Any thoughts on this model vs the WP model as far as warmth/durability? i.e. is the non-WP model ligheter/semi-permeable/breathable? Mostly curious for colder winter months here in the snowless southwest. Also do the shoes fit true to size? I am on the bigger end of the size spectrum and am concerned the 12.5 might be a little short. For reference I generally wear a 47 in La Sportiva shoes. Thanks for any and all the help you can offer!
