I don't wear them often, but have used knee sleeves when I've had knee injuries (thanks leglocks ;) ). Some brand called Neenca, but clearly not very established as they no longer exist. But hey, random Chinese product that did the job pretty well, I was happy with them. :D

I REALLY like the design and functionality of Venum kneesleeves with gel padding BUT they rip at the seams :(

For wrestling my favorite ones have been McDavid volleyball ones WITHOUT non-slip coating.

I don’t use knee pads but I occasionally use a Rehband knee sleeve when my knee is bothering me.

I've been using knee pads for years, and these are hands down best bang for your buck. You can get them at CVS.
