686 if you want fully waterproof baggie pants. Arsenic or Jibskin if you want that mid ground between a ski pant and a normal pant.
Hot take:
Tbh while I do like the companies, companies like Sovryn they are pretty overpriced and fall back on "its handmade" to justify the crazy price. If they were more techy Ide be bout it, but for >$300 I can get some pretty complex designs that shit on his pants. My recommendation is to only pay that price because you really fuck with what the company is about, not because their designs are worth the price they charges.
I should also say not everything Zach makes I concider overpriced. But his ski pants are ridiculous for the price he charges.
