BJJ Gi's

At a glance: A BJJ gi is your essential uniform for Brazilian Jiu Jitsu training, available in sizes from Y00 (toddler) through A5 (extra-large adult). This collection includes lightweight 350–380 gsm options for speed and mobility, mid-weight 450 gsm gis for durability, and beginner-friendly models that include a white belt. Half sizes (A1.5, A2.5, A3.5) ensure a precise fit.

Choosing the right BJJ gi for your level

If you're new to Brazilian Jiu Jitsu, look for an entry-level gi that balances affordability with durability. The Venum First series is designed for beginners and includes a white belt, so you can step onto the mat immediately. These gis use a lighter weave that's easier to break in and comfortable during your first months of training.

Intermediate and advanced practitioners benefit from heavier constructions such as 450 gsm pearl weave, which withstand constant drilling and sparring. The Venum Elite 5.0 and Contender 3.0 offer reinforced stitching at stress points and a tighter fit that gives opponents less fabric to grip. Competition-level gis meet IBJJF regulations for weave thickness, patch placement and jacket length.

Understanding BJJ gi sizes and fit

BJJ gis use alphanumeric sizing: A0 through A5 for adults, Y00 through Y4 for children. Each size corresponds to a height and weight range, but manufacturers' charts vary by brand. Half sizes (A1.5, A2.5, A3.5) suit athletes who fall between standard sizes or prefer a tailored fit. An A1L accommodates taller, leaner builds.

Pre-shrunk gis maintain their size after washing, while untreated cotton can shrink up to one size. Always check the product description for shrinkage guidance. The jacket should reach mid-thigh, sleeves must stop no more than 5 cm from the wrist, and trousers should end above the ankle bone when you're standing. A gi that's too large gives grips; one that's too small restricts movement and may tear.

Materials and weave types explained

The jacket weave determines weight, durability and comfort. Single weave (350–380 gsm) is lightweight and dries quickly, ideal for hot climates or fast-paced training. Pearl weave (400–450 gsm) offers the best balance: it's durable, breathable and lighter than double weave, making it the most popular choice for year-round use.

Trousers are typically ripstop or twill cotton with reinforced knees. Ripstop construction uses a grid pattern that prevents tears from spreading. Look for reinforced stitching at the collar, armpits, knees and crotch—these areas endure the most stress during rolls. Pre-shrunk cotton simplifies care and ensures consistent sizing.

Pairing your gi with the right gear

A BJJ gi is only part of your training kit. Many athletes wear BJJ shorts or leggings underneath for hygiene and comfort during no-gi sessions. Rashguards protect your skin and wick moisture. Check your academy's uniform policy before your first class—some schools require a white gi, while others allow any colour.

Frequently asked questions

Which BJJ gi is best for beginners?

The Venum First series is ideal for beginners because it includes a white belt and uses a lighter weave that's comfortable during your first months of training. Entry-level gis such as the Contender 2.0 offer good durability at an accessible price point. Look for a single or light pearl weave (350–380 gsm) that's easier to break in than heavier competition gis. Make sure the gi meets your academy's colour requirements before you buy.

What size BJJ gi should I buy?

Measure your height and weight, then consult the manufacturer's size chart—every brand fits slightly differently. Standard sizes run from A0 to A5 for adults and Y00 to Y4 for children. Half sizes (A1.5, A2.5, A3.5) suit those between standard sizes. The jacket should reach mid-thigh, sleeves must stop within 5 cm of your wrist, and trousers should end above the ankle. If the gi is not pre-shrunk, order one size larger to account for shrinkage.

How do I care for my BJJ gi?

Wash your gi after every training session in cold water to prevent shrinkage and colour fading. Hang it to air-dry rather than using a tumble dryer, which can shrink the fabric and weaken stitching over time. Avoid fabric softener, as it reduces the cotton's ability to absorb sweat and can leave a slippery residue. Pre-shrunk gis are easier to care for because they maintain their size through repeated washing.
