Jiu-Jitsu Shorts

For No-Gi training, Jiu-Jitsu shorts are an essential piece of attire. They’re designed specifically for grappling, ensuring comfort and freedom of movement. 

Some practitioners even wear them under their Gi. Look for shorts with an elastic waistband and durable material to withstand intense rolling sessions.

Like spats, leggings provide compression and support while training in your Gi. They’re usually made from stretchy, moisture-wicking materials like polyester or spandex. 

Leggings offer an added layer of comfort and protection during your Jiu-Jitsu sessions.

In summary, prioritize comfort when choosing undergarments for your BJJ Gi. 

A powerful combination of rash guards, spats or leggings, and Jiu-Jitsu shorts will help you excel on the mat, ensuring comfort, protection, and peak performance.

Additional BJJ Clothing Items

T-Shirt Recommendations

When training in BJJ, it’s essential to wear a breathable and comfortable t-shirt or rash guard under your gi jacket. 

A rash guard is preferred because it doesn’t soak up sweat like t-shirts. Choose between a short sleeve or a long sleeve based on personal preference.

Socks and Footwear

For proper personal hygiene during BJJ training, wear socks and flip-flops when walking around outside the mat area. 

On the mat, train barefoot to maintain proper grip and stability. Remember to keep your feet clean to avoid infections.

Training Belts

When it comes to belts, always wear the appropriate BJJ belt to represent your rank in the martial art. 

A white belt is commonly used for beginners in BJJ practice, but belts vary depending on experience.

Compression Shorts

Underneath your BJJ gi pants, opt for compression shorts or jiu-jitsu underwear designed specifically for the demands of BJJ training. 

These items provide the right balance of comfort and functionality, ensuring smooth movement and protection during practice. Additionally, females may wear a sports bra under their gi top for support.

Hygiene and Safety Considerations
