Great, very comfortable
Im almost 6' tall, long arms, trim to average build 185 lbs. My arms are bigger than legs. XL size for arms and legs slightly large for me, almost perfect over clothes. Certainly workable with velcro straps. I could use a large without clothes underneath. Glad I bought XL for versatility, hot or cold weather use. I cant imagine better fit, comfort or protection in more breathable fabric without rigid plastic...worth the price, always worth the protection. No doubt they do truly "save."

This is the best knee pad for biking
I have tried almost every pad made for biking: POC, G-FORM, Fox D3O, Troy Lee, etc. This offer the most comfort and best protection out of all of them. They are very similar to the Fox pads but the fox pads only come in 3 sizes and I was between M and L on those. Additionally the fox pads seemed to have a large empty space between the pad and my knee cap. The Large Demon pads fit my leg perfectly. Its comfy, and there is not a lot of excess material/space. I am 6'1" tall and 160 pounds. My knee measures 14" directly around the center of the patella, and my thighs taper very quickly as you go up my leg. My thigh is 16.5" as measured 4" above knee cap center and my calves are about 13.25 at the fullest part. On my leg, the top strap sits more like 2" above my knee cap center, not 4". This pad has an angled lower strap which allows it to rest just above the belly of the calve to prevent slip down.

I would recommend these to anybody looking for a good pair of pads
I have been researching knee pads for weeks upon weeks, watching videos and side by side ratings from multiple mtb forums, I decided I would try these out since I run their helmet and A fan of it. So here is my opinion, Fit is perfect and super comfortable. Some people have said that the sizing isn’t true, just learn how to measure things and you will get the right size, adding a inch to your size doesn’t always help you. Product and packaging are nice quality and they come with a mesh bag which is nice for keeping them together and helping them air out and get that stanky sweat off that has been beholding up all day. I would recommend these to anybody looking for a affordable set that still offer good protection.

Amazing Product
As a first year snowboarder I’ve fell a lot. Moving into the terrain park was a lot harder than it looks and this product, while not limiting flexibility, has saved my knees many times!

Great value
I find these perfectly comfortable, they have been durable. For the price I 100 percent recommend.

Excellent fit , Great protection
I am 5’10” average build. I bought an extra large set of knee pads. They fit perfect. Very very comfortable . I had them on for 5 hours and could have worn them on our drive home (3 hours) they are so comfortable. I don’t even need to tighten the Velcro. I bought these over other brands because of the Velcro just in case. I crashed hard at an indoor bike park ( wooden ramps) my first time using them. I landed into the side of the ramp on a sharp edge. These pads held up. No rips or tears. I have no doubt my knee would have been really messed up without this protection. Just for clarification, I’m a 50+ y.o. guy. I’ve ridden bmx and mountain bikes my whole life. Crashes get a little harder to recover from the older I get so I wanted some added protection with comfort. I looked at 3 other brands and kept going back and forth. I finally decided on these. I am completely satisfied

Not very comfortable and the protection is not good
Purchased for couple of years, I now enter my third snow season and finally get rid of it. The gear is not very comfortable because the inner pad edge is cutting my leg which feals hurts. The protection is also questionable, I really start snowbroading my second snow season, I fall down a lot. When I back home, it's bruised all over my knees.

Best knee pads ever (for skating)
I’ve tried like 6-7 different sets/brands of pads for skating and these are perfect (even though they’re made for biking). They’re super flexible and comfy, I barely remember they’re there. They’re also slimmer than most knee pads and yes, I have taken a good amount of falls on smooth and rough concrete, rocks. No problems and barely felt anything tbh. Def buy the size recommended with proper measurements from the brands site! Don’t size up or down. I’m 5’11” 150lb and I wear a medium in knee and elbow. The medium could probably fit someone a bit bigger than me bc there’s still room in the tops of mine. However, there’s elastic that you can get a snug fit with and some gel grips in the tops that grab onto your skin to prevent sliding. 9/10

Excelente producto llegó antes de lo planeado. El material no le pide nada a las Fox D30 que son del mismo segmento, costuras, elasticidad y tamaño. Mido 1.85 y peso 104 la talla L me quedo bien, en su justo medio y son ligeras al momento de rodar da la sensación de no sentir que las traes puestas

I was using some no name brand for snowboarding but they are nothing comparing to the Demon Hyper X D30 kneepads. They provide a lot better protection and also comfortable to wear all day at the same time. Even in icy condition my knees are protected when I fall. Will purchase again in the future for other products.
