Gear that fits your body and your training style matters more than most beginners expect. When you start throwing teeps, roundhouse kicks, and knees at full range, the wrong shorts will bind, ride up, or fall apart after a month of washing. Choosing the best Muay Thai shorts for men comes down to fabric quality, slit height, waistband hold, and how well the cut supports hip mobility — not just how they look hanging on a rack.
– Muay Thai shorts are cut wider and shorter than boxing or MMA shorts — the deep side slits are essential for high kicks and clinch work.
– Authentic Thai brands (Fairtex, Twins Special, Yokkao) are made in Thailand and sized smaller than Western brands — size up 1–2 sizes from your usual fit.
– Satin polyester is the standard fabric for competition; nylon-spandex blends are better for heavy daily training.
– Budget range: $30–$45 for entry-level, $45–$70 for mid-range and premium options with competition-grade finish.
1. What Makes a Great Muay Thai Short for Men
Not all fight shorts are created equal. A Muay Thai short is a specialized piece of equipment, and understanding what separates a good pair from a great one helps you spend money wisely — whether you are training three times a week at a local gym or competing at regional level.
Fabric and Construction
The two dominant materials you’ll encounter are satin polyester and nylon-spandex blend. Satin poly is the traditional Thai choice — lightweight, slick against skin, fast-drying, and aesthetically sharp under gym lighting. Nylon-spandex (sometimes labeled “microfiber” or “CarbonFit” in premium lines) adds stretch that supports movement without restriction, and holds up better against repeated washing and contact.
Stitching matters more than it gets credit for. Look for reinforced triple-stitching at the waistband, side slits, and inner seam — these are the stress points that fail first on cheaper pairs. Embroidery, while traditional, adds stiffness to panels if overdone; high-quality Thai brands balance embroidery detail with flexibility.
Waistband Design
A drawstring-only waistband is fine for training, but an elastic-plus-drawstring combination gives you a more secure fit during clinch work and takedown defense. The waistband should sit at the natural waist — not low on the hips like gym shorts — to keep the short positioned correctly when you raise your knees.
Slit Height and Inseam
This is the most critical spec for functional performance. Side slits on Muay Thai shorts typically run 4 to 7 inches up from the hem. A deeper slit (6–7 inches) allows maximum hip external rotation for high roundhouse kicks and teeps. A shallower slit (4–5 inches) feels more modest but restricts range of motion slightly. Inseam length generally falls between 3 and 5 inches on traditional Thai-cut shorts — short enough to stay out of the way during knee strikes.
If you train in Muay Thai shorts and are unsure what to wear underneath them, the guide on what to wear under Muay Thai shorts covers compression options and hygiene best practices.
Sizing note: Thai brands (Fairtex, Twins Special, Yokkao) use their own sizing charts that run 1–2 sizes smaller than US/EU standards. A man who wears a US Medium will typically need a Large or XL in authentic Thai sizing. Always check the brand’s waist measurement chart — do not order based on your shirt size.
– If you are between sizes, size up. A slightly looser waist is easy to tighten with the drawstring; a tight waist mid-round is not fixable.
– Inseam and slit dimensions do not scale proportionally between sizes on all brands — check per-size specs when available.
2. The 5 Best Muay Thai Shorts for Men, Ranked
The five pairs below represent a cross-section of price points, construction quality, and training use cases. Each has been evaluated on fabric, waistband, slit depth, durability, and value for money.
Fairtex BS1901 Muay Thai Shorts
Price range: $35–$50 | Made in Thailand
The Fairtex BS1901 is one of the most universally recommended entry-to-mid points in authentic Muay Thai gear. Fairtex is a Bangkok-based manufacturer with decades of presence in professional Muay Thai, and the BS1901 reflects that lineage in its construction.
Specs:
– Fabric: 100% satin polyester
– Inseam: approximately 3.5 inches
– Side slit height: 5–6 inches
– Waistband: 3-inch elastic with internal drawstring
– Closure: drawstring tie at front
The BS1901 sits at the waist rather than the hip, which keeps it stable during knee strikes and clinch exchanges. The satin finish is smooth and fast-drying. Color options are extensive — Fairtex refreshes its design catalog regularly, and you can find everything from classic black-and-gold to modern graphic prints.
Where the BS1901 earns its reputation is in durability. The stitching at the slit base — historically a failure point on cheaper shorts — holds up well through months of daily training. At the $35–$50 price point, it is one of the best value options available on Amazon for men just starting out or building a rotation of training shorts.
“Fairtex shorts are what I hand to every new student who asks what to buy. They’re authentic, they fit Thai-style, and they last. The BS1901 has been my go-to recommendation for years.” — Kru Marcus L., Muay Thai instructor with 14 years of experience
Twins Special TBS Muay Thai Shorts
Price range: $40–$55 | Made in Thailand
Twins Special (full name: Twins Special Co., Ltd.) is a Bangkok manufacturer that has outfitted professional fighters for over 30 years. The TBS line (their standard training short) is the workhorse of the catalog — less ornate than their competition shorts, but built to identical construction standards.
