WYATT F Whoops, I accidentally reviewed the cheaper Aleutian 20F sleeping bag in my review. I bought both recently. I haven't used the Aleutian 3S 20 F bag yet, but it seems to have some of the same characteristics of the 20F Casaval sleeping bag which I already have. So, sorry about that.

WYATT F This is a budget priced sleeping bag that is higher quality than some of the other budget priced bags out there. I bought this one to keep for emergencies, not to use regularly. If you are going to use your sleeping bag regularly and would like it to last several years, I would recommend buying a slightly higher grade sleeping bag, such as the North Face 20F Casaval, which has a more durable nylon outer shell and has more refined features. Darker outer shell colors are also more desirable as they don't show the stains that inevitably come with camping out use of your sleeping bag.
