The gi (or kimono) refers to the heavy pajama-like training outfit worn for some grappling arts. In most judo classes, and some Brazilian jiu-jitsu classes, you will be expected to wear a gi to train in. The gi is made of heavy-duty material that can be gripped and used to control, throw or submit the opponent. This makes some techniques much easier to execute, and others more difficult.
Why use one?
Either because you want to train or compete in a style of grappling that uses the gi, or as a training tool to improve your grappling in general.
The usefulness of the gi as a training tool for those who are primarily interested in no-gi arts (MMA, wrestling or no-gi submission grappling) is a hotly debated topic. Some argue that it forces you to become more technical and helps to improve certain aspects, such as escapes. Others maintain that it is a distraction and uses valuable training time that could be put to better use. Try for yourself and make up your own mind.
JUDO GIS VS BJJ GIS
A Brazilian jiu-jitsu gi is typically tighter fitting and has a thicker, reinforced collar compared to a judo gi. Often these are actually illegal in judo competition – so make sure you are aware of the regulations for your particular sport.
Color
Judo competition gis come in either white or blue. In BJJ there are no restrictions on the color of the gi and it is common to see other colors such as black, red, yellow or even pink!
Belt
If you buy a gi, it will either come with a white belt or no belt at all. When you are graded to a different-colored belt you’ll either be given a new belt or expected to buy your own. These are easily obtained from many sports or martial arts shops.
Material
Judo and BJJ gis are made of a thick woven fabric. Don’t confuse them with karate or traditional jiu-jitsu gis, which are usually much thinner and not built to withstand all the grabbing and pulling. Traditionally, gis come in double or single weave. Single-weave gis are less expensive, lighter, cooler in summer and often more comfortable to train in, while double weave are tougher, more durable and harder for the opponent to grip. Some manufacturers have introduced other options such as gold weave (or even platinum weave), which aim to offer grapplers the best of both worlds. More expensive gis will also have additional reinforcement in areas such as knees and elbows, which take a lot of wear and tear. In terms of durability, you typically get what you pay for.
GENERAL TIPS
Getting the right size
Most suppliers and manufacturers will tell you the size of gi you need, based on your height. Usually this is about right. If you are trying one on in a shop, bear in mind that most will shrink when you first wash them. How much they shrink will depend on the brand – so check with the person selling you the gi, or with someone else who has bought the same brand in the past.
For competition, some organizations have rules about the size of your gi. In judo, for example, the sleeves and trousers must be a certain length and allow a certain amount of slack that can be gripped.
Washing your gi
Most gis need to be washed at a cool temperature. Never make the mistake of washing a white gi with colored clothes.
If you train more than once a week you’ll probably find it convenient to have at least two gis – one to wash and one to wear. Double-weave gis, especially, can be frustratingly slow to dry. Avoid the temptation to speed things up by using a tumble dryer, unless you are very confident that your gi is shrink proof (most aren’t).
