A few years ago my TarpTent Moment's 29 ounce weight was considered UL for a solo tent - ESPECIALLY considering my previous REI SoloLite tent was 4 pounds.
I'm going to hang on to my Moment because it is such a well designed tent but that 16 0z. Skyline X in Cuben fiber really looks tempting to this geezer.
Seems technology and design are always moving the goalposts of what is defined as UL. So now I guess I'm only "Lite", not UL, what with my 16 oz. ancient Thermarest Lite regular mattress, 15 oz. Cabela's PacLite parka, Brunton/Primus Flex stove, and REI Cruise UL pack, and WM Megalite bag.
Ah well, I recently got a Caldera Cone Sidewinder Ti stove W/ Inferno woodburning option. That sucker and its 3 cup pot is very UL, even when carrying a week's worth of ESBIT tabs and no Inferno insert.
Maybe I'll get a lighter mattess in a few years when some miracle UL foam fill comes out. And maybe someone can make a hybrid Spectra/silnylon tent that isn't as pricey or noisy as Cuben fabric. And then there's the possibility of "Unobtanium" tent poles and hiking poles will relieve us of still more ounces.
But the REAL improvements need to come in footwear that is 1/3 lighter than, say, Merill's Moab boots and shoes and just as supportive.
It's always nice to lighten our load but for us geezers it's increasingly necessary as Father Time takes his toll.
