Summary: I avoided down for years. I used heavy and bulky synthetic fill bags. I accepted their shortcomings as normal. I kept reading about how great down was and since my 10 and 20 year old synthetic bags were getting thin I decided to try down. I did a lot of reading and decided on Marmot. I got the Arryo first and loved it so much as a summer bag I got the Couloir for a winter bag. Wow what a difference! I have camped in blizzards in Colorado and Wyoming and slept hot.

Summary: I have used this bag in temps ranging from 5 degrees F to 50 degrees F (more as a blanket at that point). Let me first say that the bag is warm and quite comfortable and if there were no design flaws or customer service issues I would highly recommend the bag. At the very lowest temperatures I have used the bag in, it has kept me warm other than a very annoying problem with the draft tube designed to insulate against cold air coming through the zipper.

Summary: I've used the bag a few times but never below 40F. It's comfortable and has kept me warm. However, because I am a cold sleeper I will probably never use it for winter camping. I have a mountain hardware ramses w/ stormlight that seems warmer. On the down side, expect for this bag to lose down. The bag constantly loses down through the bag's inner and outer shell. It's probably not enough to affect the warmth of the bag, but it sure is annoying.

Summary: I have a love/hate relationship with this bag. I LOVE its construction, its advanced and very high quality materials, its generous cut (I'm 6'5" and weigh about 275 and this thing is cavernous even for me) and its warmth and coziness. Though I haven't tried it in true winter conditions yet, its has kept me toasty warm at 40 deg. F. Anything above about 45 and you have to open it or it'll be too warm.

Summary: Excellent cold weather bag. Great loft for very little weight. The shell material is very light weight, so if you intend to use the bag in wet conditions I suggest looking into the Dryloft version. If you like to stay dry (i.e. not climb in the cascades) then you can't go wrong with this bag.
