Compression fit, one solid colour, nothing extra. This is the baseline piece of no-gi kit, the one you pull on without thinking before you step on the mats.<\/p>\n<h2>What a rashguard does in no-gi<\/h2>\n<p>Without a gi, your skin rubs straight against your training partner and against the mat. The rashguard sits in between. It cuts down mat burn and reduces the micro-abrasions that let most grappling skin infections in: impetigo, herpes gladiatorum, ringworm. It also soaks up sweat instead of letting it run onto contact surfaces.<\/p>\n<p>The second job is mechanical. A compression knit holds the muscles in place, limits vibration through changes of pace and pushes back the point where fatigue sets in during long rolling sessions.<\/p>\n<h3>Long sleeve or short sleeve<\/h3>\n<p>Long sleeves cover the forearms, the area that takes the most work in closed guard, wrist control and guard passing. They also keep you off the wrong end of a badly trimmed fingernail, a gym classic. The trade-off is heat. If your gym has poor ventilation in July, keep a short sleeve in rotation.<\/p>\n<h2>Black long sleeve rashguard and IBJJF rules<\/h2>\n<p>Worth knowing before you order. For no-gi, the IBJJF requires a rashguard in black, white, or black and white, carrying at least 10 % of the athlete&#8217;s rank colour. The rulebook also accepts a garment that is entirely the rank colour.<\/p>\n<p>This model is fully black. It therefore meets IBJJF rules for black belt competitors, and for them only. If you are a blue, purple or brown belt, you will need a rashguard showing at least 10 % of your belt colour to clear the uniform check.<\/p>\n<p>Outside IBJJF competition the question does not arise. For training, open mats, local events and most amateur circuits, this rashguard works at any rank.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Black long sleeve rashguard built for no-gi Brazilian jiu-jitsu, grappling and MMA.
