DIY kevlar jeans with pictures

Hi all,

I recently had an accident and it got me thinking that I should really improve my short ride gear, which I am often very lazy with. I know I won't suit up for a 3 minute city drive so one of my solutions was kevlar jeans, amongst other things. Unfortunately, the products that are out there are WAY overpriced, pretty ugly, don't provide a slim fit, and many only provide small patches of protection. So, I made my own which I would highly recommend if this type of product interests you.

I bought a pair of my favorite jeans, Levi's 514 slim fit - $30
2 yards x 56" of k129 Aramid/kevlar - $25
Kevlar thread - $4
Total cost of materials - $59

I then took it to my local tailor, who did the job for $50. So my total cost was $109 and here is the result:

514 jeans that look no different on the outside than a normal pair
Kevlar lining throughout the entirety of the jeans, not just impact areas
Double thickness in the knees and butt (although he misunderstand the instructions and the double patch on the butt could be placed a bit better)

He also constructed a pair of "pants" from the kevlar and then sewed the entire piece into the jeans. Looking at it, it seems this would offer a good safety in the event of seams blowing apart - the entire lining would have to come loose.

All-in-all, a great little project that took no effort on my part. A great deal for $109 and if you can sew, this would be super cheap. Hope this helps some of you since I couldn't really find a writeup/pictures from anyone on the web.

not bad. the flexability on those must be pure hell.

most kevlar jeans dont have that much on it to begin with and they suck at mobility.


but those only helps with abrasion; and idk how much, although a lot better than just cotton jeans. most of the kevlar jeans usually use heavier/thicker denim vs the normal jeans you buy.

Yep, top points for creativity and frugality, but I can't wear Kevlar jeans anymore.

After a few years of racing in one-piece leathers, getting around on the street in Kevlar jeans leaves me feeling naked and vulnerable.

Just invested in a pair of armoured Cordura pants. Much better.

But what you have there is definitely better than a pair of standard Levis if ATGATT isn't your thing.

Thanks for the comments guys.

These are a good fit for me since I know a leather suit won't protect me from my closet and on short jaunts I just won't actually gear up, no matter what I buy. I'm sure there are others out there who are the same.

As for the mobility, it actually isn't affected at all. I do however, notice a heavier/hotter feel but I guess that is to be expected - nothing too extreme though.

Just another thought... Physically, I see no reason why someone couldn't do this same process with 2, 3, 4, or 5 layers. Could be another option as a compromise for people who want the street look but aren't willing settle for the protection of only 1 full layer with a little extra in the impact areas. I may do this with another pair as an experiment to see how it works.

As for the women's cut, they have a completely different build so it wouldn't work unfortunately.

So if you would not pull leathers out for a short trip why would you put on different pants that are going to be heavier/hotter?

Personally I throw on a pair of over pants that are ventilated and have padding/armor built in. I even wear shorts underneath and can take them off to walk around at my destination.

One last note, this material will fray at the edges since kevlar is the tightest weave around and is tough to cut.

I found a few spots that looked like they would cause an issue later down the road and had to touch them up with my ghetto looking, but strong, army sewing skills.

My recommendation to anyone who is doing this is to leave extra material on the edges when sewing a seam. It will make slightly uglier seams but will avoid any potential issues

After living with these for a bit, I am really impressed at how much they behave like normal fabric in there. I am also feeling confident that this isn't a tough project to take on at home. I'm going to make my own pair or line this with another layer + thin cotton inner layer. I'll post updates to see if this is something that a person with very limited sewing skills can take on.

Well, I'm definitely going to do this. I didn't realize the A/K fabric was so cheap. One question, what grade of fabric do you suggest? I say you used k129, was that for any specific reason? What weight fabric gives the most compromise between flexibility/comfort and protection? I definitely like the idea of sewing in knee pads/ or pockets for them.

How do they wash? normal jeans stretch and shrink a bit when worn/washed, I'm assuming the A/K fabric doesn't. Does that affect how the jeans look and function? Does the fabric have any special washing needs to prevent degradation of the fibers?
