FAQs

Are these shorts suitable for competition?
Yes! The bold colour combination and authentic Thai construction make them perfect for both training and competition use.

How should I wash these shorts?
Hand wash in cold water or machine wash on a gentle cycle. Hang dry to preserve the vibrant yellow, red, and white colours—do not tumble dry.

Can I wear these for kickboxing or MMA?
Absolutely! The classic Thai cut and side slits make them ideal for any striking-based martial art including kickboxing and MMA striking sessions.

Will the colours fade after washing?
With proper care (cold wash, air dry), the vibrant yellow, red, and white will stay bold through years of training.
