of bug netting

Mosquitoes can bite through any relatively loose weave fabric if it's touching the skin. On a recent trip I had numerous bites on my shoulders even while I was wearing a long sleeve merino wool shirt. I had to put on my wind shirt to keep them at bay.

Yeah, I just finished making a modified version of the meteor bivy and the same thought game to me while I was laying inside of it in the back yard. If it's a warm night and the momentum 90 is draped across my legs, could a bug (mosquito or otherwise) bite me through it?

It really varies for the product. I've never been bit through my wind pants, wind shirt or rain gear. A regular cotton or wool shirt (or socks) is a different matter. The original bug shirt (http://www.bugshirt.com/) uses a very tight weave fabric (typically cotton) for the part of the clothing that sits against the skin. At the same time, they design the netting so that it doesn't touch the skin. The bugshirt isn't perfect — it is hardly ultralight and the netting is traditional netting (not nano-seeum). For most trips, I typically use rain gear or wind gear combined with a headnet and bug gloves (made by a company that is now out of business).

It wouldn't surprise me if Momentum 90 is OK against bugs.

I have never been bit through a Meteor Bivy. I do often sleep in it on top of my bag when it's warm out. I guess bugs can't bite through the tight water replant fabric. I also hang the net high above my face so no bites there.

I have been bitten through light nylon hiking pants and light baselayer shirts, but never through windshirt or windpants.

One of the many reasons I carry a windshert and windpants.

Does anyone make a bug net bivy that is freestanding-ish? I don't take trekking poles and trees are not always available. I would wear the windshirt stuff but I think that I would be a bit warm above 70F in it while trying to sleep. I will have to see though as that is an option.

Adventure 16 has a bug bivy with spring loaded wire kinda like those car windshield shades.
I am not sure if they still sell them new but i know i have seen them for sale on used gear sections of websites.
It is a smaller bivy that is designed to just cover the upper half of your body. From what i understand you get into you sleeping bag and pop the A16 bug bivy open over your head and thats it.
The other option is to carry extra cordage and simply hang a standard mesh bivy from tree branches etc.
You could also stuff your backpack and gear into the head end of a meteor, serenity, or minimalist bug bivy to hold the mesh off your face.
I met a few other Long Distance hikers in the past few years that simply wore a head net over a baseball cap while they slept. I tried it and i also needed earplugs cause those little bloodsuckers can make quite a racket! I use a Bear paw Wilderness Designs Minimalist bug bivy now but i hang it from the hooks under my Patrol shelter of from my trekking poles in "stand alone" mode
Sounds like the A16 is kinda what you want though.

Wow bummer! I found one that just sold on BPL a short time ago for 35 bucks!
Anyhow I swiped the photo from the BPL ad to show you what the A 16 looks like.

You can also use found sticks to hang a bug bivy off your face.
Since you don't need much, you can run lines between two bushes.

A tripod made of sticks is quick and easy to tie. Google "boy scout tripod lashing".

I want to thank everyone for the help so far but I am looking for something more for the 70F+ temp range where I will not be using a sleeping bag and might just be in some shorts and a T.

Are you using trekking poles?
Or would you consider dedicated shock-cord sections?

If so, a basic tarp pitch will get the job done.

Imagine the netting staked to the ground, but with a 12" flap all the way around, extending Out from the NetTent. (Put the stake loops on the Inside.) Poles at head and foot take care of the standoff.
