Ty H.wrote a review of Marmot Col EQ Sleeping Bag: -20 Degree Down on November 11, 2009
Well, I just took this bag up to Alaska for a long hunting trip. It wasn't really that cold - coldest it got was probably mid 20's at night. But I have a tendency to get cold, so I wanted to have a little overkill. And that I did. I stayed quite warm at night, sometimes too warm. And that brings me to one of the con's - ventilating it was hard. I put the zipper down, but would tend to get pretty cold letting in that much air. But if I zipped it up, it got a little on the warm side. Not a big deal, but if you're not going into some pretty cold weather, you don't need this much bag. It comes with a small stuffsack, but I would've appreciated it if it had come with a compression sack as well. It can compress a good bit smaller than the stuffsack size, but it won't stay that small without constant compression. Being down, you must keep it dry. I lucked out on this one as several of my companions got their bags really wet one night and suffered for a couple nights because of it.
