You’re welcome! Yes some leather outer is for sure beneficial to keep moisture and winter mud at bay. The Northwolf I have must be impregnated around the sole, but the wool outer with the membrane should do a good job at keeping me dry. The wool is sometimes underrated and can be very dependable, but traps dirt much more than leather or other smooth surfaces. The Peerko look classy! I don’t like side zippers personally, but they look solid. The upside for the Scott for you would be, that you already know that the sole shape (from your Primus) is a good fit for you. But this shouldn’t stop you from trying other brands :) Best luck with your minimal shopping!
