Jiu-Jitsu Gear

The first decision in jiu-jitsu gear is which format your gym trains in. Gi-only academies, no-gi-only, and mixed-format gyms all start the conversation differently. If your gym is gi-based, the kimono is the first purchase. If no-gi only, you skip that entirely and start with a rash guard and shorts. Most modern academies train both formats on different days, which means the full kit eventually includes all of it, but you can phase the purchases as you confirm what your schedule actually looks like.

For gi buyers, weave type is the first spec question that actually matters. Single weave gis are lighter and cooler, which makes them genuinely better for hot climates and summer training. The trade-off is that they wear faster under heavy training frequency. Double and pearl weave gis last longer and are the more common choice for regular practitioners. Gold weave sits in the middle on weight and durability. The difference between a judo gi and a BJJ gi is not subtle: judo gis have a looser cut with wider sleeves, which creates extra grip surface. BJJ gis are cut closer to the body specifically to reduce that grip advantage. Using a judo gi in a BJJ class is technically functional but gives your training partners more to hold.

IBJJF compliance matters more once you compete. For training, most academies only care that the gi is blue, white, or black. IBJJF rules specify maximum sleeve and pant length, color restrictions, and size relative to the body. A compliant gi for competition typically costs a bit more and fits more precisely. If you are training casually with no tournament plans, compliance is irrelevant. If you plan to compete within the first year, it is worth buying compliant from the start rather than replacing later.

Rash guards function differently depending on format. In gi training, they go under the kimono to reduce mat burn and manage moisture. In no-gi training, they are outerwear and often carry more visual significance since they are visible throughout class. Long sleeve rash guards offer more coverage and are the competition standard in most no-gi rulesets. Short sleeve works for training. Compression spats worn under grappling shorts or alone are part of the same no-gi ecosystem and often purchased alongside a rash guard.

Grappling shorts for jiu-jitsu need to survive mat work, which means the fabric and waistband design matter more than they would in striking arts. Hook-and-loop or drawstring closures without exposed metal are the standard because metal hardware catches on fabric during scrambles and creates injury risk. Board shorts are not suitable for regular BJJ training. Inseam length is personal, but longer inseams reduce skin-on-mat contact during guard work and are preferred by most practitioners once they have trained enough to notice the difference.

Ear guards prevent cauliflower ear, which is the permanent deformation of the outer ear cartilage caused by repeated compression during takedowns and clinch work. It is not a risk that announces itself early. Many practitioners train for months before the first signs appear. At that point, the deformation can be partially reversed with early drainage, but once the cartilage hardens the change is permanent. Ear guards are the only preventive tool. The argument against them is that they limit hearing and can be awkward in clinch positions. The argument for them is that cauliflower ear is not reversible once it sets.

Finger tape is the piece of gear that the largest number of practitioners buy too late. Grip-intensive training loads the finger joints repeatedly across every round, and the tendons and ligaments around the proximal interphalangeal joint are among the most commonly strained structures in jiu-jitsu. Taping after the first strain is the typical pattern, but preventive taping for practitioners who train more than three times per week is worth considering before the injury happens. The H-taping method for finger support is the most widely used among experienced grapplers.

Jiu-jitsu gear is not the right category for someone who has not yet found a gym and committed to a first class. The sport requires an in-person environment to learn safely, and the specific gear you need depends heavily on the format your academy trains in. If you have already joined a gym and know your format, the kit makes sense to build out systematically. If you are still deciding, wait until after the first week before buying anything beyond a rash guard and shorts.
