For BOBs I usually have a couple of large duffel bags that allow me to carry all the fleece I could reasonably use. I'm not planning on hiking anywhere with them, if I go it will be by truck or with a cart, so limited mobility isn't an issue.
Backpacking I use a huge external frame pack that allows more room than I ever need. I can carry my sleeping bag, any of the tents, a tarp inside it and still have room inside for all my other gear and a second sleeping bag if need be.
I seldom use them but on a lark I got a couple of ultralight compression sacks on sale at a local pack shop. Pretty neat. Using them I can squash down even an overly bulky, and not very efficient, Coleman sleeping bag to about the size of a loaf of bread. These are tough stuff sacks with bands going in both directions that allow anything inside to be squeezed down to its minimum possible size.
It doesn't take long as the buckles operate only one way until a tab is pressed. The biggest has six bands lengthwise and four around the circumference. A quick pull on each strap in turn and twice around both ways, takes about a minute, and it's done.
I like fleece. It is warm for the weight, cheap, doesn't hold moisture and it lasts a long time. A base layer, fleece mid-layer and a rain jacket and pants as outer layer to keep wind and rain out and I'm good for anything nature can toss my way. last I priced it the a complete outfit, including some poly/wool socks and liners was about $100. About a half what one of my mates spent on just his jacket.
The jacket he is such a Nancy about because he doesn't want to get it dirty or muddy or risk it getting torn on thorns or too close to the fire or spotted with pine tar or bug juice. Funny guy to camp with.
