Study: Pockets of women's pants are 50% smaller than of men's pants. The proof is in The Pudding.

In other words, women’s pockets are 48 percent shorter and three percent narrower—nearly half the size of men's pockets.
Straight jeans are even worse: Women’s front pockets are 46 percent shorter and 10 percent narrower than their counterparts in men’s pants, measuring 3.4 inches shorter and .6 inches narrower.

Point taken. 
YES!!!! 
Strip of material stitched across the spot where a pocket SHOULD BE with a button sewn on.
the only place that women should "dress" is for a party or other social event and will be assumed to carry a "bag".
When I went to see an EWF concert last year, I found myself in a major quandary because I didn't want to carry a standard pocketbook (not to a concert, oh HELL no!) and the pocket issue reared its ugly head (this was in late summer so wearing a jacket with pockets was out). Ended up getting one of those wrist wallets which was small enough not to be too intrusive but large enough to hold my iPhone 6+ (with a case) + tickets + credit cards/cash and a few other items like tissues, etc). I ended up getting one of these at LL Bean -
It was still a bit cumbersome when holding it and trying to take pics at the concert but not excessively so and at least it had a strong wrist strap and I felt pretty secure carrying it. Plus it has well-made zippers and is made with sturdy material. It is now what I use for everyday when I am out and about without a need for a whole pocketbook. I can keep my car key (which is a long keyfob thing due to the car being keyless entry) in my pocket (MUST always have clothes with a pocket when out).
If I had had deep enough pockets, I could have had a slim wallet with what was needed + keys for one pocket and the phone in the other.
BUT you can fill up your pants, shirt and jacket pockets! Not realizing this, I recently had to go back to the car and ditch my tiny cross body bag. My jean pockets did not securely hold my ID, cards, money, phone and keys.
NOT ONE MAN WAS CARRYING A CLEAR BACKPACK OR BAG! 
(where the '76ers and Flyers play too) and we had to go through security (magnetometer and bag check). Having that wrist wallet made the process pretty simple in terms of only having the small wrist wallet for them to open and look at. Of course going through that metal detector meant pockets had to be emptied and it was amazing what men were carrying around in theirs - filling up whole bins and whatnot.
so... they probably figured the bag searches were good enough when it comes to us geezers. 
And yeah - as a parent, you better have some kind of huge bag to carry -
1.) toys that MUST be brought or melt-down
2.) crayons/paper
3.) extra wipes
4.) juice boxes
5.) "cool" rocks, "cool" leaves, "cool" twigs, "cool" shells
6.) bandaids
7.) extra pair of socks
OR to be a host on Fox News!!! Ain't no pockets in those outfits!!! 
Nice little wallet if you don't have the necessary pockets.
Some of the coolest pants and tops that I've seen on women was in the hospital - scrubs! Some of them have all kinds of pockets, enough for pretty much everything.
This was the first thing that came to mind!
Yes I have seen many folks wearing scrubs as regular casual wear, with the tops even layered with a turtleneck like a jumper. All different colors too. Nice and airy and lots of pockets!
Thanks for starting my day with a chuckle!
I’m having my morning coffee ☕️ and reading DU on my day off, having just donned my Academy Sports capri length sports leggings with not one, but TWO pockets!
where the "rooster" thinks it rules the roost and knows what's best for the hens. 
who want to "show off" their figures with form-fitting clothing (whether dresses, skirts, or pants), that's fine. And they realize that they have to find a way to carry their now-larger phones, where with the casual "skinny jeans" and short pockets, you can't do it. What I have seen used in that situation as an alternative, is the small backpack (or "daypack" ), some of which are made to look like pocketbooks and can get fancy (I actually use one myself) -
But for everyone else and particularly with tightened security at venues, it puts women at a big disadvantage not to have enough or deep enough pockets to be able to finally ditch the bag. Far too many of us have been there, done that, wore the t-shirt regarding "fanny packs" and cross-strap pocketbooks or other similar things that can still be ripped off the body like a regular pocketbook.
