I've lowsided on the street twice so far (did around 50 000km in 3 seasons) with 2 different gloves.
A* SP-8 perforated leather, full gauntlet. Still in 1 piece after the road rash only PU knuckle protection rest is double layered leather with foam padding.
I have these gloves. They seem pretty sturdy. I've never had a low side so I can't say how they would perform but they seem pretty well made.
