These pants are so comfortable that I may never wear denim again. There are so many pro's to this pant, comfort, sensibility, functionality and price. The only negative thing I have to say is that the color selection is too limited. Come on 5.11! This is one of the few pants that you have a solid five star rating. Add more colors!

Best pants I've ever owned.

Seriously. I'm not usually one to write reviews but these deserve it. The slim fit is perfect - not skinny jeans, not relaxed. The cut of the pant is great too, actually makes my lower half look slimmer than other slim fit pants (usually get my pants/jeans at Gap or Banana Republic).

The pockets are fantastic and well-thought out. The hidden mag pockets will fit a dip can, pack of smokes, or my iPhone 8 and are far enough away from the rear pockets to not layer against my wallet (might as well use them for something besides AR mags!). The watch pocket (little pocket inside the right front pocket) is deep- enough to fit a knife or completely conceal my NAA Pug. Front pockets are roomy.

The stretch (or "flex") in the material is great too. It holds form, so it doesn't look sloppy, but allows you to fully squat/kneel/whatever unlike regular jean material. Fit for me was pretty true to size.

I bought one pair at a 5.11 store, and now I'm about to order two more. These may be the only day-to-day pants I need.

Hopefully 5.11 comes out with some more colors/washes for the defender flex jeans, I'm not too crazy about the ones they have right now. The pants colors are great though.

Every year I save up for one or two new clothing purchases. This year it was snow pants (I'm on the local ski patrol) and these pants. They fit me perfectly (32x32), and I finally found a pair of more tactical pants that aren't parachutes on me and blend in for a more casual, college look when I'm on campus. I got volcanic, and I love the darker color. I will be saving up for some other colors and the slim pair of jeans from 5.11 . I like the pockets, and the stretch is great! Definitely worth it for a more indiscreet look.

My favorite pair of pants...

I LOVE these pants. They are hands down my favorite pair of pants I own. Really wish there was a better variety of colors. A true khaki color would be AMAZING and please for the love of all that is holy ramp up your production! I do not understand this! It is really annoying that they are ALWAYS out of stock.

Zero Complaints Here!

I purchased the stone colored pants. I can get away wearing them at the office with a polo, or button down and some smart looking shoes! Love the 2 extra hidden mag pockets on the backside! The stretch quality still feels like regular chino-type pants. I typically wear a W34 L32, but in this pants I had to go down to W32 L32 (no, I didn't lose weight). Overall a solid purchase! Looks great! Feels great! Nice features for my EDC and accessories!

Ehh not impressed

Overlooking the horrendous 3 month shipping time that I got for them being out of stock when I had purchased them, I received 2 pairs in the mail and was exited to test them out for the trip I was taking. Spent 3 weeks in Guatemala, and I don't want to say I put them through a lot of stress but already some of the stitching is coming loose, especially around the knife pocket which is really disappointing for someone who constantly carries a knife on them. The look is a solid 10/10 but in terms of form and function... Ehh not impressed

highly recommend for tall skinny people

I rarely write reviews because I'm lazy but I love these pants. I'm tall and skinny (6' 1'' and 170 lbs) and would like to think that I'm somewhat stylish. these pants fit and look great and I feel like I could still go hiking or even do squats or deadlifts while wearing them. I carry a flashlight, multitool, wallet, pen and keys on a regular basis and there is plenty of room for all these items and they all fit great in the pockets. I have (but don't carry yet) a glock 43 and it fits well inside the waist band (appendix and 4 o'clock) and a spare mag fits well in the mag pocket in the back. the pants don't look civilitary at all and I plan on wearing them out. If you want to carry your EDC but want to remain stylish and keep a low profile, these pants are for you!

5.11's Defender-Flex Slim Jeans are my favorite. I have 5 pairs of them, but .... YOU SHOULD produce them in KHAKI & COYOTE BROWN color as well.

PS. Recently i bought the Burnt color. On your site they looks very brown-red, but once I got them I love them. It's more like battle brown color, very dark brown which is ok for me.

Best regards

These pants are excellent. Top-notch quality, style, and comfort. I normally float between a 31 and 32 waste. A 31 in the Flex Defender fits me perfect and the stretchability nicely accommodates my S&W Shield and IWB holster.

One thing to be aware of: these are essentially jeans. I doubt they will pass muster as “business casual” in my work environment. But that’s okay — they look great and work well for a night on town.

The critical comment about the shallow pockets is valid. I guess I would prefer a bit more pocket, but this is not a big concern for me as the hidden mag pockets more than make up for any lost capacity.

The comment regarding the 5.11 logo on the butt, looking like the guy sat in something ... well, I don’t know what to say about that one except he may be a little too worried about how others view his rear. Sounds like a personal problem to me.

Seriously, these are some of the most comfortable pants I own. I’ve already ordered a pair of the (blue) jeans, and will likely be back for a pair of the oil green or burnt colors.

Simply awesome pants

Hands down the most comfortable pants I own. The mag pockets are great too! Perfect for my iPhone +.
I like the deep coin pocket as well. Looking forward to getting more colors, I own the Sand & Volcanic. Next purchase will be the jeans version!
Great job 511 design team!!!
