ykk aquaguard zips and velcro cuffs references back to E's time at Burton in the 2000's. as for ykk i'm certain it's a longtime supplier relationship that's been built since those days
zippered sleeve pockets for snow passes, built-in leg cuff gaiter, floating/detached pockets, self fabric velcro cuffs etc all these design choices being used today are references from his time making snowboarding gear (in addition to the military references ofc). this is what makes acronym, acronym
i would imagine them taking stroll to their giant closet and just have a field day on which features to reinterpret and re-contextualize for the next season *drools*
