I rock the Motoport Kevlar Racing gloves in the summer for all temps and such.
Personally I think motocross gloves are about as worthwhile as wearing gardening or mountain biking gloves. At even reasonable speeds, I'd think they would shred.
if it's going to be cold or get cold, I just put on my regular leather Helimot gloves, or for wet use, I put on the Aerostich lobster claws.
