I have a Petzl climbing helmet I use for dry caving that has almost zero foam in it. Gath helmets which I used for wakeboarding, has a fair amount of foam in it. The helmet I wear for scuba diving is an Otter Bay 12mm hood that keeps my head warm 
The LM helmet looks nice! Have found a product they make that doesn't work as it is supposed to.
