Quick Answer: Wear fitted athletic clothing like a rash guard or snug t-shirt with board shorts or compression pants—no gi needed for your first class. Avoid loose clothing, zippers, buttons, and jewelry. You'll train barefoot, so bring flip-flops to and from the mat. Most importantly, wear something comfortable that lets you move freely.
For your first jiu jitsu or MMA class, wear fitted athletic clothing you can move in — a rash guard or plain t-shirt with board shorts or athletic pants with no pockets, zippers, or buttons. Martial arts training attire is any clothing that stays close to the body, won't snag on a partner, and lets you move through a full range of motion without restriction. You don't need to buy a gi or any special gear before your first session. This FAQ covers every clothing question adults ask us before stepping onto the mat, so you can show up focused on training instead of worrying about your outfit.
No. Most schools, including ours, don't expect you to own a gi on day one. A gi is the traditional jacket-and-pants uniform used in jiu jitsu, but purchasing one before you've even tried a class is unnecessary. We'll let you know when it's time to invest in one — and we'll help you pick the right size and brand when you're ready.
A fitted rash guard is ideal, but a snug-fitting t-shirt works fine for your first class. Avoid loose or baggy shirts — they ride up during groundwork, get grabbed by training partners, and generally get in the way. Cotton t-shirts are okay for one session, though they absorb sweat fast and get heavy. If you decide to keep training, a basic rash guard is usually the first piece of gear worth buying.
Athletic shorts without pockets or zippers are your safest bet. Basketball shorts with side pockets tend to catch fingers and toes during grappling, which can cause minor injuries to you or your training partner. Board shorts — the kind you'd wear surfing around Imperial Beach — actually work surprisingly well because they sit close to the body and are built to handle movement and moisture.
If your shorts have a drawstring, tuck it inside the waistband so it doesn't come loose during drills.
Absolutely. Compression pants or athletic leggings are one of the best options for a first class. They stay in place, they don't have anything that can snag, and they give you full range of motion for hip escapes, guard work, and takedown drills. Many experienced students train in compression pants under their gi or shorts year-round.
A few things create problems on the mat:
You'll train barefoot on the mat. Bring flip-flops or slides to wear between the changing area and the training area — walking barefoot off the mat and then stepping back on tracks dirt and bacteria onto the training surface. This is a basic hygiene practice every martial arts school follows, and it's one of the first habits you'll pick up.
Yes. Bring a clean shirt and a change of clothes for after class. You're going to sweat — a lot. Having something dry to change into makes the drive home through Imperial Beach or up the 5 much more comfortable. A small towel and a plastic bag for your wet training clothes are smart additions to your gym bag.
For your very first class, you typically won't need a mouthguard. Introductory sessions focus on fundamental movements and technique rather than live sparring. As you progress and start rolling (live grappling), a mouthguard becomes essential. We'll tell you exactly when that transition happens so you can be prepared.
The CDC's guidance on mouthguard use in contact sports recommends properly fitted mouthguards for any activity involving potential contact to the face — good advice once you're sparring regularly.
It matters enough to think about for five minutes, but not enough to stress over. The goal is comfort and safety — yours and your training partner's. Our coaching staff works with adults every day in 2026 who walk in wearing a t-shirt and running shorts and do just fine. Nobody on the mat is judging your outfit. They're focused on their own training.
Our approach to welcoming new students is something most schools don't offer — we walk you through everything before class starts, including what to wear next time if something didn't work well today. Customer service isn't an afterthought here. It's built into the experience from the moment you reach out.
Come in for a free VIP tour or trial class and see for yourself. You'll meet the coaches, see the training space, and get a feel for the community before you ever step on the mat. Just show up in something you can move in — we'll handle the rest.
