I finally picked up a new pair of raja thai boxing shorts last month, and honestly, they've completely changed how I feel during my morning pad work sessions. If you've spent any time in a Muay Thai gym, you know that the gear you wear isn't just about looking the part—it's about not having your clothes get in the way when you're trying to throw a high kick or navigate a clinch. Raja is one of those brands that just gets it right without trying too hard to be "modern" or "high-tech."
There is something inherently classic about the way Raja designs their gear. They've been around the Bangkok scene for a long time, and you can feel that history in the fabric. While other brands are moving toward sublimated graphics and weird stretchy materials, Raja mostly sticks to what works: high-quality satin, thick waistbands, and that iconic "retro" cut that makes everyone's legs look a little more dangerous than they probably are.
Why the retro cut actually matters
When I first started training, I didn't think much about the shape of my shorts. I just bought whatever was on sale. But after wearing raja thai boxing shorts, I realized that the "retro" or "short-cut" style isn't just a fashion choice. These shorts are designed with a wider leg opening and a shorter length, which is a lifesaver when you're working on your flexibility.
You don't want your shorts catching on your thighs when you're throwing a roundhouse kick. I've had cheaper shorts from generic sports brands that actually restricted my movement because the fabric didn't have enough "give" or the side slits weren't high enough. Raja solves this by making the leg holes quite flared. It feels airy, it stays out of the way, and it allows for a full range of motion. Plus, let's be real, showing off a bit of quad muscle makes you feel like you've actually been doing your roadwork.
The waistband situation
Let's talk about the waistband, because it's usually the first thing people notice. Raja uses a traditional multi-stretch elastic waistband that is, quite frankly, pretty beefy. It's got about six or seven rows of stitching. At first, it might feel a little stiff—maybe even a bit "crunchy"—but after a couple of washes and a few sweaty sessions, it breaks in beautifully.
The great thing about this thick waistband is that it stays exactly where you put it. There's nothing more annoying than having to pause a sparring round to pull your shorts up because the elastic is weak. With Raja, once they're on, they're on. I also find that the thickness of the band provides a little bit of a "tucked in" feeling for your core, which I personally like when I'm moving around a lot.
Sizing can be a bit of a headache
If there's one thing that trips people up when buying raja thai boxing shorts, it's the sizing. Since these are made in Thailand, they follow Thai sizing standards, which are let's say, "optimistic" compared to Western sizes.
If you usually wear a Medium in US gym shorts, don't even look at the Medium Raja shorts unless you're planning on giving them to your younger sibling. You'll likely need an XL or maybe even a 2XL. I'm a fairly average-sized guy, and I usually have to size up twice to get a fit that doesn't feel like it's cutting off my circulation. Always check the centimeter measurements if the shop provides them. It's better to have them a little loose and use the internal drawstring than to have them so tight you can't breathe.
Durability and the "Wash Test"
I'm pretty lazy when it comes to laundry. I know the "official" advice is to hand wash your Muay Thai gear and hang it to dry in the shade of a sacred Bodhi tree, but I usually just toss mine in the machine. Despite my lack of care, my raja thai boxing shorts have held up remarkably well.
The satin they use is thick. It doesn't get that "pilly" texture that cheaper nylon shorts get after a few trips through the wash. The embroidery is also top-notch. Raja is famous for their heavy, detailed patchwork. Even after dozens of washes, the threads haven't started pulling or fraying.
One tip though: do not put them in the dryer. The heat will absolutely murder the elastic in the waistband and might even shrink the satin. I just hang mine over the back of a chair or on a drying rack, and since they're satin, they're usually bone-dry within a few hours anyway.
The aesthetic appeal
We have to talk about the looks. Raja shorts are famous for being some of the most beautiful in the game. They do these incredible color combinations—deep forest greens with gold trim, vibrant maroons with silver embroidery, and classic black with bold Thai lettering.
There's a certain prestige to the Raja logo. It's not as "mainstream" as Fairtex or Venum, so when you see someone wearing Raja in a gym outside of Thailand, it usually suggests they know their stuff. It's a "trainer's brand." It's the kind of gear you see the grizzled Kru wearing while he's holding pads and yelling "TEEP!" at you for an hour.
Satin vs. Nylon
Raja mostly sticks to satin, which is my preferred material. Nylon shorts are lighter and cheaper, but they tend to get transparent when you're sweating buckets, and they don't have that "snap" when you move. Satin has a bit of weight to it—it feels like a piece of equipment rather than just a piece of clothing. It also holds the shape of the flares better, which is key for that classic Muay Thai silhouette.
Comparing Raja to the "Big Two"
Most people usually choose between Fairtex, Twins, and Raja. While Fairtex tends to have a more "slim-fit" and modern feel, and Twins is known for being super heavy-duty, Raja sits right in the middle. I find Raja shorts to be more comfortable than Twins because they aren't quite as bulky, but they feel more "authentic" than the newer Fairtex designs.
If you have thicker thighs, raja thai boxing shorts are probably going to be your best friend. The way they flare out at the bottom is much more forgiving for people with a "leg day" physique than the straighter cuts you see from other brands.
Wrapping it up
At the end of the day, you're going to be sweating, bleeding, and probably crying a little bit in these shorts, so you might as well like how they feel. Raja has managed to keep that old-school Bangkok charm while making gear that actually survives the rigors of modern training.
They aren't the cheapest shorts on the market, but they aren't overpriced either. For the level of craftsmanship you get—especially that heavy-duty embroidery—they're a steal. If you're tired of generic-looking gear and want something that feels like it has a bit of soul (and gives your kicks the room they need to breathe), you really can't go wrong with a pair of Raja shorts. Just remember: size up. Trust me on that one. Your waistline will thank you.
