I've owned this one for a couple years and been pretty happy with it, I can squeeze a ton into it. I think if fits everything you were looking for, minus the removable waist straps. It's held up quite well for the price, but I haven't been on many long hikes to know for sure the comfort over long periods.

Apologies @rikitikitavimeant to reply sooner, like you mentioned those weren't quite what I was looking for but I do remember seeing the moonlander before in reviews, but who knows maybe it'll be an advantage to use a moonlander in the future. 😉 I did end up going with the keychron k3 with optical browns, and just wow... never felt a mechanical keyboard before and this is something else! Just a couple minutes and I'm hooked and can say I get why people really like mechanicals in general. Thanks much for the advice, I'm pretty happy with it already

I would really like more chairs. If possible, can you also do some chairs closer to the $150-$200 range? Thanks.
