Best knee / elbow pro for offwidths?

I've seen folks like Shanti Pack wear some sort of elbow and knee protection, haven't been able to figure out what it is. Would love to hear about people's preferred method of armoring up for off widths. Sent stuff like generator crack without too much scraping but want start practicing on 11ish offwidths in 2019. Thanks!

Thanks guys, very helpful!

Pretty sure Pamela Shanti Pack uses McDavid.

e.g. ​McDavid knee sleeve​​​

Don't get a neoprene elbow sleeve, they are not nearly breathable enough. I am spacing the name right now but get the mcdavid stretch woven elbow thing.

Neoprene works well for knee pads though.
