Nope, sleep cloths are also an emergency base layer. I don't really like to publish weights, because mine changes every trip. I don't know about the other people. It can get very confusing if I publish 8, 11, 13 all for one trip. Why? (Base weight, Pack weight, FSO weight.) Sometimes I will post 17 pounds. Sometimes 11 pounds. Sometimes closer to 50. These are usually overall pack weights, just easier to weigh once I have everything I am going to bring. What I am doing changes. What season is it? Who am I with? How do I feel? Vacation? Peak Bagging? ...Gear changes, too ...every trip. I try something newwer, drop something old or worn out. I almost always bring long johns, a pair of socks and a pair of under pants...night gear, emergency warmth layer, "In the sheits layer", Bag Liner layer...call it what you will...it is all the same thing. There are a lot of people that use stuff for double duty. Where does it fit in when we talk about it? (Besides the pack, that is ;-) Hmmm, I don't think I even bothered to publish one here....nope. Anyway, that is my take on it.
UL, to me is a philosophy, not a weight. I am not particularly good at it. I STILL carry my SVEA! But, that's another subject. Hmmmm...and, actually, so is this....
I think Brett is straightened out. Without destroying his bag and checking what is happening with the down, I cannot add anything new.
My thoughts only . . .
