^yes the mm does have everything to do with how long it lasts.
see in order to get a higher mm you have to add more to the jacket. hence a higher mm. how could you have a 200mm last for 2 years? its not possible because the reason its 200mm is because you barely applied any spray or laminate. you could easily double up on the spray and laminate and get 400mm, in turn lasting 2 times longer because their are 2 layers of the spray.
so how can you say it has nothing to do with how long the water proofing will last?
its simply physics man, get with the program.
the more spray you use the more it gets into the fabric, the longer its going to hold in the fabric, keeping the user dryer longer.
bam... yeah that was simple physics in my mind
