Rash guards are tight-fitting, long-sleeved tops worn during grappling and MMA. They are made of stretchy, breathable material and offer protection from friction and abrasions.
One of the biggest benefits of rash guards is the protection they provide. When you rub on a mat during martial arts, it can cause skin irritation and abrasions. Rash guards provide a barrier between your skin and the mat to minimize friction and prevent injuries. They are also helpful in protecting against scratches or cuts that can be caused by sharp nails or jewelry.
Another benefit of rash guards is breathability. The material wicks sweat and moisture away from your body to keep you dry and comfortable. This is especially important since you will be sweating a lot during sports. If you're in a wet, sweaty t-shirt, it can restrict your movements and affect your performance.
Rash guards also provide a better grip. The stretchy material ensures that your opponent can't get an easy grip on your body, making it harder to control you. There are also some rash guards with special grip zones that provide extra grip.
