Reddit mentions of Outdoor Vitals Ultralight Hammock Bug Net with Underside and Side Splash Protecton (Black, 11 Foot)

I have this bugnet and absolutely love it, but it's not bottom entry it's a sock style. It's only $40, and weighs only like 0.7 more than Dutch's for the 11 footer.

If your hammock already has a ridgeline, you could ditch the included shock cord ridgeline and it would probably be the same weight as Dutch's, actually.

1. Get a hammock with straps, not rope. I recommend this one because it's cheap and includes the straps, plus it's 11 feet long (as opposed to less than 9' for an ENO. It's heavy and wide, but you aren't backpacking with it, so that's OK. https://smile.amazon.com/gp/product/B01M1F1IZU/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
   
   
2. A lot of nights, you won't need an underquilt - until you do. I went camping on the 4th of July last year and was sweltering when I used mine. Ended up pulling it aside. Sure enough, about 4am, I was "freezing" at about 70 degrees and pulled my UQ back underneath. Get a 1 Season Jarbidge from Arrowhead Equipment or get this cheapie from Amazon - note that this is cotton. Not something I'd recommend for longevity or for backpacking, but it should work for a summer.
   
   
3. I'd shy away from camping top quilts as most of them aren't very breathable. They're designed to keep you warm and block wind. A traditional sleeping bag can work, but if it's nylon on the outside you're going to sweat like mad and that condensation is going to stay with you. Instead, try a cheap fleece blanket. It'll breathe and should be all you need for most of the summer. Switch to a 40 or 50 degree bag from walmart if you really need to go that low.
   
   
4. For that matter, stay away from anything down. Others have already mentioned the humidity. And it won't be cold enough to warrant spending the cash on down, anyway.
   
   
5. Mosquitoes suck. Get a bugnet. This one from Outdoor Vitals is inexpensive and will cover you on both sides, so the mosquitoes can't bite you even if you aren't using your Top Quilt/Under Quilt. It'll also add a couple of degrees on insulation, which kind of sucks sometimes, but helps others.
   
   
6. Keep a beanie with you. I keep my hair really short and I need one anytime I'm sleeping outside below about 70 degrees.
   
   
7. Misc. stuff - This isn't strictly necessary, but it's nice to have. Go to Dutchware Gear and get continuous loops, a ridge line, and a ridge line organizer. The ropes on that hammock are super bulky and heavy. I hate them. The ridge line will help you hang your hammock the same way every time, and will help make sure you have enough sag to get a nice, flat, diagonal lay. The organizer should be obvious. I keep my headlamp wrapped around the ridge line itself (Zebralight, check /r/flashlight for more good options), my phone in one pocket, knife/etc in another pocket, and a water bottle in the hammock pocket.
   
   
8. Get some good earplugs. Depending on where you are, you may want to be woken up in the event a 2 legged critter is approaching. If you don't worry about that, then the cicadas, crickets, and bullfrogs will keep you up until the roosters start crowing and the dogs start barking. Or maybe you'll be by a highway. Foam plugs are cheap, but I find them uncomfortable. Amazon sells some that you mold to your ear, but I haven't tried any of them. Instead, I visited PMS firearms and had "Granny" make me a set that fits my ears. They're the best I've ever used.
   
   
9. Edit: Forgot a tarp. I use this Chill Gorilla because it packs up small. If you've got the space, though, it's just as easy or easier to buy a 9x12, 10x12, or 12x12 tarp from walmart. I've used both this one and this cheap blue one and both are fine, strung up with some cheap paracord.
