Picture this: you have finally booked that first no-gi class. Your bag is by the door. Then you look at your old gym shorts, notice the pockets, and wonder whether everyone else knows something you do not.
That small moment can make a new room feel even more intimidating. You do not need a perfect outfit to belong there. You need clean, suitable kit that lets you focus on learning.
The simple starting point: a fitted rash guard, pocket-free grappling shorts, appropriate underwear, sandals for off the mat, and water. Ask your gym what it requires before your first visit. Bring a properly fitted mouthguard if you already use one, and ask your coach about its use for the session.
Start with your gym, not your shopping basket
Send the coach one short question: “What should I wear to my first no-gi class, and do you have any uniform requirements?” Some clubs have specific kit rules or loaner gear. Others will allow suitable athletic clothing for an introductory session.
That answer can save you buying the wrong thing. You can build a larger kit once you know your training schedule.
A rash guard that moves with you
A rash guard is a close-fitting training top. Compared with a loose cotton T-shirt, it leaves less fabric hanging around during grappling and is designed for movement. Long sleeves give more skin coverage; short sleeves leave your forearms uncovered. Choose the option that feels comfortable and meets your club’s rules.
Try reaching overhead, twisting, and sitting into a squat. The top should stay reasonably in place without making it difficult to breathe or restricting your shoulders. There is no universal “one centimetre of loose fabric” test: use the product’s size chart and check how it feels in motion.
If you are choosing your first one, browse the BJJ rash guard collection with your measurements beside you. Coverage is not a substitute for clean equipment or your gym’s hygiene practices.
Shorts: check the details before the design
Start with BJJ shorts that have a secure waist, room to move, and no exposed hard fasteners. Open pockets can catch fingers or toes, so pocket-free shorts are the straightforward choice for grappling.
Do a quick movement check at home: squat, lift a knee, and sit with your knees drawn toward your chest. Watch for a waistband that slides, fabric that pulls across the hips, or a hem that gets in your way. Fit varies between cuts; your usual clothing size is only a starting point.
Some MMA shorts work well for no-gi too. Judge the actual pair by its construction and your gym’s rules. “Board shorts” is not an automatic verdict either way: pockets, closures, fit, and the applicable rules matter more than the label.
What goes underneath?
Wear suitable underwear that stays in place. Compression shorts or BJJ spats are optional layers for everyday training if your gym allows them. Some people like the extra coverage; others prefer fewer layers.
Do not assume every gym or competition permits the same combination. Ask whether shorts must be worn over spats, and check the rules for your division if you plan to compete.
The small things you will be glad you packed
- Sandals: for walking away from the mat. Follow the gym’s footwear rules.
- Water: bring your own bottle and check where drinks are allowed.
- A change of clothes: especially if you are travelling home after class.
- A separate bag for used kit: unpack it when you get home and wash according to the care labels.
Remove jewellery before training and check your fingernails and toenails. If you are unsure whether a piece of equipment is appropriate, show the coach before the session begins.
Training clothes and competition clothes are different decisions
A colourful training set is not automatically competition approved. The IBJJF uniform requirements, for example, specify rash guard colours and coverage, plus shorts requirements that depend on the division. Other organisers can have different rules.
Check the current event guidance before purchasing competition kit. Do not rely on a product name or a general blog checklist as an approval guarantee.

Quick questions before you go
Can I wear a T-shirt for my first class?
Ask your gym. Some allow a suitable T-shirt for an introduction; a fitted rash guard is often more practical for regular grappling. Avoid assuming every club has the same policy.
Do I need to buy three complete sets?
No. Start with enough clean kit for your actual schedule and laundry routine. Add another set when training frequency makes it useful.
Do I need a belt for no-gi?
You normally do not wear a gi belt during no-gi training, though your gym may have rank-related clothing requirements. Ask before buying.
You already did the difficult part by booking the class. Pack the basics, arrive a little early, and let the coach help with the rest.
