Check out our full size chart above ⬆️ Our rashguards fit a little tight, so if you prefer a looser fit, feel free to size up!
We all train BJJ at Progress and we know what you expect when you buy rashguards from us: long lasting quality, comfort and style. We can say from experience, our rashguards are the real deal and the real customer reviews only back us up. If you ever have any (rare) issue with your Progress rashguards, please get in touch with us by e-mail support@progressjj.co.uk or on social media @progressjj and we'll do our best to fix any issues you have. That's a promise!
Although all our rashguards now have anti-bobble technology, we always recommend washing your Progress rashguards on a cold wash. If you have to wash hot, please do not exceed 30 degree. Do not use a tumble dryer, only hang dry, all our rashguards are quick drying so it will only take a couple of hours to be ready to roll again. Never use bleach!
The Progress Guarantee

Shop with total confidence, we have a 90-day hassle free returns policy and because we know our products are the best in the world, we guarantee to replace any damaged products for the first 6 months!

Koi rashguard

Fits well and has a really comfy fit during rolls. Very figure hugging so I feel ripped in it which is a bonus
