It is not mandatory to wear a rashguard under the GI when training in our Dojo, however it is strongly recommended for different reasons.
Even if we clean and disinfect our mats regularly, wearing a rashguard can additionally protect your skin from potential skin diseases and infections. It acts as a barrier against bacteria.
Moreover, rashguards can help maintain personal hygiene by absorbing sweat and reducing friction that cause bruises on the skin. In addition , wearing a rashguard can also contribute to the longevity of your gi by reducing the amount of sweat that it absorbs.
Remember, it’s not just about comfort, but also about health and hygiene. So, wearing a rashguard under your gi can be a good practice.
