Polyester Silk Blue Shorts – Red Trim, White Stars, Thai Lettering

Description

These are classic Muay Thai-style shorts done right — blue polyester silk with wide red side panels, white stars, and traditional Thai lettering. If you train Muay Thai, kickboxing, or MMA, you’ve seen this design on fighters for decades. There’s a reason it’s stuck around: it looks great, moves well, and costs less than a night out.

Why the fabric matters

Polyester silk is the standard material for traditional Muay Thai shorts, and it earns that status. It’s lightweight, so it won’t drag or bunch when you’re throwing kicks or working the clinch. It dries quickly after a training session, and it holds its colour wash after wash without fading or going stiff.

This isn’t the same as woven satin or heavy canvas shorts. The material has a slight sheen and a soft drape — the look and feel you associate with classic Thai boxing shorts. If you’ve trained in cotton gym shorts before, you’ll notice the difference immediately. Less resistance, more freedom.

Design and construction

The shorts are blue with wide red trim panels running down each side. White stars are printed on those red panels, and traditional Thai lettering runs across the front. It’s a clean, traditional design — nothing flashy, nothing that dates itself quickly.

The waistband is 10cm wide with elastic and a drawstring. That combination matters: elastic alone can roll or dig in, but the drawstring lets you fine-tune the fit so the waistband sits flat and stays put through rounds of pad work or sparring. The wider waistband also distributes pressure better than a narrow one, which you notice after an hour of training.

What these shorts are good for

These work well for Muay Thai, kickboxing, MMA, and general striking training. The cut is designed for kicking — there’s enough room through the thigh and the leg openings are wide enough that high kicks don’t feel restricted.

They’re also fine for gym training, crossfit, running, or any activity where you want lightweight shorts that move with you. The design is recognisably Thai boxing, so if you want shorts that look like gym shorts rather than fight gear, these probably aren’t what you’re after.

What these shorts are NOT good for

If you compete and your organisation has specific uniform requirements, check those before buying. Some competitions require plain colours or have restrictions on logos and lettering. These shorts are primarily training gear.

They’re also not grappling shorts — if you spend a lot of time on the ground doing BJJ or wrestling, you’d be better served by board shorts or hybrid MMA shorts that handle mat friction differently.

Sizing guidance

These are available in M and L. Thai shorts typically size smaller than standard Australian clothing — if you’re between sizes, go up. The drawstring gives you some adjustment room at the waist, but the overall fit through the hip and thigh is determined by the size you choose.

Check the size chart (shown in the product images) before ordering. It lists waist measurements in centimetres for each size.

Care instructions

Machine wash cold, gentle cycle. Turn inside out if you want to preserve the print longer. Air dry — the dryer will eventually degrade the elastic in the waistband and loosen the print. These don’t need ironing; the fabric sits fine without it.

Frequently Asked Questions

What does “polyester silk” mean — is this actual silk?

No, it’s not natural silk. “Polyester silk” refers to a lightweight, smooth polyester fabric that mimics the drape and sheen of silk. It’s the standard fabric for traditional Thai boxing shorts — lighter and more breathable than heavier synthetic fabrics, and it dries quickly after training.

Are these the right size for me? Thai shorts seem to run small.

Yes, Thai shorts generally size smaller than standard Australian clothing. Check the size chart in the product images — it lists waist measurements in centimetres. If you’re between sizes, go up. The drawstring allows some adjustment, but the cut through the hip and thigh is fixed by size.

Can I use these for BJJ or grappling?

These are designed for striking sports, not grappling. The lightweight fabric handles mat friction differently to board shorts or hybrid MMA shorts, which are purpose-built for ground work. For BJJ or wrestling, you’d be better off with something more durable for that purpose.

Do the shorts come with a drawstring, or is it just elastic?

Both. The 10cm waistband has elastic built in, plus a drawstring so you can fine-tune the fit. The combination keeps the waistband sitting flat without rolling or digging in during training.

What’s the shipping situation in Australia?

Pacific Sports ships Australia-wide. Orders over AUD $150 qualify for free shipping. For orders under that amount, standard shipping rates apply — check the delivery policy page for current rates and estimated timeframes.

Are these suitable for competition or just training?

These are primarily training shorts. If you compete, check your organisation’s uniform requirements — some competitions restrict logos, lettering, or colour combinations. For regular training and sparring, there are no restrictions and these are a solid choice.
