https://hennessyhammock.com/products/scout-zip$90 hammock, net is sturdy but the rain fly is small enough you need to be good at setting it up to get full coverage, it's very easy to fuck that up. learn your knots, especially trucker's hitch and bowline for setup. it could probably hold up to 170lbs, but I wouldn't go past that. make sure to pack at least 4 stakes to anchor the sides of your hammock and the ends of your rain fly

I have a random walmart 20deg bag, which has been doing great so far. I've used it in -5F before with wool socks and a military surplus wool sweater on and slept like a baby.
tips:
do a set of pushups before climbing into your hammock, not a max out, just enough to get blood flowing.
make sure your hammock is level and staked out to minimize your pad sliding around.
it will take time to learn how to keep a pad under you while sleeping, start out in the summer if you think that will be a problem.
get a pack cover or pack a secondary tarp.
