I'm a big fan of the surplus wool gloves as well. I use them the entire year. When ski touring, those gloves and a shell are all I usually need in the CO winter.
Though I don't use them for backpacking, the liner pants do come in handy for early mornings in my 'truck bivy' camps before I start the actual backpacking trip (thrown them on, make breakfast, slip them off and I am already to go in my hiking shorts)and I do use them for car camping trips when I am, well, hanging out in camp. :)
I also use surplus wool pants for ski touring. I find wool pants to be the original soft shell: warm, breathable, and repels snow. And they are cheap! (Not exactly light..but ski touring is a different ball o' wax...or is that stick of wax? :) )
The last item I use is mil-spec polypro balaclava bought years ago at Sierra Trading post. It is also an item I use all year: Roll it up for a light hat, makes a nice neck warmer or ear warmer and we it down for all around protection.
