We all train BJJ at Progress and we know what you expect when you buy a tee from us: long lasting quality, comfort and style. We can say from experience, our tees are the real deal and the real customer reviews only back us up. If you ever have any (rare) issue with your Progress tee, 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!

We always recommend washing your Progress tee 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 tees are quick drying so it will only take a couple of hours to be ready to roll again. Never use bleach!
