I bought these a couple months ago for some extra protection commuting to work. These are extremely well designed external armor.

Pros:

-Affordable

-Great materials: This armor is dense, but still manages to breathe fairly well. The stitching was to the high-standards I expect from Dainese.

-Ergonomic: Each guard is specifically designed for either your left or right leg and fits extremely well.

-Articulation: The multiple joints built into this help provide further protection and also comfort. The armor is layered like scales so that you do not sacrifice safety for flexibility.

-Coverage: Despite the name, these are much more than knee-guards. They cover the full length of my knee, not just the kneecap, and then end at the point my Stylemartin Indian riding boots begin. They're slightly tapered so that they can either be laced into or placed over a normal road boot. They also seemed fine with a pair of storm-trooper boots a buddy of mine tried them on with.

-Sizing: I have no idea what the people complaining about these being too small are talking about. The straps have a ton of extra-length and the jointed armor design provides a good fit for all of my friends who tried them on. This includes a guy who is 6'2" and has freakishly muscular legs from playing soccer and mountain biking.

Cons:

-Heat: I live in a warm climate. These things will make your legs sweat above 85 degrees, but they have about as much ventilation as possible considering the density and quality of the armor. It's a trade-off, but I believe it's worth it.

-Straps: Dainese decided to use velcro with these, which while fairly convenient for taking off quickly, is personally a bit of a pain. I'm a fit guy and it definitely seemed like there could have been a bit more of the fastener material. The middle strap can also occasionally dig into your leg a bit if you ride with them as tight as I do. My suggestion would have been d-rings with a clasp mechanism, and I may still end up replacing the stock straps with something along those lines.

Over all, these are excellent and definitely the best choice for leg armor at this price-point. If you're overweight, obese, or have thunder-thighs, this isn't the product for you, but I don't know why you would expect an Italian manufacturer to be in the business of plus-sized equipment to begin with.

Anyway, I don't write reviews that often, but these definitely deserve my endorsement. They look cool, are convenient to carry with you considering their size, and are also a ridiculously good deal. Buy these things, you'll be glad you did.

Had a 20mph lowside on a chewed-up old asphalt road today while wearing these and Alpinestar SMX5s (screw you, deep sand washout). They held up admirably and saved my knee from what would certainly have been a nasty gash. I was always a bit concerned they might twist off in a crash, but they stayed nicely in place. One of the little plastic loops you thread the velcro through took direct impact and is still good to go.

I've been wearing them for about a year now, and they're super fast to put on/take off. I don't even notice them when walking around; they're quite comfortable. Definitely worth the money.

I use these under my riding pants. Putting them on takes about 30s per leg. They can be worn for hours on and off the bike without a problem and they don't hinder walking.

Unlike the typical protectors integrated to riding pants, these stay in place and cover the knee and shin in every leg configuration.
The sides of the knee are not as well covered as the front, but that seems to be the case with most knee protectors.

*My review is actually of the previous (now discontinued) version, the Dianese Knee V Guards. As far as I can tell, they are essentially identical.

I bought these guards to wear under AGV sport kevlar riding jeans, and they fit and work very well. They are reasonably comfortable, and extremely robust. They are substantially sturdier than the armor that was included with my Dianese New Drake Air textile pants, and I have no doubt they'd offer excellent protection in a down.

The velcro straps are about as comfortable as can be expected. They are much more comfortable if I take the time to get the tightness just right and be sure the velcro is completely mated. If not, then they'll be somewhat uncomfortable either because the straps are too tight, or because the stiff side of the velcro will irritate my leg. If I take the time to put them on carefully, neither is an issue.

I've worn them for 6-8 hours of riding over a day, and by then end of that, while I was ready to get them off, they were as comfortable as could be expected.

I've been commuting in these to and from the office for about a month. I bought them originally thinking they're gonna be super easy to slip on and off but the protection goes probably 2 inches above the knee so there's no easy way to put these on by hiking up your pant leg. The knee guards arent overly bulky but i still have to drop them down the pant leg from the top if im at the office and then tighten em up in the bathroom.

With that said, they're super comfortable, fairly low profile under dark jeans and i didn't feel anything dropping down on my knee from a foot or so off the ground.

I wish there was a little more protection on the side of the knee. The hard plastic covers the front but very little on the side.

They extend about two inches into my midrise boots. The guards are 17 and a half inches top to bottom.

Love the look, and the strength of these pads.
Hopefully never have to test them - but the idea is that they will hopefully stay in place in event of a crash.

The three straps really help a lot - and also are comfortable.
I wear them on top of my jeans - and since they are black they dont stand out much. Dont think they will fit UNDER my jeans -

all in all - i think - for the price - these are amazing.
And i definitely recommend them to everyone.

Two things you should know about these

It's great to have extra knee armor like these, but having crashed in a similar product, they will begin to slide out of position after the primary impact. They also don't include much armoring on the sides which is kind of surprising. Just know these aren't a replacement for leathers

But my biggest issue with these is that they don't include pre-adjust strap snaps. People wear these things to add protection to jeans in normal situations. So you get to the bar, you tear away the velcro on each strap, and there are 6 velcro straps. To put them back on, you thread them through the loops, back around, etc. This is anooying, especially if you have multiple stops to make.

Other manufacturers secure a male snap to the straps, and a female to the guards, so each time you use them, they snap right back into place. This seems to make a lot more sense. Why Dainese missed this a total mystery

I bought these a while ago and was super excited about them. They do feel very comfortable when being worn. They do not fit underneath any of jeans so I just wear them over my pants. The first day I got them and decided to test them out on the road. I'm about 5'10" and 168 lbs. I Strapped these suckers on over my pants and just fell right on my knees letting gravity push me to the ground. These things absorbed the impact very very well. Was able to feel the energy travel through the armor and some of it travel up my leg but there was no pain. They are now a little bit scuffed because of that but they still work fine.

I do not know how well they handle during an actual crash because the velcro strips could just undo themselves while be tossed around if worn over your jeans.

Besides from the obvious protection these offer, I found that they are just great protection for your leg against rocks and pebbles that come flying at you. They have helped keep me from warm during the cold weather we are having right now which is a plus.

They take about maybe 1 min to put on which is not bad.

I think they are great. I always wear them when I go riding

I am really pleased with the quality and design of the knee guards. They provide good coverage of the knee and shin and is thin enough to wear underneath jeans. These will replace the built-in knee pads in my riding jeans. What's great is you have the option of strapping them on top of your pants. The hard shell and padded liner are comfortable with no pinching.

Great Protection for the knee and shin. I feel like these will do well in the event of a fall. Knock on wood. Revzilla, excellent service and fast shipping. Ordered these and they came the next day. Amazing. I would definitely buy these again.
