i know with the drop of first drop line and the claims that 8k is just as good as 20k. well i think there might be truth to this.... today i was messing around doing a little skiing and sledding in all the snow we been getting here in Golden. after i got back from a good day of messing around i noticed that my saga jacket (20k) was slightly wet when my Oakley pants (10k) were bone dry. both of these are pretty much brand new so i don't think that makes a difference.
so idk about others experiences but i dont really think there is a difference between the two
