You need to buy Jiu Jitsu Gi while you undergo training under an instructor. Buying Bjj Gi should be a good investment too. You should make the investment in such a manner that it lasts long. You should invest in quality Bjj Kimonos. What makes a quality Brazilian Jiu Jitsu Gi is a million dollar question.
A quality Bjj Gi is the one that gives you flexibility to your movements when you wear it. You should feel very comfortable inside the Gi. You should never feel any sense of discomfort when you wear the Jiu Jitsu Gi. Then only you can call it a quality Bjj Gi. The Bjj Gi as you know comprises of a top and a pants. The top is the more important in the sense that it is made of fabric in such way that the opponent does not find it too difficult to grip you. Brazilian Jiu Jitsu is all about grappling and rolling. Hence the fabric used in the making of the Gi should be good enough to withstand the friction caused by rolling on the ground and the firm grips of the opponent.
The top is usually classified as single weave, double weave and gold weave. Each weave has a certain amount of thickness about it. Thus the Jiu Jitsu jacket or the top with a single weave is a delicate and a thin wear that gives ample room for the opponent to grip you. It is the kind of top normally preferred by the Jiu Jitsu exponents too during combats. The single weave Jiu Jitsu Gi is easy to wash and is considered a quality Bjj Gi. The double weave jacket is thicker than the single weave jacket in the sense that more fabric is used in its making. Its thickness would make it difficult for the opponent to grapple you with ease. The double weave jacket is also preferred by the exponents of the martial art of Brazilian Jiu Jitsu. The reason why it is preferred to the single weave jacket at times is that it is considered more durable due to its thickness. It is considered long lasting but at the same time it is not easy to wash the double weave jacket.
There is another type of jacket called the gold weave jacket. It is neither thick nor thin but is a quality Jiu Jitsu Gi. It is a special kind of Gjj Gi. It is interesting to note that all the types of Bjj Kimonos discussed above are allowed in the Brazilian Jiu Jitsu competitions by the International Brazilian Jiu Jitsu Federation. A quality Jiu Jitsu Gi should cause no harm to your skin or the body when worn. If you find the Gi tight on your body or causing scratches on the body due to roughness in the making, then you should change the Gi with a new and lighter one. A good Bjj Gi is available for an affordable price anywhere between $75 and $200. Remember all you need is a quality Bjj Gi.
