I've been using the guide jacket and attack pants (and guide pants late season) for 3 years now. I love them, but if you think that they are for sitting in any temps below 45 or so, you will be very disappointed. And cold.
They are great at what they are designed for - active, mountain hunts. I can push through all kinds of thick stuff, including briars, swamps, thickets, deadfall, etc. with no problem. Still quiet enough to bowhunt with. Light rain is no problem, and they are my choice for tracking or long, long walk to a set up, even down to zero up in Vermont, NY and Maine during rifle season.
They dump heat and sweat as they are designed to do on a high output hunt. They're also very lightweight, stay dry, and dry amazingly quickly if they do get wet. But for hunting out of a tree they are garbage - designed to shed heat, not hold it in. If I know I have a long hike and may want to end up in a tree for a few hours when it's cold I always bring a windproof and insulating layer for both top and bottom (read: puffy pants and jacket)
