"Great fit. Works well for both bjj and under a singlet for wrestling."
The original. The standard.
Our Signature Ninja Suit™ rashguard—built with our NinjaTech™ performance fabric for a sculpted, second-skin fit and unmatched performance.
The foundation of the Signature Ninja Suit™ system, this women’s short sleeve Jiu Jitsu rashguard is built from the fabric that put Gaidama on the map.
Crafted from our NinjaTech™ compression fabric, it delivers a buttery-soft, second-skin feel with smoothing, body-contouring support. Engineered with four-way stretch and advanced moisture-wicking performance, it keeps you cool, dry, and comfortable through every round.
A defining feature of Gaidama women’s rashguards, the signature V-neck collar creates a more flattering, feminine fit while enhancing comfort and mobility—eliminating the restrictive feel of traditional crew neck designs.
Designed with a clean, minimalist aesthetic, this women's BJJ rashguard creates a sleek, sculpted silhouette that moves naturally with your body while minimizing friction and excess bulk.
Perforated underarm and side panels improve airflow and breathability in key heat zones, while reinforced flatlock stitching ensures durability through intense training and competition.
As part of the Signature Ninja Suit™ system—powered by NinjaTech™ performance fabrics, this rashguard pairs seamlessly with our shorts and spats for a complete, confidence-driven no-gi kit.
Designed by black belt women and tested on the mat, this is the rashguard that redefined performance in women’s Jiu Jitsu.

"Great fit. Works well for both bjj and under a singlet for wrestling."
"My gym doesn't turn on the a/c until the last possible moment so it gets pretty hot. I think the arm vents are great and I feel like they make a huge difference. I love the color and the material. I am 5'3" 117lbs and purchased a small even though I prefer the xs in spats. It is form fitting and flattering."
"Another Super comfortable rashguard! I’m glad I grabbed this color while I could because it’s so much better in person."
"Obsessed with my all pink ninja suit!"
"I love the breathability of the side panels"
"Very comfortable, true to size, easy to move in."
"Incredibly soft, incredibly comfortable. Amazing for both NoGi and under the Gi. I forget that I’m wearing it because the fit is perfect."
"Buttery soft, armpit vents, awesome color. What's not to love?"
"Super soft and comfortable. Great purchase."
"When will these be back in stock? I have been searching for a colored rash guard and the tech on these looks awesome!! Unfortunately, the ones in my size are sold out. I love rich muted colors like the Merlot and Siren."
