Fairtex BJJ Gi Size Guide
Fairtex BJJ Gis use the standard adult A0–A3 sizing convention. The measurements below are flat-garment dimensions in inches. Pick by height first, then check chest and waist — a Gi that's too short will ride up during rolls, and one that's too loose will be easy to grip.
Jacket
| Size | Chest (in) | Jacket length (in) | Sleeve (in) |
|---|---|---|---|
| A0 | 22 | 31 | 28 |
| A1 | 23 | 32 | 28 |
| A2 | 24 | 33 | 29 |
| A3 | 26 | 35 | 30.5 |
Pants
| Size | Waist (in) | Pant length (in) | Inseam (in) |
|---|---|---|---|
| A0 | 20 | 37 | 29 |
| A1 | 20.5 | 38 | 30 |
| A2 | 21.5 | 40 | 30.5 |
| A3 | 23 | 41.5 | 31 |
How to measure
- Chest — measure around the fullest part of your chest, under the arms, keeping the tape level.
- Waist — measure around your natural waistline.
- Sleeve length — from the centre back of the neck, over the shoulder, down to the wrist with the arm slightly bent.
- Pant inseam — from the crotch seam down to the floor.
- Quick rule — if you're between sizes, the larger size is usually safer for BJJ because Gis shrink slightly after the first few washes.

Description
Hand-finished in Thailand, the Fairtex BJJ3 Treeburam Premium BJJ Gi in Black is a single-weave pearl cotton kimono engineered for fighters who roll daily. Crafted from durable cotton with reinforced stress points, this Gi holds shape through years of grips, sweeps, and scrambles.
The EVA-reinforced collar fights collapse under heavy grip pressure, while the ripstop pants reinforce the high-wear knee zone for ground work. Subtle Treeburam artwork on the inner lapel honours the Thai mythological lion.
Main Features:
- Single-weave pearl cotton built for hard, daily roll time
- EVA-reinforced collar that resists grip collapse
- Ripstop trousers with reinforced knees for ground work
- Handmade in Thailand for authentic craftsmanship
- IBJJF-friendly cut suitable for both training and competition