Specs:
– Fabric: 100% satin polyester
– Inseam: approximately 3 inches
– Side slit height: 6 inches
– Waistband: wide elastic (approximately 2.5 inches) with drawstring
– Closure: drawstring tie, reinforced waistband panel
The 6-inch slit is the standout feature here. For men who train high kicks regularly or compete, the extra slit depth makes a tangible difference in hip rotation freedom. The inseam is short even for Muay Thai standards, which keeps the short completely clear of the knee during strikes.
Twins runs slightly larger in the waist than Fairtex, which some men find easier to size without ordering samples. The waistband elastic is firm and holds position well without needing to over-tighten the drawstring. One minor note: the satin on Twins shorts has a slightly heavier hand-feel compared to Fairtex, which some fighters prefer for the added structure.
Available on Amazon in a wide variety of solid and two-tone colorways. Pairs well with Twins gloves if you are building a brand-matched kit.
Yokkao CarbonFit Muay Thai Shorts
Price range: $50–$70 | Made in Thailand
Yokkao is the premium brand in this lineup, and the CarbonFit series represents their most technically developed training short. Where Fairtex and Twins rely on satin poly, Yokkao developed the CarbonFit fabric — a nylon-spandex-polyester blend with a matte finish that behaves more like athletic apparel than traditional fight shorts.
Specs:
– Fabric: CarbonFit (nylon-spandex-polyester blend, proprietary)
– Inseam: approximately 4 inches
– Side slit height: 5 inches
– Waistband: wide elastic + drawstring, reinforced seams throughout
– Closure: drawstring with flat-lock stitching at all seams
The four-way stretch of the CarbonFit fabric changes the feel of movement compared to woven satin. There is no “snap” or restriction when you throw a teep above hip height — the fabric moves with the leg. For fighters with bigger quads or men who find traditional satin shorts binding in the thighs, the CarbonFit construction is genuinely worth the premium.
The inseam at 4 inches is slightly longer than the Fairtex and Twins options, which some men prefer for modesty or for training environments where board shorts crossover is common. The slit at 5 inches is functional if not as deep as the Twins TBS.
At $50–$70, the CarbonFit is the most expensive option in this guide. It justifies the price if you train daily and want the most technically advanced fabric construction. For beginners or occasional trainers, the Fairtex or Twins options represent better value.
Hayabusa Muay Thai Shorts
Price range: $45–$60 | Made in Thailand / international manufacturing
Hayabusa is a Canadian-headquartered brand with a strong presence in the North American market. Their Muay Thai shorts are manufactured to Thai specifications and offer a middle ground between the classic Thai aesthetic and Western sizing conventions — making them one of the easiest Thai-style shorts for Western men to size correctly.
Specs:
– Fabric: 100% satin polyester with reinforced embroidery panels
– Inseam: approximately 4 inches
– Side slit height: 5–5.5 inches
– Waistband: dual-layer elastic with drawstring
– Closure: drawstring, logo-embossed waistband
The Hayabusa sizing skews slightly closer to Western standards than Fairtex or Twins, which reduces the risk of ordering the wrong size on your first purchase. The dual-layer waistband is one of the firmest in this category — it stays put during sprawl defense and wrestling exchanges, which matters if your gym mixes Muay Thai with MMA or BJJ.
Aesthetically, the Hayabusa design language is cleaner and more minimal than the ornate embroidery on some Thai brands. If you prefer a modern gym look over traditional Thai patterns, these are among the sharpest-looking shorts in the $45–$60 range. Available on Amazon with consistent stock in the most common sizes.
Venum Classic Muay Thai Shorts
Price range: $30–$45 | International manufacturing
Venum is a Paris-founded fight sports brand with manufacturing across Southeast Asia. The Classic line is their most accessible product — priced for beginners and casual practitioners, with construction that punches above its weight class for the price.
Specs:
– Fabric: 100% satin polyester
– Inseam: approximately 3.5 inches
– Side slit height: 4.5–5 inches
– Waistband: single-layer elastic with drawstring
– Closure: drawstring, Velcro not included (drawstring only)
At $30–$45, the Venum Classic is the most budget-friendly option in this guide. The satin is lighter than Fairtex or Twins, and the waistband elastic is thinner — neither is a dealbreaker at this price point, but worth noting if you plan to train five or more days a week. For men who are trying Muay Thai for the first time or want an affordable training-only pair while they decide how serious to get, the Venum Classic is a sensible starting point.
The slit height at 4.5–5 inches is adequate for most training movements, though advanced practitioners throwing high kicks will feel a slight restriction compared to the Twins TBS or Fairtex BS1901. The Venum Classic is also available on Amazon in a solid range of colorways, making it easy to grab two pairs for a training rotation without a significant investment.
