Question: Are these sized for children? I have 2 skinny 11year olds and 1 skinny 13 year old  medium or large?
Document: I bought these for my kids to roller blade. I had a hard time finding the wrist guards that were separate from a set. They are easy to get on and good quality. I got a small for my 8 year old daughter, and a medium for my 10 year old son
My hands are medium size, and the small feels good although the Velcro does not completely fasten. I could have taken a medium but not a large. I didn't want to ride around feeling like I had ping pong paddles on my wrists.
Good solid product however I purchased for my 8 year old, but they barely fit and probably won't last long before she out grows them.
Fits my 5 year old perfectly. I spec big on my 3 year old, but he'll grow into them. Great deal.
My seven year old boy likes the way these look and feel. They seem to be of good quality...  Good value for the price here on amazon.
Bought for my six year old when she started roller blading. They fit well, good quality, and they saved her wrists a few times already.
These are nice, but my 8-year-old daughter found them to be too tight. If your child has a very thin arm, they could wear these at age 8. The sides are mesh and it slides on like a sock. Then you tighten them with Velcro straps. It was the mesh sides that were too tight. We got a set of Razor wrist guards that were the same size but without the mesh and they fit fine.
these are the only wristguards I find comfortable to wear, I just wish they didn't start to fray after 2 or so months, but at least they are cheap enough
Fit well in the large size and I have big hands. Not sure how long they will last as the netting type material does not seem robust.So far so good.
I wore them 5 times and it already looks like they are going to fall apart within the year :(
Answer: no