And yeah -for women's' sports like tennis, the traditional dress and bloomers (old-fashioned term for them ) just doesn't allow for carrying anything. I used to play varsity badminton in high school and it was the same issue and similar outfit - no place to put the extra shuttlecocks except in their tube along the side of the court. Trying to stuff a couple pieces of cork and feathers in the bra was a no-go!
That men's pockets are often made of tougher fabric for decades. Maybe it's because as a daughter, wife, lover, friend, etc I've done so much laundry and taylor/seamstress work over the years? 
Although I actually 'like' to carry a purse most of the time, pockets can be handy. It's annoying as heck when they're uber short though so I've replaced and extended pockets a few times over the years.
the other day... I was visiting in Minneapolis and riding an elevator with a group of women Renaissance reenactors... conversation turned to clothing (I am a seamstress) and one of the women said I should start a business just putting pockets in women's clothing who would have guessed???
Occurred to me to do just that as a business either.
One of my pet peeves has been not only smaller pockets, but actually even finding pants WITH pockets. And don't get me started with finding womens' sweat/lounge pants with pockets. 
Nowadays, with the proliferation of cell phones, which are obviously not limited to men having them, it behooves women who like to carry them constantly (usually the youngin's ) to have a place to slide them when not in use as easily as men do.
I remember way back pre-"smart phone" when the "candy bar" phone was a "thing" but where one of the bragging points about one of the flip/clamshell phones - the Motorola Razr - was it being so slim that it could fit in pocket of the skinny jeans being pushed at the time.
guess that's the reason we're still married.
Certainly you saw posters in this thread (me included) give anecdotal examples of items that have been found to fit the criteria desired, whether designed by men or women. However did you read the article I posted here - https://www.democraticunderground.com/10181119139#post31
The bottom line was this -
So how can an industry that focuses on women—whether it be models or products created primarily for a female demographic—consistently dodge the very people it markets to? Camilla Olson, creative director of an eponymous high tech fashion firm, points to inherent sexism within the industry. Mid-range fashion is a male dominated business, driven not by form and function, but by design and how fabric best drapes the body.
“I honestly believe the fashion industry is not helping women advance,” Olson said. And the lack of functional designs for women is one example. "We [women] know clearly we need pockets to carry technology and I think it’s expected we are going to carry a purse. When we’re working we don’t carry purses around. A pocket is a reasonable thing.”
https://www.theatlantic.com/technology/archive/2014/09/the-gender-politics-of-pockets/380935/
I.e., the industry itself is male-dominated. And when it comes to regular women's clothing, NOT high-falutin' runway model Melania-wearing stuff - just regular every day wear, you have to hunt for items with sufficient numbers and types of pockets. For men, they just go in the store, find the size and color and fit and out they go. Pockets are assumed and it doesn't raise a 2nd thought because it is an expected part of the clothing.
At this point, continually making women's slacks and skirts without pockets is like making men's briefs without the crotch flap. It changes the whole dynamic of how you go about your business.
.... and I have never used the crotch flap in my life.
The bottom line is men have a much easier time with clothing. I really do not understand why a pair of pants for a woman can't have a pocket at least large enough for a cell phone. Seems a simple process to me to incorporate that type of pocket without taking anything away from the fashion.
Speaking for myself, being male, I personally cannot stand to have crap bulging out of my pockets. I'll even hang my car keys on my back pocket or just carry them rather than having them bulging out of my front pockets although there is plenty of room for them. Think I'll probably bail out of this thread now, and I wish you good luck with the pants.
Many clothing line including Target, and Walmart feature clothing designed bi women. My humble suggestion to you and everyone else asking, I would contact some of these women designers and ask them, then return to DU and let everyone know what their reasoning is, although the answer is included in the link I provided through the questions asked at said link. Other than that?
I have newer pants that look like they have pockets, but they're so short that they're useless!
