At 80 and well into geezerhood I’m getting into even lighter gear than when I was in my 60s. An Osprey EXOS pack, REI Flash 3 season insulated air mattress, WM Megalite down mummy, TT Notch Li Dyneema solo tent, Crux folding canister top stove etc.
Yeah, there are lighter packs but I love the comfort of that pack, and smaller mattresses but again, comfort. The Notch Li is a double wall but the interior is extremely light and totally bug proof plus adds a bit of warmth and keeps out dust here in the southwest.
It’s things like a SPOT rescue beacon and light but rugged waterproof  Olympus TG4 camera that add those extra ounces. My medical kit is smaller and I’ve often left my SteriPen at home using only Katadyn chlorine dioxide tablets and a few #2 coffee filters. At altitude I know I need my light down “sweater” and can use it to sleep in if it gets down into the 20s F.
One spare briefs and pair of socks, sleep shirt, eVent parka and no wind shirt. nylon baseball hat or “desert hat” with new protector. All clothing is synthetic B/C I don’t like wool’s sweat absorption.
Th-th-that’s it folks. Any suggestions, especially from other backpacking geezers? (besides a lighter rain parka)
