Don't wear with out pants underneath!

Both these for my wife - she ordered the largest size as recommended from the sizing chart and were still a little small for her. She choose to try them without pants underneath which is not a great idea as they stick to you legs! Other then fit they perform well, are water proof and the reflective detail is great looking and functional.

Lacking comfort, durability.

Purchased this pant in a large, regular length. I normally wear size 34x32 pants.
These pants represented several flaws while riding; firstly, they are not curved in the riding position. As such, sitting on the bike will cause them to ride up on your boots (which, hopefully, you have full, 12'' boots on). The hard CE armor in the knees is sturdy and will protect you in a fall... IF they're in the right place which, because of the non-curved nature, can't be answered for certain. Not only that, but the same CE armor can tend to ride up onto your knees which, because of the slim fit, can lead to a very uncomfortable ride, constantly re-adjusting the knee pads so they don't mash against your kneecap.
The pants lack a full-length side zipper, however the to-the-knee zippers present should be sufficient to aid in the easy removal of these if used as overpants. You'd be advised against attempting to take them on and off over boots since, as stated before, they fit slim and thus don't provide much room for the boot to maneuver. Not only that, but you may risk the sole of the boot tearing through the waterproof liner.
Which, unfortunately, brings me to my last negative issue with the pants; materials. The abrasion resistance of the pants is tolerable (I had an unfortunate get-off at low speeds; the pants shredded away, but my jeans underneath were unscathed), but the heat resistance leaves something to be desired. While getting back onto my bike after stopping, the pants touched the exhaust pipe running out from under the engine (near where your leg might normally touch during an average ride). The heat from the exhaust almost immediately burned through not only the outer layer of the pants, but also the inner water-proof layer as well leaving enough space to poke my fingers through.
Not all of this pant is bad; the reflective stripes are quite visible, the armor, if in the correct position, is sturdy, and they are quite comfortable for walking around. The price is quite commendable for a set of waterproof pants and, of course, the customer service from the Revzilla and Rev'It guys is quite good.
Is it possible I bought a "bad" pair of these pants? Possibly. Rev'It wouldn't accept the pants back under warranty due to the exhaust heat issue, which is unfortunate because I really wanted to like these pants (and try them in a Large-Long to see if the fit was improved).
Given the issues noted, these pants have a bit of a ways to go before they match their price tag. Until then, Fieldsheer makes a great set of overpants with full side zippers that can keep you occupied until Rev'It catches up in the overpant department.

Great variety of sizes! Excellent for the plus-size woman rider

I had been on a fruitless search for a pair of pants that fit my particular plus-size frame. (bigger hips, smaller waist, 5'4'' height). I was happy to find that the RevIT Zip pants offered plus sizes in both regular, long and short.
These pants fit true to size if you measure correctly, and wear without other pants. For me, mine fit best either alone, or with a thin pair of capris, not so much with jeans. I love the way they look - not bulky, slim fit.
Believe me, there are NOT a lot of pants out there that fit women "plus-size" riders (I've tried), and these are great b/c of the variety of sizes/inseams offered.

Excellent

Fits slim, which I prefer. No leather so it's good for the vegan crowd. Lots of protection from the ground and the weather. Wish it had an armored back, but that's fixable.
