Rash guards
For no-gi competition under AJP or IBJJF, a rash guard must be black, white, or black and white — and must carry at least 10% of your belt rank colour. A rash guard that is 100% your rank colour is also permitted. Most rash guards sold in this country meet neither rule, because nobody selling them mentions it.
The no-gi colour rule, in full
AJP requires a shirt of elastic material, skin tight, long enough to cover the torso to the waistband. Permitted colours are black, white, or black and white, with at least 10% of the athlete's rank colour present. A shirt that is entirely the rank colour is also allowed. Black belts get a small tolerance for red. Training rash guards have no such restriction — this only bites on competition day.
Long sleeve or short sleeve
Both are legal. Long sleeve protects the forearms in guard passing and keeps mat burn off the elbows, which matters more than most people expect on the harder mats common in UAE academies. Short sleeve runs cooler. In a Gulf summer that is not a small difference — but neither is the friction, so most people end up owning one of each.
Why they fail here
Rash guards rot before they wear out in this climate. The failure is not the fabric, it is the elastic and the seam tape, both of which give up when a garment spends its life damp. Rinse after training, never leave one in a closed bag, and expect a rotation of two to last longer than a single expensive one.
