The World’s Best Ninja Uniform
Tired of all the fake, low-quality ninja uniforms on the market? So were we.
Back in 2009, every “ninja uniform” we could find was a costume pretending to be gear — thin, shapeless polyester that tore the first time you moved like a ninja. So we made our own. Seventeen years and thousands of uniforms later, this is still the one we’d put our name on: a real ninja uniform, designed by martial artists, made in a limited run of 500 a year.
Real 14oz Cotton — Nearly Double the Weight
Most ninja uniforms and ninja costumes are cut from 8oz or 10oz cloth. Ours is woven from heavyweight 14oz, 100% cotton — the weight a real practitioner trains in. It drapes like it should, moves like it should, and survives years of training sessions, conventions, and Halloweens.
Built For Movement
The trousers use double waist ties plus additional ties at the knees and ankles, so nothing shifts when you do. The jacket features built-in sleeve gauntlets to cover the hands and forearms. A custom one-piece ninja mask and a real black belt complete the set — everything you need to suit up, in one box.
Limited Edition: Only 500 Made Per Year
We produce one run of 500 uniforms each year. When it sells out, there isn’t another until next year — no restocks, no reissues. That’s not a marketing gimmick; it’s how we keep quality control on a garment this labor-intensive. It’s also why sizes disappear as the year goes on.
Training gear or Halloween costume? Yes.
This is authentic training equipment for ninjutsu and martial arts — and that’s exactly what makes it the best ninja costume you’ll ever wear. While everyone else’s costume looks like a bag with a hood, a real 14oz uniform reads as the genuine article from across the room. Order by mid-October for free shipping in time for Halloween; the Priority upgrade at checkout covers the final stretch.

Found on Amazon and saw that it was much cheaper ordering direct. Fit was good and accurate. Loved that it came with a legit black belt. Not the same quality of as my $200 BJJ uniform, but that makes sense. Still, good value for the money. Well done guys 💪💪

So happy I ordered this ninja uniform! Impressed with its versatility in that it can be rolled up to fit a very short 4’11 person, and still be able to tie up ninja style while maintaining its integrity for another use with a taller human. Also just ingenious way to tighten at the waist, the arm sleeves etc., overall great uniform! Thank you for your quick response to my questions and fast delivery too.

WOW! Excellent Quality! I used to buy ninja outfits from martial arts supply stores in my hometown back in the day(early 90’s) because I never did like the garbage quality ninja outfits sold in costume shops even though they were much cheaper and the quality in this uniform surpasses even those. Excellent Ninja Uniform!!!

Very good uniform and very good quality as well! My Karate Gi is pure 100% Japanese cotton and made in Japan as well, but I have to be honest and say that Kage Ninja Gear killed it with this one. I tried my ninja uniform on the second it arrived in the mail and I LOVE IT! It looks good on me and it feels good too. Two thumbs up for Kage Ninja Gear! 👍🏼👍🏼

If you are looking for an authentic, durable gi or shozoku that allows for a wide range of motion in all appendages, then this is the item for you. Here are some things that aren’t mentioned…
There is a pocket for eggs or metsubishi on the right flap of the torso robe, so in a traditional left-over-right, it is concealed nicely under the left flap of the torso robe.
There is a shuriken pocket hidden inside the back of the neck of the torso robe, and allows for a pretty fluid throw with a right handed, overhead style. Ive practiced a few left handed reaches as well, and it seems to be feasible enough.
There are ties that hold the torso robe in place even without the belt, allowing you to tie the belt in a fashion that allows for better upper body movement, without sacrificing security of your left-over-right fold.
The pants are amazing. Far better than my judo gi with double-reinforced knees.
The ‘wrists’ of the robe do have elastic, which I really don’t like, but it does help them stay in place when tucked under the gauntlets, or rolled up to the elbow for bare handed training.
The velcro on the calves is unnecessary, but does not get in the way.
The gauntlets that come with this gi are of some very low quality. There is a tiny loop for your finger to get it to stay up on your hand. I am glad I bought the other gauntlets.
And the material is very strong (pants and torso robe). I will be quite surprised if I manage to tear this gear.

I just received my uniform today and as I am so pleased with the obvious quality and value I am placing a order for a second uniform today. It is so nice to find a source for a uniform that takes the art seriously. I do not feel like I am buying a costume, but rather a fine piece of training equipment.

They say it’s one of the best Ninja Uniforms on the market. I’d have to agree.
I’ve been using mine for the last couple of weeks and haven’t had any problems. Only issue is the tabi were a bit wide. But wearing two pairs of socks or thick black socks works well.

To Whom It May Concern:
I just had to sit down and write you a letter. After over a year of looking, and my son begging. We found your website. He has wanted a ninja outfit for a very long time. I wanted to find something that would be easy for him to get on and off, and not near as difficult as some of the others we have seen. I also wanted something that would last, and not be made of the flimsy material that I have found in countless others!
First I just have to tell you that you made a little boy VERY HAPPY TODAY! He has been checking the mail box everyday since I told him I ordered it! It came today. He was jumping up and down as he pulled it out. I wish you could of seen his face!
I am so happy with your product! It is so well made! I am thrilled that I found you! I love the fact that he can just pull the head part right over his head! I think that is what completely sold us! I haven’t found that ANYWHERE ELSE! It arrived so fast and the price was great too! I just can’t say enough good things about it! I have already told many family and friends about you! I want you to know that I will be telling everyone I know that has boys like mine about you! Including other parents in his karate class!
My only regret is that I didn’t get a picture right away to send to you!
I just had to tell you that you have blown us away and I will again be ordering from you when he outgrows this one… at his rate.. could be next week! 🙂 You should know too that he will probably be living in this until then!
Thank you Thank you Thank you! WOW!! THAT IS ALL I CAN SAY! WOW!
Sincerely,
Ingrid Riley and family

This uniform is well ok. The material is thick and not cheap costume like. But it does not have a good feel to it. Also the jacket and pants fit a little awkward. The gauntlets are kind of good. The mask is pretty good. I will keep it around as a back up.
