginner the variations in Gi Pants is fewer than that of Gi Jackets. 

However, pants are available in varying weights, but are generally classed in to the two material categories below:

Cotton twill

Some people find Cotton Twill the more comfortable, however this is down to personal preference and opinions will vary. 

Ripstop

The main benefits of Ripstop over Twill is that it is much faster to dry and is light weight. There is an unresolved argument between practitioners that the thinner Ripstop material makes it easier for your opponent to maintain a stronger grip than on thicker, heavier Twill material pants.

The quality of stitching on the pants (and the Gi in general) will also be a major factor in the durability of the Gi. It doesn't matter if you opt for either of the two choices above, if the stitching that holds everything together isn't of a high quality then you could be dealing with much more problematic issues than comfort, weight and fit!

Shrinkage

Whilst the majority of Gis today are described as pre-shrunk, don't count on this and it is wise to be cautious and expect some shrinking from all brands of Gi. The average shrinkage after washing and drying is usually in the region of 3% (consult individual brand washing guidelines for specific details). 

Washing and drying instructions will vary from brand to brand, but we would normally advise that Gis are washed in cold water and are allowed to dry naturally to prevent any unwanted shrinkage.

By its very nature, cotton absorbs water and expands as a result. During the drying process, cotton shrinks back down to it's tightest and most condensed form, this is where the shrinkage occurs. 

How Much To Pay?

The price ranges of Jiu Jitsu Gis varies vastly and was with anything that you buy, you normally do get what you pay for in terms of quality.

However it is important to note that the higher the price tag doesn't always mean superior quality and there are excellent quality Gis to be had in the mid level price brackets. It is just a case of doing your research once you have an estimate of how much you are willing to pay. There is one thing that can be said about BJJ fanatics is that they love to discuss the sport and there a plenty forums out there with knowledgeable and opinionated practitioners who often provide very thorough Gi reviews.

With the higher price Gis, although you should of course expect a high standard of quality, you may be paying the extra for things like the brand name, additional patches or detailed embroidery and design features.

IBJJF Legal

The International Brazilian Jiu Jitsu Federation is the renowned for organising some of the word's biggest BJJ Tournaments, such as the World Jiu Jitsu Championship and Nogi World Jiu Jitsu Championship to name but a few. 

If you are looking to compete in an IBJJF tournament, you will need to be aware of the strict rules that are in place with regards to Gi specifications for competitors. 

The IBJJF has the authority to change their rules at any given time so we advise keeping yourself up to date via their official website, where you will find the necessary information on their IBJJF Uniform Requirements page.
