Heavyweight Jiu Jitsu Rash Guard LIMITED EDITION
Great fit and feel!

Couldn't ask for more from a rash guard, being bigger im always weary of how things will fit. But the length was exactly what I wanted. The rubber banding at the bottom worked perfectly. It feels very sturdy, and the colors pop so well! The print and design are so nice! It also dried quickly after doing 10x3 minute rolls!

Retro Grappler Custom Sides Short Sleeve Rash Guard. (x 1)

I like the material of the rashguard and i love the silicon strip on the bottom to keep the rashguard from sliding up.

Tiger Pressure BJJ Rash Guard
Books are fabulous 👌🏻

I first bought the ABC's of Jiu-Jitsu for my gym. Then I bought another for a gift. When my grandsons where visiting they loved the book at our gym so I bought them both books since there is three of them so close in age. I love these fun ABC books 📚 ✌🏻

Great quality

The rash guard is very durable and the adult small fit my 13 year old daughter well. She is on the taller side and youth xl is usually short for her. Will definitely buy from here again
