The original—made for the next generation.
Our Signature Ninja Suit™ spats—now in youth sizing, built on the same platform that redefined women’s Jiu Jitsu gear.
Constructed with our NinjaTech™ performance fabric and built-in compression liner, this system delivers second-skin comfort, reliable coverage, and confidence in motion.
Adapted from our Signature Ninja Suit™ system, these youth spats deliver the same industry-defining performance, fit, and comfort—refined specifically for young athletes.
Crafted from our NinjaTech™ compression fabric, they offer a buttery-soft, second-skin feel with four-way stretch and advanced moisture-wicking performance to keep kids cool, dry, and comfortable through every class, drill, and round.
At the core is our built-in liner—providing reliable coverage, support, and confidence so kids can focus on training without distractions. No layering. No adjustments. Just performance.
The high-waisted fit features our FlowFit™ waistband—with dual elastic banding and a soft internal drawstring—creating a secure, stay-put feel that won’t roll or shift during movement while allowing for an adjustable, customized fit.
Designed with durability in mind, these spats include reinforced flatlock stitching to stand up to tough training sessions and frequent washing.
As part of the Signature Ninja Suit™ system—powered by NinjaTech™ performance fabrics, these spats pair seamlessly with our rashguards and shorts for a complete, training-ready no-gi kit.
For competition, our black Signature Ninja Suit™ spats are designed to meet International Brazilian Jiu-Jitsu Federation uniform requirements for kids—offering a clean, compliant option without sacrificing comfort, coverage, or performance.
Whether worn for no-gi training or layered under a gi, they provide lightweight comfort and performance for every session.

"The Gaidama Girls' Ninja Suit Spats are incredibly comfortable, durable, and perfect for Jiu-Jitsu training. The waistband stays in place, the fabric provides great coverage, and they hold up well through tough practices and frequent washes.

"This was so cute & my daughter needed a new one. I love the artwork!"
"These are perfect! Love the print and they are so well made. Worth the price for sure."
"My daughter absolutely loves it! It looks even better on her. I ordered the youth medium for my daughter, who is about 4’5” and 65 pounds. It fits perfectly with a little room to grow. I especially love the adjustable straps on the pants—I’ve never seen that feature on this type of pants before!"
"My Daughter Love these bottoms, they were her favorite ones out of the order!"
