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 long 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.
Clean. Confident. Built to perform.

"Super comfy and the size chart is very accurate"
"Honestly, everything I’ve bought from this brand feels like the best quality and is so comfortable. I am usually a medium and got a large in this due to it being sold out and still love the fit. Some of my favorite rash guards. I love the simplicity of it just as much as I love the fit."
"I LOVE this rashguard. Gaidama makes such good rashguards, from the super luxurious fabric to the vented underarms to the neckline. One of my favorites!"
"Literal perfection. Velvety smooth and breathable under the gi. Highly recommend <3"
"So sleek and soft. Best rashguards out there"
"Great, comfortable, high-quality. My only recommendation (other than go ahead and BUY IT) is to get a short-sleeved version for wearing under your gi. I overheat wearing the long-sleeved under my gi, but it's absolute perfection for no-gi grappling."
"Love the color! Fits just like the black Avant Garde rashguard, which is my favorite."
