Judo Gi NZ Guide: How to Choose the Best Judo Uniform in New Zealand

Choosing the right judo gi in NZ is essential for safety, comfort and performance on the mat. A quality judo uniform should fit well, withstand gripping and throwing, and match the needs of beginners, kids, regular club members, and competitors. This guide explains everything you need to know about judo gi sizing, weave types, durability and which judo uniforms work best for New Zealand practitioners.

Quick Answer / TL;DR

The best judo gi for most NZ practitioners is a well-fitted cotton gi with reinforced stitching. Beginners often start with a single weave judo gi, while adults and competitors benefit from a stronger double weave judo gi. Choose a size based on height, avoid overly baggy fits, and wash in cold water to prevent shrinkage.

1. What Is a Judo Gi and Why It Matters

A judo gi (judogi) is a two-piece uniform designed for gripping, throwing and ground control. Unlike karate or taekwondo uniforms, a judo gi uses a thick weave and reinforced stitching to handle heavy pulling. In NZ clubs, the right judo uniform improves safety, makes training more comfortable, and ensures you meet club and competition standards.

Safety: prevents tearing during throws and grips
Durability: handles intense grappling
Performance: improves control and movement
Compliance: matches NZ club and grading expectations

2. Key Factors When Choosing a Judo Gi in NZ

2.1 Material & Weave Types

The weave is the biggest factor in choosing a judo uniform in New Zealand.

Single Weave Judo Gi (Best for Beginners & Kids)

Lightweight and easy to move in
Affordable entry-level option
Ideal for younger judoka
Not as durable as double weave

Double Weave Judo Gi (Best for Adults & Competitors)

Much stronger and harder to grip
Durable for heavy training
Preferred for competition
Feels heavier and stiffer

2.2 Judo Gi Sizing

Judo gi sizing is based mainly on height. A well-fitted gi allows full movement without excess fabric.

Sleeves should reach the wrist bone
Pants should reach the ankle bone
The jacket must cover the hips
Avoid overly tight or tailored fits

Kids may need a slightly larger size for growth, but avoid excessively oversized uniforms — they are unsafe and frustrating to train in.

2.3 Reinforcement & Durability

Look for a judo gi with:

Reinforced knees
Heavy stitching
Strong collar
Sturdy shoulder seams
