GI: equipment for BJJ, judo and kimono training

GI is the training uniform used in martial arts and combat sports where athletes work with fabric grips – most notably Brazilian jiu-jitsu (BJJ) and judo. In this category you will find BJJ Gi, Judo Gi and belts for children and adults, beginners and experienced athletes alike.

Choosing the right GI affects comfort, freedom of movement, grip durability and the overall training experience. Quality material, reinforced stitching and the right cut help you handle technical drilling, sparring and regular club training with ease.

What does the GI category include?

BJJ Gi: kimonos designed for Brazilian jiu-jitsu. Choose by size, cut, weight, design and intended use – from your first class to full competition prep.
Judo Gi: durable gi for judo, built for the throws, techniques and powerful grips that define the sport.
Belts: belts for BJJ, judo and other combat sports in a variety of lengths, colours and styles.

How to choose the right GI?

Size: The GI should fit well according to your height and weight. An oversized kimono gets in the way; one that is too small restricts movement.
Cut: Some gis feature a slimmer athletic cut, others are cut wider for everyday training comfort.
Weight: A lighter gi is more comfortable and dries faster; a heavier gi can offer greater durability under frequent use.
Material: Cotton or blended performance fabrics are the most common choices for regular training.
Purpose: Different gis suit recreational training, intense sparring or competition – choose accordingly.

BJJ Gi vs. Judo Gi: what is the difference?

BJJ Gi and Judo Gi may look similar at first glance, but they are designed for different disciplines. The BJJ Gi is tailored to the techniques of Brazilian jiu-jitsu, ground work and prolonged contact with an opponent. The Judo Gi is built for judo, where fabric grips, pulling and dynamic throws are central to the sport.

Our recommendation is to choose based on the sport you actually train. If you practise BJJ, shop the BJJ Gi category. If you do judo, go with a Judo Gi.

GI or kimono?

In everyday speech the word kimono is often used, while in the BJJ and judo community the term GI is equally common. Shoppers frequently search for BJJ Gi, Judo Gi, BJJ kimono or judo kimono. This category covers all of these needs.

How to choose a belt?

A belt indicates the athlete's technical level and keeps the GI in place during training. The right length, colour and type depend on the specific sport. Belt ranking systems differ between BJJ, judo and other martial arts.

If you are unsure about the length, follow the manufacturer's recommendation or measure your waist circumference over a worn GI. The belt must be long enough to tie securely without getting in the way during training.

Who is a GI suitable for?

GI suits children, adults, beginners and seasoned competitors. Beginners appreciate a comfortable fit and straightforward size selection; advanced athletes often look closely at weight, durability, cut, competition regulations and long-term performance under heavy training loads.

How to care for a GI?

To extend the life of your gi, wash it according to the manufacturer's instructions – typically at low temperatures and without fabric softener. Fabric softener can degrade the material's properties. Air drying is recommended; avoid tumble dryers unless the manufacturer explicitly states otherwise.

After training, do not leave the GI sealed in your bag. Regular airing and proper washing reduce odour, keep the material in better condition and extend the lifespan of the whole kit.

Find the right GI for your sport

Whether you are starting Brazilian jiu-jitsu, training judo or looking for a new belt – the GI category has the core equipment for kimono training. Choose BJJ Gi, Judo Gi or belts by sport, size and intended use.
