Designed in the UK, our premium Muay Thai shorts made for hard rounds, not just the mirror.
I built GYM NASTY after my own weight loss journey and trips to Thailand, fixing the things that used to let me down.
Strong stitching, quick dry fabric, colours that last. Get Fight Ready!
I built GYM NASTY after losing over 196lbs (88KG) stone and finding most Muay Thai gear failed under pressure.
Going from 4XL to S was no easy feat, but it taught me a lot.

Throughout my weight loss journey, I started designing my own Muay Thai gear.
Gear that was different, that made me feel and look good.
Working with manufacturers, I designed and developed my own Muay Thai gear.
The best Muay Thai shorts that would last the toughest of battles.
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.
