Gear & Buying Guides

The right gear won't earn you a belt, but the wrong gear gets in your way — a gi that shrinks two sizes, a rash guard that pills in a month. These buying guides help you choose Brazilian jiu-jitsu (BJJ) gear that performs and lasts, from your very first gi to a full competition kit, so you buy well instead of buying twice.

Start with the fundamentals of fit: how to size a gi correctly, what to wear under it, and for parents, kids' gi sizing. For no-gi, we cover the best BJJ rash guards, whether you need spats, and what to wear to no-gi. Deciding on a gi itself? Read our Kingz gi comparison and the guides to must-have gear-bag items and choosing the right bag.

Gear is where jiu-jitsu content meets a real buying decision, and we'd rather help you get it right. When you're ready, explore the full range of Kingz gis, rash guards, and belts — worn by world champions and built for daily training.
