Hi Gabriel; I was wondering where/how you got the cfm rating for the wb400. I can't find that info anywhere. I ask as I'm debating as to whether or not to buy the Mammut Laser jacket which is made of wb400. I'm hoping that it would replace all my other jackets and be one go to jacket for most occasions, but my concern is how windproof it is. Thanks so much. Best, Seldon
