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.

Designed for fighters who live on the mat, the Fairtex BJJ2 Matchanu Premium BJJ Gi in Navy is a heavyweight cotton kimono built for serious roll time. Crafted from a single-weave pearl cotton, this Gi takes a beating without losing its structure and breaks in beautifully session after session.
The reinforced collar holds shape against repeated grip attacks, while the ripstop pants hold up to knee-on-belly pressure and scrambles. Subtle Matchanu artwork on the inner lapel pays tribute to the Thai mythological serpent.
Main Features:
- Single-weave pearl cotton construction with long-term durability
- EVA-reinforced collar that resists collapse from gripping
- Ripstop trousers with knee reinforcement for heavy ground work
- Handmade in Thailand for authentic craftsmanship
