I see UL and SUL backpacking as a blessing for the more senior of us. Let's face it, as one ages (and stays in decent shape) strength will inevitably decline, as will oxygen uptake/VO2 Max.
At 68 I'm going more and more toward true UL backpacking. And I know that as I advance into my 70s I'll have to get into some aspects of SUL backpacking. By that time I'm hoping for more SUL gear to chose from that is also more durable.
Right now I have my major UL big three as:
1.TarpTent Moment
2.REI Cruise UL pack
3.Western Mountaineering Megalite down bag/15 oz. ancient reg. Thermarest Lite matress
4.Caldera Cone Ti Sidewinder stove (W/3 fuel options)
So, yeah, the tent and pack can be a lot lighter. Workin' on that.
I am still not a fan of alky stoves so I use ESBIT or wood (when permitted) W/ my Sidewinder stove.
I'm a real tent fan, having tarped "too much" when I couldn't afford a tent. But I can see getting something like Ron Moak's new Skyscape-X tent in Cuben fabric. UL solo tents seem to be more efficient and at least as light as say a Cuben tarp, groundcloth and bug netting.
As for a pack, maybe a Go-Lite Quest. I eschew "frameless" packs as much as alky stoves.
And the mattress? I'm waiting for a Cuben mattress with Aero Gel for a filler.
(Aren't we all? :o)