How to build a training rotation:
– Buy 2–3 pairs minimum if you train 4+ days per week. Rotating shorts extends the life of each pair significantly.
– Wash in cold water, hang dry. Machine drying degrades elastic waistbands and fades satin color faster.
– Consider one pair of satin poly (Fairtex or Twins) for sparring and pad work, and one pair of stretch fabric (Yokkao CarbonFit or similar) for bag work and conditioning rounds.
– Replace when the slit base stitching begins to fray — a torn slit during a kick can cause a fall or injury.

| Hayabusa Muay Thai | $45–$60 | Satin polyester | ~4 in | 5–5.5 in | Western-sized fit, mixed martial arts cross-training |
| Venum Classic | $30–$45 | Satin polyester | ~3.5 in | 4.5–5 in | Beginners, budget-conscious buyers |
4. How to Size Muay Thai Shorts Correctly
Getting the size right on your first order saves you the hassle of returns and the delay of waiting for replacements. Here is a straightforward approach.
Measure your natural waist — not your hip, not where your jeans sit, but the narrowest point of your torso above the hip bones. This is where Muay Thai shorts are designed to sit. Most Thai brands provide a waist measurement in inches or centimeters on their size charts; match your measurement to that chart directly.
As a general reference for Thai brands:
– Small: waist 26–28 inches
– Medium: waist 29–31 inches
– Large: waist 32–34 inches
– XL: waist 35–37 inches
– XXL: waist 38–40 inches
If you are between two sizes, go larger. If you train with a cup or compression shorts underneath (which most practitioners do — see what to wear under Muay Thai shorts for a full breakdown), factor in the additional waist bulk from the underlayer.
Western brands like Hayabusa and Venum tend to align more closely to US sizing, so a US Medium typically fits as expected. For Fairtex and Twins, a US Medium usually means a Thai Large.
5. Caring for Your Muay Thai Shorts
The investment in a quality pair of shorts is only protected if you care for them correctly. Satin polyester and nylon-spandex both respond poorly to heat — whether from a dryer or direct sunlight over extended periods.
Wash after every training session. Sweat and bacteria degrade elastic fibers and satin weave over time, and the odor becomes embedded in the waistband padding if allowed to accumulate. Cold water, gentle cycle, mild detergent — no bleach, no fabric softener on the waistband.
Hang to dry in shade or indoors. If you must dry quickly, a low-heat fan is preferable to a tumble dryer. The embroidery threads on Fairtex and Twins shorts are particularly vulnerable to heat shrinkage, which can cause puckering on the design panels.
Store flat or folded. Do not leave rolled in a gym bag — the waistband elastic compresses and loses its return strength over time if stored under sustained pressure.
A well-maintained pair of Fairtex or Twins shorts will last 18–24 months of regular training. Yokkao CarbonFit, due to the stretch fabric construction, may show wear at the seat slightly earlier under very high-frequency training, but holds color and waistband integrity longer.

1. Are Muay Thai shorts different from MMA shorts?
Yes, meaningfully so. Muay Thai shorts are cut shorter (3–4 inch inseam), made from smooth satin or stretch fabric, and have deep side slits (5–7 inches) to allow full hip external rotation for kicks. MMA shorts are typically longer (board-short style), have a more reinforced crotch gusset for grappling, and use a Velcro closure in addition to a drawstring. Using MMA shorts for Muay Thai is functional but restricts kick range; using Muay Thai shorts for ground grappling exposes too much skin for mat work.
2. Can I wear Muay Thai shorts for other martial arts or workouts?
The shorts work well for kickboxing, K-1 style competition, cardio kickboxing, and general conditioning work. The slit design and waist-high cut are not ideal for BJJ (slits catch on the gi) or heavy grappling. For general gym conditioning — bag rounds, jump rope, shadowboxing — they are comfortable and functional. If you are new to combat sports and want a primer on training structure before investing heavily in gear, the top 10 Muay Thai training tips for beginners is a useful starting point.
3. Why do Muay Thai shorts have such wide, short cuts compared to other fight shorts?
The cut is a direct product of the sport’s technical demands. Muay Thai involves a high volume of circular kicks at hip height and above, clinch work requiring free hip rotation in multiple planes, and knee strikes that demand full hip flexion. A longer inseam or absent slit would mechanically restrict each of these movements. The wide, flared short with deep side slits is the practical solution refined over decades of Thai training methodology — aesthetics followed function, not the other way around.
—
Sorting through the options and finding the best Muay Thai shorts for men ultimately comes down to how you train. The Fairtex BS1901 and Twins Special TBS offer the most authentic Thai construction and the best value for serious practitioners. The Yokkao CarbonFit is the right call if you want modern stretch fabric at a premium price. Hayabusa bridges Thai standards and Western sizing for men who want reliable fit without size guesswork. Venum Classic handles the entry-level need cleanly. Pair whichever shorts you choose with quality gloves — the guide to the best Muay Thai gloves for beginners will help you complete the kit without overspending.
