Did a trackday with the GP Pro in the wet, hands never got wet in the rain. Use it only on trackdays and so havent used it much. I think the leather needs breaking in.
One advice on A*. If you have big hands, always opt for a bigger size. My first A* was a MX-2 or SP-2 (cant remmeber, the short glove). Bought L since it fit my hands even when i curled up the fingers. Once I wore them and actually held the handlebar, it became way too small. My little finger hurt really bad and the palm opposite to the lil finger was hurting bad. Couldnt use them unless I dont zip them up. Ultimately they got torn off on a crash on the track.
Since then got a XL GP Pro, it feels bit loose when worn but fits nicely once you hold the handlebar.
