happyGeorgie, your first post - Welcome to the forum. One phenomenon that surprised me as I started posting on "gear" forums, like those dealing with hammocks and kayaks, was how often the notion of "best" was mentioned. Like, there is some absolute golden item out there that, when obtained, would stand forever.
Best in the summer is not best in the winter. Best for someone who is 6ft+ is not best for someone who is 5'6". Best this year may not be best next year. Best for me may not be best for you. But...we also have common phrases, and it's easy to toss out, "What is the best ...?" with the idea that we can minimize critical thinking, pay money, and the item will be fine.
Please understand that I'm not trying to be harsh - it's just an interesting phenomenon.
So you just got the WOO hammock - you have two considerations: a bug net and a ridgeline. I encourage you to read what has already been posted about a ridgeline for your hammock. It is a cord you add running from one end of the hammock to the other. Its job is - after you've set up your hammock enough times to establish the best sag for you - to provide a reference setting so you can return to that ideal sag each time you set up, rather than figure it out each time. Your hammock has a physical length - usually about 11 feet. You hang it so the ends are closer together, creating a sag that allows you to turn a bit diagonal to the hammock's center line. For an 11-foot hammock, the ends would be about 9 feet apart when hung. Hammocks with built-in bug nets already have a ridgeline. For a hammock without a built-in net, you can add a ridgeline or not. It's not mandatory; it's just a convenience for some.
For the bug net, there are two main choices. They all encapsulate the hammock with the hammock suspension running through an opening at the net ends. Those openings have some kind of Velcor®-esque closure. So they are not an absolute seal, but usually good enough. The main difference is in the entrance/exit. Some have a full arch zipper. The only way in/out is to open that zipper. Others have a cinch opening at the bottom. You just walk up to it, lift it up, and drop it over your head. The opening usually has a drawstring made of shock cord. The idea is, when you are in the hammock, that opening is pulled up against the bottom of your hammock - blocking the ingress of critters.
Which design is best? T'were it me, and I didn't have a hammock with a built-in bugnet, and I was in a known bug hangout, I'd go for the full zipper closure. It's almost foolproof/absolute (except for that Velcro® end issue). But you do have a mechanical zipper that can fail. And it is a bit bulkier and heavier than a net without a zipper, but perhaps by only a few ounces.
You can purchase bug nets from vendors such as WarBonnet, Dutchware, Hammock Gear, and Grand Trunk, among others. Just Google "Hammock Bug Net".
I have no experience with it, but I like the design of the Grand Trunk Mozzy because it appears to create a sheltered area outside the edges of the hammock so you can sit in the hammock or stand next to it to get dressed and still be inside the netting. Again, you are trading weight and bulk for convenience.
But honestly, if I was going to visit an area where insects were a real concern, I'd take a hammock with a built-in net, and I'd probably treat the net with Permethrin. You might check with some locals in the area you'll be staying. Ask what they use and what precautions they take when out of whatever sleep shelter they use.
Understand that many videos you'll watch were made by Thru-hikers who have priorities like less bulk, less weight, and for whom the occasional mosquito is a nuisance, not a health risk. If being bitten while you are in Asia can have serious health consequences, not just an annoying itch, then you'll want to prioritize maximum reliability and coverage over less weight and bulk.
