As the winter camping season fades in the Mid-Atlantic, I wanted to throw a question out to the community regarding Lightweight/High Volume Backpacks for winter use. For shorter trips with temps down to 30 degrees, I have been using my Hyperlite Windrider. Very comfortable pack, but when the temps sag into the 20's and I need more bulky gear/garments, I have a really tough time fitting my gear.
I have been using my Osprey Aether 85 which fits everything in and then some with no problem, but at 5.5 pounds is over 3.5 pounds heavier which jacks up my base weight. Also, I use this pack in spring-fall when I take my wife as one of the conditions for her to come is I will carry her sleeping bag, pad and clothes. She is worth it. Comfortable pack, just heavy.
But, I know there is always a better way out there. I was wondering what you all use as a lighter pack to haul around a lot of bulk, but not necessarily weight?
