Question: I'm 15" below the knee and 17" above. Should I get the medium or the large?
Document: I have a pair of large knee pads (different manufacturer) and they work great but a little big so I bought these. I have had to endure bruised knees with every use - I don't like them at all.
I bought these knee pads after my third accident on my bike, when my knees really ate it. The pads have saved my knees over 5 times since. The are bulky and itch after more than 4 miles of riding. But have proven that they can take punishment. With the exception of some minor discomfort, overall they can be comfortable with some adjustment and fit nicely. I'm 5'11 and 185lbs.
These were good for me when I first started skating derby about a year ago. Now that I am more skilled and trying crazier things these are not working! I come home every night with knee pain and bruising now. For the price they were good to start off with but if you are serious about continuing a sport that requires knee pads, invest in a better quality pair. You get what you pay for and knees are not something that you need to skimp on!
For the price you really cant go wrong, you really can't tell there $20 knee pads by looking at them. They don't have all of the bells and whistles of some of the more expensive pads out there, but they have kept my knee's scrape free for a month now.I'm not sure how long they'll last, but they are doing great so far.
These are nice for beginners in Roller Derby or even for more advanced players. One tip I can give is if its between these and a less expensive brand get these you wont regret it
I am a 5'11 170lb male. The Mediums are too small for me. And they are too large for a 8-year old. I'd say the mediums are a good size for an average 12-year old. These are definitely junior's sizes.
great product for longboarding. i just thought that large meant large... should have gotten an XL. over all a nice product:)
I ordered Medium for my 8 year old who is 100 pounds, Fit really well. He is tall and muscular for his age. They take a beating. Kids tease about the pads, but that's ok! He wont have many scars when he gets older. Aloha
I use these for my snowboard where I fall a lot and they work just great, they protect my knees very well. Anyway, the info on the advertisement doesn't mention anything about sizing at all. I'm 120lb so I ordered size S but apparently the size is for children (indicated on package label) in which my size should've been M. Anyway, I force to put them and feeling a bit tight. They should've given sizing info on advertisement as well.
these things are amazing quality for the price! i cant believe i was gonna pay 30 for them! it still would have been worth it... i found them for 18$ through amazon. i'm very happy and confident now that i feel safe!
