New favorite pants

 Rated 5.0 stars

From TeeCee


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!!!

great pants but need some tweaks

big fan of the defender pants! my only complaints are the small pocket sizes and the confusing name for the cuts.

come one guys the "5th pocket is as big and deep as the back pocket.... smaller pockets then my levis

the slim is not a slim at all just a tapered leg and the regular are really just a boot cut. almost didnt buy a pair because i thought the slims were slim fit.

add some more colors to the jeans with bigger pockets and you'll have a real 5 star product!

Super comfortable!!!

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

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.

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

 Rated 3.0 stars

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.

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.
