BJJ Equipment Guide UK | Gi, No Gi & Beginner Essentials

The Complete BJJ Equipment Guide

Intro

Starting Brazilian Jiu-Jitsu can be confusing if you are unsure what equipment is actually required. This guide explains the difference between gi and no gi gear, what beginners should buy first and how to choose BJJ clothing and accessories that are comfortable, durable and suitable for regular training.

Who this guide is for

This guide is for:

  • beginners joining their first BJJ class
  • grapplers moving between gi and no gi
  • parents buying junior BJJ gear
  • athletes upgrading their current training kit

Section 1: What gear is needed for gi BJJ

For gi training, the essentials usually include:

  • BJJ gi
  • belt
  • rash guard under the gi if preferred
  • mouthguard
  • kit bag

Section 2: What gear is needed for no gi

For no gi training, the core items are:

  • rash guard
  • grappling shorts or spats
  • mouthguard
  • optional knee support depending on preference

Section 3: How a BJJ gi should fit

A good gi should allow free movement while remaining secure and academy-appropriate. It should not be excessively baggy or restrictive, and sleeve and trouser length should be checked against your gym or competition requirements.

Section 4: Rash guards and grappling clothing

Rash guards help with comfort, hygiene and mat burn protection. Choose one that fits securely without bunching or riding up excessively.

Section 5: Belts and progression

BJJ belts reflect rank and should match your academy requirements. For beginners, the correct starting belt is usually determined by the gym and age level.

Section 6: What beginners should buy first

If you are just starting out:

  • ask whether your class is gi or no gi
  • buy only the essentials first
  • prioritise fit, comfort and durability

Section 7: Common mistakes

  • buying a gi without checking academy rules
  • turning up to no gi class in unsuitable gym wear
  • ignoring mouthguards
  • choosing fashion over durability

Section 8: Recommended categories to shop
