for cold weather gear, windproof (Windstopper, Comformax) is absolute necessity. gore tex blocks wind, but is more expensive and not really necessary as staying dry when it's really cold is not a big problem. I'm not nearly the fan of wool that I used to be. expensive, heavy, does not block wind well, bulky. it has its virtues, but we have better options today.

Best hunting coat I've ever owned for cold weather hunting. highly recommend the bibs as well. quality of construction, design, and especially the fit of Sitka gear is second to none. buy once, cry once. this type of gear is a lifetime purchase if you know how to take car of your stuff, and after two seasons wearing Sitka Gear, I still kick myself for not buying it sooner. nothing I have or had compares.
