My brother worked on a oil rig in Norway were they give out the best equiptment in the industry. He was give some vibration gloves and realised they would be great for me(£48.00 a pair!!!!) so i have used them for about 4 months now and there the best gloves i have ever had.
The grip is like leather but with a small amound of sponge under, there not waterproof as such but my hands very rarely get wet. Really comfy gloves for the summer, i will let you know how winter goes
