Winter gloves

[Grahamm]

Bike glove give just about no protection when you fall off - the palm leather is usually wafer thin

Hmm, I have a pair of Alpinestars now and an old set of RSTs which I used previously and both have decent leather on the palms, plus extra padding for the "impact areas".

The dive gloves are either 3mm or 5mm crushed neoprene which is tough as old boots and it gives quite a bit of padding over the knuckles . I think they would give better protection when sliding down the road

Fair enough, it's your choice.
