Replying to Flylow Snowman Pant

Hello Ladies and Gents ,
This is my first post on here as my old forum shut down any who. Im looking for a new pair of pants and have decided on FlyLow but does any one have any info on the snowman specifically the waterproofness I know it says 10k but I'm looking for real world experience I ski in the east and average 60-70 days . Also in regards to their other pants I've never owned a pair of shell pants how warm are they ? any info is greatly appreciated
