Which is the preferred material for a riding jacket? I need to get one soon. I'm looking at either a Joe Rocket Blaster 2 leather jacket or a Joe Rocket Comet textile jacket. I've tried on the Comet jacket and it feels very comfortable. For leather, what exactly is the perforated leather? Is it basically leather with little holes all over it for good ventilation? Do leather jackets have to be treated to protect the leather from rain?
