It's because 98% of the market is insulated 5 and 10k jackets that soak up wetter snow and do not fit a helmet. Storm skiing for my kids is not as chill as it should be. they've got face buffs, but...

Most I see are insulated, < 10k rated or not rated, with hood designs not friendly to helmet.

pretty nice looking kids shell there. Anything similar where the hood works with helmet and face coverage is good when zipped up?
