I have been using the same one, but the netting on my face bugs me. I might string a paracord line down the center and tie off to it.
I didn't know you could request the side zip....that would have been nice.
I'm not 100% but I think he will take special requests, I think the paracord could help but also create new issues.
It probably will create some new issues especially as much as I move while sleeping.
Maybe a short thin carbon tent pole to make a "hoop" over the face area would work.
I use a ti-goat bivy under my para-tarp. The netting you just kinda get used to. I could probably get away with no bivy sack at all just a ti-vek ground tarp. In the area I hunt we usually don't have many bugs, but it's just one of those things I don't want any creepy crawlers around me.
This is really the first time I have used any kind of bivy under a tarp. I'm going to be in some areas this year with a lot of mosquitoes (so I hear) so I figured I should try getting used to it.....so far I prefer it without, but I don't have any mosquitoes flying around right now either.
