Booster Fight Gear GS Black Rashguards
The Rashguard Booster GS Black is Booster’s best-selling rashguard – timeless black, basic in design, yet excellent in terms of fit and functionality for MMA athletes and grapplers looking for a reliable rashguard without unnecessary embellishments.
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.
Polyester-elastane with stretch side panels
Made from a blend of Polyester and elastane – lightweight, quick-drying and easy to wash. The stretch side panels provide extra mobility and airflow in the areas where the most movement takes place. Double stitching at the sleeve ends and bottom provides extra durability.
The Booster Fight Gear logo is subtly incorporated into the neck trim. Timeless black design that pairs with all colors of boxing gloves and shin guards.
In addition to our online store, you can also purchase all Booster clothing in our showroom in Waddinxveen.
