The Big Three: what specific gear (not just brands) do you use for your three-season shelter system, sleep system, and backpack? (It's okay if it isn't ultralight!)
I have an REI Quarter Dome tent (2 person). I use the REI Halo (10 degree) bag in colder months, and a lightweight Kelty for warmer months. Pad -- Them-a-rest ProLite. And pack -- Osprey Aura 50.
