You train hard. You bleed sweat. You push through rounds when others tap. At GYM NASTY, we built this brand for fighters who don’t settle. Born from a weight-loss story, refined in Thai gyms, engineered for brutal sessions, our Muay Thai gear is designed in the UK, built to last, and trusted worldwide.

With every stitch, print and fabric choice, we ask: will this survive the ring?

If yes, we release it. If not, we scrap it. Step into gear that’s made to fight.

Why GYM NASTY Exists

I lost over 88 kg, battled through my own version of “can-I make-it”, and trained at dawn when most were still sleeping.

In that grind I realised: I couldn’t find shorts, hoodies or t-shires that kept up. Fades, frays, loosening threads, they were everywhere.

So I built GYM NASTY to fill that gap. To give you gear that backs your ambition. Gear that looks bold. Feels bold. And acts bold.

GYM NASTY started as my promise to make training gear that never lets you down.

Our Muay Thai shorts bring premium satin, fast drying fabric and long lasting prints. Built to go hard every session.

What Makes Our Muay Thai Gear Different

  • Premium satin and quick-dry fabrics: built to withstand rounds, not just mirror selfies.

  • Strong stitching and long-lasting prints: because training is punishment. Your gear must survive.

  • Designed in the UK, shipped globally: one warehouse, one purpose, fighters first.

  • Real-talk fit and size inclusivity: from bigger frames to lean war-machines, everyone deserves fight-ready gear.
