Why wear a rashguard for MMA and grappling?

A rashguard protects the skin during ground fighting and takedowns – without a rashguard, the skin rubs against the mat during every contact, leading to abrasions and an increased risk of skin infections. In addition, a rashguard keeps the muscles warm and supports blood circulation, benefiting performance and recovery.

The GS Black is also excellent to wear under a gi for BJJ, or as a base layer under protective gear for kickboxing and Muay Thai.

What makes the Booster GS Rashguard suitable for MMA and grappling?

The Booster GS Rashguard is made from a polyester-elastane blend with special stretch side panels for enhanced mobility and airflow. The close-fitting design follows the body without restricting movement, which is essential during ground techniques and grappling. The lightweight material (187 g) does not hinder freedom of movement during intense MMA sessions.

What material is the Booster GS Rashguard made of?

The rashguard is made from a blend of polyester and elastane, reinforced with a specially reinforced polyester fabric. The stretch polyester fits snugly around the body and wicks away moisture, helping you stay cooler and drier during training.

How do I wash a rash guard?

Wash the rash guard at a low temperature. The polyester-elastane material is durable and retains its elasticity and shape after multiple washes. Avoid using the dryer, as high temperatures can damage the elastane fibers. Air-dry the rash guard for maximum longevity. Even after frequent washing, it remains in excellent and comfortable condition.
