Super comfortable!!!


From Shannon


These are the new standard in my wardrobe. The attention to detail is simply the best. The fit is perfect as well. I love the hidden rear pockets too.
Great job 511 design team

Comfortable and Useful


From Thomas


The fabric on these pants is soft enough to be comfortable yet durable. I particularly like the AR mag pocket on either hip. I have thicker thighs because of weightlifting, but this pant is not too slim nor too baggy, and also has a great taper especially with boots on. Similar to the old Levi 508 fit.

Gray Tactical


From Heraldry Arms


Be prepared for the unexpected without tipping everyone off. This pant has the right silhouette for a contemporary fit with the pockets ready for extra mag, TQ, & EDC knife. Stay grey if you want to be effective- drop the obvious cargos, ripstop and paramilitary look and blend in with the Defender. I would advise going a size or two down from a TRUE waist size because of the stretch. This a pant that I can wear every day and not draw attention to myself- and that's a really effective way to keep a target off me.

Love the pants, hate the tag


From James


I love the fit of these pants; unfortunately, 511 put a brand tag on the lower right corner of the right rear pocket. Everytime I glance in a mirror it looks like I sat in something.

Even in the field I don't want people thinking I'm careless enough to sit in crap. The tag is integral to the pocket seam so I can't cut it off.

I'd buy multiple pairs but can't get past the tag placement.

The best tactical jeans ever.


From Alexandr


I was always looking for a tactical pans I can wear in a field and in evryday life for a long time And I've already had a couple of so cold "tactical jeans" from different manufacturers, befor this one came out. But all of them were good enough only at taking it outdoor rather then in big city (too many pockets, odd cut).
But defender-flex has it all. Exelent fit, casual cut and still functional enough to wear them in a range or field. I've already took one out to a camping, and ,boy, I've shown no mercy using them. But defenders took it all! And I still can get downtown without changing it or looking like a total bum.
So 5.11 did a great job desining . Defenders-flex is durable, good-looking, has an exelent fit, functional pants. Witch makes them the best tactical jeans in market so far.
Thanking you in advance.

Excellent product.


From Alberto


It is a very flexible and comfortable product I recommend it extensively.



From Alwin


I'm an Asian and I'm 5'5" and have a 32"waist and 28" inseam, so naturally any shorty would understand how hard it is for guys like us to buy tactical pants without looking like you are wearing your dad's tactical clothings. 5.11 satisfied me just right by offering this pants in 30" waist, and wait for it..... yes! 28" inseam! I don't need any alteration any this pants fit for me just right, 7 pockets around the hips mean I can stuff my everyday essentials all onto the pants and go for a ride or a walk without bringing out a bag or pack. The stretching fabrics can be a little too warm near the equator but that is the problem with all stretchable fabric. The relatively thick fabric also ensure the pants will stand straight and will not sag like ripstop pants. These goes very well with boots or leather shoes alike, depending if you are going for a short walk in the countryside or going to work in an office, it's good for all purpose. The burnt color is great, am considering getting another color, I know a jeans color version is coming up but I already have jeans that do (almost) the same so I won't need that.

Wish they offer more colors in the future.

Great low profile pants


From JB


These pants are extremely comfortable and very low profile. The waist size runs a little big which surprised me since they are slimmer pants. Usually I'm a 35-36 but the 34 fit with room to spare.
The material is a little heavy for hot weather and it would be awesome to see 5.11 expand the line with a lighter weight version.

Best tactical pant ever!


From Steve


I have two pair and want to buy the other colors whenever they get off back order. Nice slim fit without the skinny jean look. Plenty of room in the waist for comfortable IWB appendix carry. Love the hip pockets, I carry my plus size phone and still can comfortably sit down without bending or crushing. Nice durable thick fabric, quiet too. Like the oversized coin pocket which accommodates a full size folder. These pants will replace all my other bulky ugly uncomfortable cargo tactical pants. Don't change a thing! Only complaint, availability.

Best Pants I've Ever Worn


From Ollie


These pants are the best fitting pants I've ever had. The 35 is absolutely perfect and true to size. I have an athletic build and sort of wide hips and these pants are form-fitting without being tight anywhere. They ride just below my navel and stay put there when I move and bend. Feels like I'm wearing athletic pants with the range of motion I have, but they look professional enough for me to wear to work. Nice modern style. I wish the pockets were a bit deeper, but they fit all my EDC junk with no issues, and they look very "grey man"-- it's almost impossible to tell that I'm carrying "tactical" stuff in my pockets. The mag pockets are very handy for my 5.11 1.5 tactical pen and multitool and they're positioned so I can't even feel these awkwardly shaped items.
A word of advice: the extra dye (especially on the black) will rub off on something like earbuds or a white phone case. It's probably best to wash them before wearing.
TL;DR: best pants ever
