I got to spend some time withe folks at Patagonia (Golly, were they nice!) who showed me some of their Spring 2013 Men's alpine line.
M10: As I mentioned in an earlier thread, the M10 is making a comeback in Spring 2013. I had assumed it would come with Gore's active shell, but it comes with the 3-layer, 15 denier H2NO that was in the prior M10 (which was very, very breathable). The new m10, while 3 oz lighter (7.9 oz), lack's pit zips and comes with a sole chest pocket, which it stuffs into (comes with a carabiner loop ala Houdini).
Das Parka: The Das Parka is being updated with 120 Gs of PL Synergy (which is supposedly the top tier PL insulation, warmer than PL one) throughout but with an additional 60Gs of PL one on the chest, hood and parts of the arms- making it SUPER warm.
Better fit, (somewhat slimmer, it seems), dual zips, same pocket set up, and a hood that is similar to the Down Hoody. Also the exterior fabric seems new, a lot like the Ultralight Down shirt. Weights ~22-24ozs.
