Greyman Jeans

 Rated 5.0 stars



This is the almost perfect pair of active jeans with only one flaw being (for lack of a better term) no kick-plate at bottom rear of jeans.
Stretch is perfect for mobility and movement and Dark Wash Indigo is a perfect tone w/ whiskering.
Maybe a double-layer at front pockets for knife-carry then this would be a perfect Greyman Tac-Jeans.

slim partially

About size - I'm 193 pounds / 87.5 kilos, 5,9 ft/ 180cm, physical waist size is 35 inches / 89 cm but jeans size is 32/32 and it fitted perfect for me. I'm absolutely sure necessery to try it on before buying.
After reviews reading I'm was awaiting not a slim pants but "almost slim". Jeans a little more slimmest then straight jeans and tightly cover a calf only.
Good raw material quality, very good executing, two additional pockets it is a absolutely perfect idea and two bealt loop on a back instead one too. I like these jeans but I think slim model more for summer, for winter I would like to buy stright defender model.

Probably the only jeans I'll ever wear from now on.

I have been wearing the same pair of the slim fit, indigo wash for the last 3 months. One of the first things I tried in these was pistols (one leg squat) something I have never even thought to try in other jeans. I carry appendix in these with no problem. Crawl around on the floor playing with the kids, and hiking around the woods along with everything else that comes with daily life in the mountains. My wife often asks me in the evening when I'm going to put on my sweatpants and as ridiculous as it sounds I honestly prefer these jeans over sweats. While most reviews here note negatively that the jeans shed indigo I personally love this. I'm coming from a pair of raw denim that is also designed to do that so that it wears into the use you put it through. These are definitely starting to show character and I love that. I'm probably going to by another pair just in case they ever stop dyeing them this way.

Great pants, not a slim fit

 Rated 3.0 stars

From Andrew


These pants are great quality but they are by no means a slim fit. The pair I have are more of a loose fit through the thigh and seat area with a lot of extra material compared to other slim fit jeans I wear. I also have the strait fit version of these and the only difference I can see between the two is the leg opening on these is a little narrower than the strait fit. The materials and features of this jean are great, I just wish it was a true slim fit and wasn't so baggy.

Nailed it!

I've been around the brand long enough to have had several pair of the old Tactical Jeans. Which. Were. Terrible.

These are light, super flexible, well patterned, comfortable and best of all subtle. Not sure where the complaints come from about the pocket depth. They're about the same depth as every other brand of jeans I've worn. It's also nice to have a 'coin' pocket that will fit... something. Long gone are the days where a nickel will buy you a steak and kidney pie, a cup of coffee, a slice of cheesecake and a newsreel... with enough change left over to ride the trolley from Battery Park to the polo grounds.

I'm stuck with the Dark Wash model because the Indigo has tone on tone stitching which looks odd. Levis has clearly indoctrinated me to think not having yellow stitching is weird.

Yes, the dye runs. Read the washing instructions. Wash with vinegar before wearing them to set the colour. It is annoying, but it has the warning tag on there...

(Basically) Perfect

Everything about these jeans are perfect... as long as you get the right size. I normally wear a 34/34, but I got a 32/32 and they fit exactly like my other slim jeans. Awesome pockets and conceivability, durable, and EXTREMELY comfortable.

I finally found my Jeans!!

I have tried on every jean out there, baggy or slim and they never looked or felt good. But these 5.11 Defender Flex Slim Jeans are freakin amazing! I just bought 2 more and plan to buy more. They are slim in all the right places and the fabric is awesome. I use them for work and wear them out in my personal life. Please do not change anything about these Jeans. They are PERFECT!

Bought these as an all-purpose jean for weekend adventure, training without needing to be kitted out and general wear.

First, the quality is great. They feel durable but they still move well. Getting a 36” inseam is also awesome as a taller guy with a lean build (6’4” 185 lbs) and limited options.

But the slim part is where they miss, as do many other clothing companies who do “slim.”

They are super loose in the seat/upper legs and even after a wash dont have a great fit. That’s fine forna regulat pant but disappointing for something sold as a slim pant. I even double checked the tags to make sure I didn’t get the straight fit by mistake.

Hoping they refine these a bit to make a jean closer to the VertX Delta pant.

The Perfect Jean

 Rated 5.0 stars

From Scott


I bought a pair of the slim fit because the straight fit wasn't available yet. I am NOT a slim fit kind of guy, but these pants are not your kid's slim fit. They are comfortable and look good with most kinds of shoes/sandals. or boots I would get the straight fit - I like the mag pockets because my cell phone fits perfect and when you're sitting down the phone sits higher so no "butt dials", and you are comfortable. Gonna buy some other colors next

My new favorite Jean!

 Rated 5.0 stars

From Anthony


Have both colors in Slim fit and they are amazing. Just the right amount of slim without being too tight but nicer than a relaxed fit Levi. Pockets placement and quality is superb. I'm 6'4" 220lbs. and the 35w 36L fit like a glove. Only wish you offered them in some FDE or tan and Grey colors. Heres to hoping the color offerings expand. Otherwise don't change a thing!
