Walking onto the competition mats for the first time is exciting—but it can also be stressful. The last thing you want is to arrive at the venue only to discover your gi doesn’t meet the requirements, you’ve forgotten an essential item, or your rashguard isn’t legal for your division.
Whether you’re competing in an IBJJF tournament, a local event, or your first white belt competition, having the right gear removes unnecessary stress so you can focus on your performance.
This guide covers everything you need to compete with confidence.
Why competition gear matters
Competition gear isn’t just about looking professional. It directly affects:
- Comfort during long tournament days
- Confidence before stepping onto the mat
- Compliance with tournament rules
- Performance during matches
- Recovery between fights
Many competitors spend months preparing physically but overlook their equipment until the night before. Don’t make that mistake.
Gi competitions: essential gear checklist
For gi tournaments, you’ll need:
Competition-legal gi
Your gi should:
- Fit the tournament’s sizing regulations
- Be free from tears or excessive wear
- Have properly placed patches (where allowed)
- Be clean and freshly washed
- Be one of the approved colors for your organization
Most organizations accept white, blue and black. A lightweight pearl weave gi is the preferred choice for many competitors because it offers an excellent balance between durability, comfort, and reduced weight during weigh-ins.
Pro tip: Always bring a second gi if you own one. Sweaty gis become uncomfortable throughout the day, and accidents happen. Having a backup can save your tournament.
Competition belt
Your belt should:
- Match your official rank
- Be in good condition
- Stay tied securely
- Meet tournament requirements
A frayed belt isn’t necessarily illegal, but it’s always better to compete with one that’s clean and presentable. If you compete at IBJJF competitions, a belt that shows wear can’t be used. If you can’t get a new belt in the time given, you will be disqualified.
Rashguard
Even in gi divisions, if the organization allows it, many athletes wear a rashguard underneath. Benefits include reduced skin irritation, better sweat management, increased comfort and less friction during long matches. Choose a moisture-wicking rashguard with flatlock stitching for maximum comfort.
Mouthguard
Even when it’s optional, wearing a mouthguard helps protect your teeth during scrambles, takedowns, and accidental collisions. A custom-fit mouthguard offers the best comfort and protection.
No-gi competition gear
No-gi has its own requirements.
Ranked rashguard
Many organizations require rashguards that correspond to your belt rank. Typical colors include white, blue, purple, brown and black. Always check the event’s rules before ordering a rashguard.
Grappling shorts
Your shorts should have no pockets, no exposed zippers, no metal parts, and allow unrestricted movement. The best grappling shorts feature four-way stretch fabric, reinforced stitching, a silicone waistband or internal drawstring, and lightweight construction.
Compression shorts or spats
Compression wear provides muscle support, reduced chafing, improved comfort and better hygiene. Many athletes wear compression shorts underneath their grappling shorts for extra security.
Don’t forget these essentials
Competition day is long. Pack:
- Water bottle
- Electrolyte drink
- Easy-to-digest snacks
- Flip-flops
- Small towel
- Nail clippers
- Athletic tape
- Finger tape
- Extra mouthguard, rashguard and belt
- Deodorant
- Plastic bag for sweaty gear
- Toilet paper
Having everything organized in your gym bag keeps tournament mornings stress-free.
Check your gi before leaving home
One of the most common reasons competitors are disqualified before their first match is failing the gi inspection. Before leaving, make sure:
- Gi has been washed and has fully dried
- Belt is packed
- Sleeves and pants fit correctly
- No ripped seams or loose stitching
- No forgotten patches
Never assume your gi still fits after washing. Cotton shrinks over time.
Should you buy a lightweight competition gi?
For most competitors, yes. Advantages include easier weight cuts, staying cooler during matches, faster drying, and more comfort between rounds. Many competition-specific gis weigh significantly less than everyday training gis while still meeting tournament regulations.
How many gis should competitors own?
If you compete regularly, two or three gis is ideal — for example, one daily training gi, one dedicated competition gi, and one backup gi. Keeping a separate competition gi helps preserve its fit and appearance.
Common competition gear mistakes
Avoid these mistakes:
Buying a gi without checking tournament rules
Not every gi is legal for every organization.
Wearing a brand-new gi on competition day
Always train in your competition gear first. You’ll discover fit issues before they matter.
Forgetting your belt
It happens more often than you’d think. Pack it the night before.
Not washing your gear
Nothing is worse than competing in yesterday’s sweat. Always arrive with clean gear.
Cutting weight without testing your gi
A freshly washed gi may shrink enough to fail inspection. Check your fit well before tournament day.
