Dane, Jhaura, thanks for the r.5 info. Also thanks for the explanation on the 3 vs. the 4. Now it makes a bit more sense.
I have been thinking about two small inner layers instead of a big one, but the Capilene 4 is not bulky at all. Me, I would not spend my money on it, but this is an 8 years old that I plan on taking backcountry where most people would not dare to thread.
When Patagonia says "recycled", are they talking post consumer recycled or plain old recycled fibers? If it is not post consumer, it means nothing.
And Miguel, Where I am is pretty far up north but I don’t think it gets insanely cold up here. Temperatures rarely go bellow 20F during the day. Then again they rarely go above 30F. By most standards that is not particularly harsh, but then the winters wants to last forever, and so does the accumulated snow. This is in the low lands by the Pacific Ocean. Up in the mountains and to the coast of the Japan Sea gets a bit harsher. If you are into snowboarding, skiing, or just want to snowshoe the Hakoda volcano ridge, by all means let me know. It would not be an imposition; I’m always looking for an excuse to go :)
