MLD Solomid Interior Options

Personally, I like using a bivy under a mid. UL ones with netting around 7 oz are nice insurance against bug pressure plus add some warmth to your sleep system. It will also act as your ground cloth so on a net basis compared to just using a ground cloth you are adding something less than 7 oz with the bivy (maybe 4?).

I like a net tent wayyyyyy more than a bivy. They can be similar in weight with the net tent being a few oz heavier tops.

My net tent from SMD weighs 7.9oz in a stuff sack! That is a great weight. It is very nice to sit up in the net tent and read, change clothes etc. In a bivy thatss impossible unless you unzip then mosquitoes will eat you.

i have yet to understand the preference for a bivy when they pretty much weigh the same. I mean, my MLD solo innernet is 6.7 oz – and most bivies i see are that same weight.

So what's the plus side??

Extra warmth.
Adds 5 to 10°F to your insulation.
Stops wind better than net tent.

I'm not a big bivy proponent, however I use bivies, as well as a net tent, and each has its place, depending on the conditions you are about to encounter.

Winter – mid with bivy.
Summer – mid with bug inner. I also use bug inner only.

I live in the east with the bugs. Out west, I might even just do mid with sheet.
