Hang Tight?

I’m looking to upgrade from my Amazon hammock underquilt (Wise Owl) and my Kelty Cosmic Down 20 degree bag.

Is the Hangtight Heat Seeker 20 degree top and underquilt set worth it for an upgrade? Spending $500 plus is not in my budget like ever to go with something else hahaha.

I also want to buy products that are ethically sourced. I am also attempting to buy more PFAS free gear when possible. From what I have gathered from the owner is that the down is ethically sourced, and the materials are also PFAS free. Anyone have any other info on that? I feel like I have badgered the guy with enough questions.
