How to Choose Your BJJ Kimono: Complete Guide to Sizes, Fabrics, and Buying Tips
How to choose the right BJJ kimono the first time
Choosing the wrong BJJ kimono is one of the most costly mistakes a practitioner can make: a size too large that flaps around on the mat, a fabric that shrinks two sizes after the first wash, or a gi rejected at an IBJJF tournament inspection. This happens when you buy without knowing what to look for.
In this guide, you'll find everything you need to make the right choice — whether you're a white belt buying your first gi or a purple belt looking for the ideal competition gi.
BJJ Gi Fabrics: Pearl Weave, Single Weave, and Gold Weave Compared
The type of fabric is the first element to consider. Each weave has different characteristics in terms of weight, durability, and breathability. Here's a direct comparison:
|
Fabric |
Weight (gsm) |
Pros |
Cons |
Ideal for |
|---|---|---|---|---|
|
Pearl Weave |
400–550 |
Lightweight, quick-drying, grip-resistant |
Less robust than double weave |
Daily training and competitions |
|
Single Weave |
350–450 |
Economical, lightweight, breathable |
Less resistant to aggressive gripping |
Beginners, warm climates |
|
Double Weave |
600–800 |
Very durable, hard to grip |
Heavy, slow to dry |
Intense training, not for competitions |
|
Gold Weave |
500–600 |
Balance of weight/durability |
More expensive |
Intermediate/advanced athletes |
|
Ripstop |
300–400 |
Very lightweight, anti-abrasion |
Less traditional |
Summer, hybrid no-gi |
For most practitioners, a 450 gsm pearl weave gi is the perfect balance: light enough not to weigh you down during a summer training session, robust enough not to fray under continuous guard grips.

⚠ ATTENTION TO SHRINKAGE |
Competition Gi: What the IBJJF Rules Say
If you participate in FIJLKAM/IBJJF tournaments, your gi must meet specific requirements. Failing to meet them means disqualification at the mat — and I assure you it happens more often than you think:
-
Color: only white, blue, or black. No grey, camo, or burgundy.
-
Sleeve length: max 5 cm from the wrist with the arm extended.
-
Pants length: max 5 cm from the ankle.
-
IBJJF label: the IBJJF patch must be present on the left shoulder.
-
Patches and emblems: allowed, but must not cover designated areas.
In our selection of BJJ Kimonos on TopKimono, you'll find all gis with clear IBJJF approval indicated on the product page. No surprises at weigh-in.
Which Kimono to Choose Based on Your Skill Level
White belt — first gi
Don't overspend on your first gi: you'll ruin at least one in the first 6 months (we've all been there). Look for a light single weave or pearl weave, white or blue (academies often require it), and a generous size. The Tatami Nova Absolute is the benchmark for value in this range.
Blue/purple belt — advanced training
At this level, you already know you spend 4-5 times a week on the mat. The gi needs to last. Aim for a 450-550 gsm pearl weave, possibly a double gi (one light for competitions, one dark for intense training sessions). Kingz kimonos on TopKimono are designed exactly for this use.
Competitive athlete — competition gi
Weight and tailored fit make a difference when competing. A lighter gi brings you closer to the next weight category, keeping you in yours. Look for IBJJF approved products, with ripstop or ultra-light pearl weave fabric. Explore our competition section on TopKimono for competition-ready options.
How to Care for Your BJJ Gi: Tips Not Found on the Label
-
Wash immediately after each training session: don't leave a wet gi in your bag. Bacteria proliferate in 2 hours.
-
30°C, gentle spin, inside out: the three golden rules for not ruining embroidery and colors.
-
Never tumble dry: heat irreversibly shrinks cotton fibers.
-
Hang dry in the shade: sun fades color in a few weeks, especially on blue.
-
Never bleach: it destroys the fibers. Use OxiClean or baking soda for stubborn whites.
Conclusion: The Right Kimono Starts with the Right Choice
Choosing the correct BJJ kimono isn't just about aesthetics — it affects your performance, your competitive longevity, and compliance with regulations. The wrong size, too heavy fabric, or a non-approved gi can cost you lost training hours or disqualification at a tournament.
Now you know exactly what to look for. The next step is to find it.
