User Review: Marmot Col EQ
Price Paid: About $510
I have used this bag for several years in some nasty weather and conditions. It is just exactly what they advertise.
I do not climb, but camp in the snow often, and have been very satisfied with the performance of the bag. When it is around 0 I don't even think about being cold at night.
Having spent much of my time in the woods and mountains of the Northwest, I don't go without it. I have spent nights that lasted forever in cold bags, and bags there were damp. Those lessons are tough enough to be on your mind when you go shopping for a new bag.
You will whine at the price, but not at the performance. Complain about the price on the way home.
