In short: 12 November 1993, Denver. A 80 kg / 176 lb Brazilian in a gi beat three heavier men in one night and won the first UFC tournament. Royce Gracie had just put Brazil into combat sports history. Solid green shorts with the Brazilian flag on the left leg, Muay Thai cut. 8 sizes, XS to 4XL. €39 in XS, €44 from S to 4XL.
The night Brazil changed combat sports
Denver, 12 November 1993. An American tournament with no weight classes and no rounds set out to find which martial art actually worked. Against boxers, a sumo wrestler and karateka, a lean Brazilian in a white gi won three fights in one evening: Royce Gracie.
Brazilian jiu-jitsu had just introduced itself to the world, and the UFC had been born. Thirty years on, no MMA fighter trains without Brazilian ground work in the toolkit. Brazil went on to give the sport Anderson Silva, José Aldo and Amanda Nunes.
Standing up, the country built its own schools too: Brazilian Muay Thai and luta livre. On a pair of fight shorts this flag is not about football — it is about the nation that has changed how people fight more than any other in thirty years.
What the shorts look like
Solid green across the whole garment, no panelling. On the left leg, the complete Brazilian flag: yellow lozenge, blue celestial globe, the Ordem e Progresso banner and the stars of the night sky. The motif sits on its own, low on the leg.
The wide elastic waistband repeats the body green. Satin finish.
The Muay Thai cut, and why it matters
Every country short in this collection shares one cut: short leg, high side split over the hip, wide elastic waistband. That is not styling. The high split clears the hip completely, which is what a head kick and a clinch need — the two movements Muay Thai is built around.
In practice these work for Muay Thai, kickboxing, K-1 and MMA training, and they are just as usable in boxing for gym work and club shows: the leg stays free and nothing catches during footwork.
Technical specifications
Worth knowing: a solid green ground with the flag set as a badge makes this the plainest treatment in the range alongside the Switzerland short, and the easiest to pair with a coloured rashguard or tee. For sanctioned amateur bouts, check the corner colour your association assigns.
Getting the size right
European cut — take your usual size. Most Muay Thai shorts on the market are Thai-made and sized accordingly, which is why almost every seller tells you to order one size up. These are cut to European sizing, so that correction does not apply. Eight sizes, XS to 4XL, where the bulk of the market stops at XXL. The elastic waistband absorbs a swing in waist measurement, which helps through a fight camp. If you train in a groin guard, go one size up.

Frequently asked questions
Do Muay Thai shorts run small?
Thai-made shorts do, which is why the usual advice is to order one size up. These are a European cut — take your usual size. Eight sizes run from XS to 4XL. Between two sizes, or if you wear a groin guard, take the larger one.
What is the difference between Muay Thai shorts and boxing shorts?
Muay Thai shorts sit above the knee with a high side split and a wide elastic waistband, which clears the hip for kicks and clinch work. Boxing shorts run longer with the waistband above the navel, marking the low-blow line. These are the Muay Thai cut, and they carry over to boxing training without trouble.
Who won UFC 1?
Royce Gracie, on 12 November 1993 in Denver, weighing around 80 kg / 176 lb against heavier opponents, submitting three men in a single night. The result is what put Brazilian jiu-jitsu on the map.
Why is Brazil so strong in combat sports?
Brazilian jiu-jitsu gave the country a ground game nobody else had when MMA began, and it built its own stand-up schools in Brazilian Muay Thai and luta livre. The line runs from Royce Gracie through Anderson Silva and José Aldo to Amanda Nunes.
How do you wash Muay Thai shorts?
Machine wash inside out at 30 °C / 86 °F, no tumble dryer, and never put an iron directly on the panels. Skip the fabric softener: it coats the weave and slows how fast sweat moves through it.
Are these unisex?
Yes. The cut is the same for men and women — only the size changes, and the range opens at XS, which is not true everywhere.
