Big Agnes Copper Spur HV UL2 vs Six Moon Designs Lunar Solo

Regarding the question of floor size. Apart from weight, one of motivations for 'upgrading' from my 20 year old tent (that I also loved) was because my partner was insisting on having a bit more interior space, especially for the longer treks. Before purchasing, I measured out the advertised dimensions on my garage floor and saw that my old tent was well inside the boundary limits, the CS UL2 had plenty of extra width and length when compared. And yet on the trail, there wasn't as much space as expected

We spoke about dimensions and what not because it seemed like lots on this sub had trouble fitting at my height and setup (6'2", LW 3" pad, pillow), and you let me know that eventually there would be a V2 that was longer. I needed a shelter quickly so I went with the Lunar Solo which I've been mostly pleased with, given that I use my second pole for the head guy-out and often a stick for the foot one too to increase volume.

We use this for two of my kids when backpacking. Very reasonable weight when split between two people. If you want to still be in one tent as your kid gets older, though, a 3p tent may be a little tight.

You could save some weight by changing out your sleeping bag and maybe even your pack (unless you absolutely love it). I was in the Sierras in August 2019 with a 15 degree mummy and in June 2021 with a 20 degree quilt and I was happy to have them.

A couple of my friends have the previous version of this and having experienced both, the 2020 version has some cool new features:

There are three great things about this tent. First, it weighs 24 ounces. Second, interior floor space is big enough for me and all my gear just fine. Third, you can buy it on Amazon, which means your family could give you gift cards you can put toward the purchase of ultra light weight hiking equipment
