1. McHale PopCan/SubPop pack. Expensive, yes, and not ultralight, but it’s custom made to my specifications, rugged as hell, and very comfortable. Weighs 3.4 lbs, but has several removable parts (summit flap, water bottle pockets, back pad, cord compression system).
2. TarpTent Squall. Super light and spacious. Like a tarp, but without the bugs.
3. Marmot Hydrogen 30 degree sleeping bag.
