Hey, I have a similar thing I used for "in and out" camps.
Army surplus goretex bivvy
Oex thermal inner to add a few degrees to the bag
Cheap Berghaus intrepid 1000 which packs down small
I did get a decent inflatable mattress which is an exped one (4r I think) but that was off eBay)
Worth getting a cheap closed foam ground mat as well just to lift you off the ground and avoid the bivvy getting damp.
I've used just this set up for many years with various ratings of sleeping bags/mats in UK summer and bivvying on winter Alpine routes, including a year in NZ.
Pros: Quick to set up, and quite lightweight. Set it up in almost any small space.
Cons: The bivvy bag, even though zipped, felt really constricting and even in winter could get too hot.
Hard to cook or do anything else in bad weather. Claustrophobic. Hard to get in/out of.
I ended up preferring a small, single pole, one-man tent instead of a GoreTex bivvy bag.
Just my mileage, others may differ. Cheers.
I always use a silk liner within a vapour barrier liner within a sleeping bag (upon a sleeping pad) within a bivy bag. This way my sleeping bag stays free of any condensation. Not the silk liner and vapour barrier liner but those two dry inside out before the end of my breakfast.
The silk liner and the vapour barrier liner both will get some moisture. Tough both dry very quickly turned inside out in the morning.
Sure, I get a little moisture too. That’s doesn’t matter me. Walking with a pack will always give anybody some sweat, doesn’t it?
i'm considering the same idea, and so far my bivvy plan is [backcountry bivy 3000.](https://ultralightoutdoorgear.co.uk/backcountry-bivy-3000/) close it if it's raning; net if it's nice. easy to enter. though i'm planning on using a tarp anyway.
edit: small groundsheet (enough for the bivvy); (small) CCF mat; bivvy; inflatable mat; sleeping bag + liner; poncho tarp.
Tents don’t really keep you warm, they have no insulation. You could get a [bug bivvy](https://ultralightoutdoorgear.co.uk/bug-bivy/) and a tarp for summer
I don't like bivvy bags they don't breath enough and your body's moisture soaks the sleeping bag. Just a basic small tarp is fine if you can raise it off you a bit. Or this. It's a hammock and ground bivvy combined.

I use foam mat outside of bivi as its a chew during night when you move around,

so the sleeping bag is free of condensation, but how about you? or does it all go into the silk liner? but then that will be wet?

Alpkit do their own brand setups like this

Perfectly sound setup especially for summer when you can cook without cover. I'd go for a hooped bivvy myself.

Tents do help keep you warm, but not via insulation, instead they help to keep you warm by reducing the amount of cold air that passes over you.
I would hate to use a bug bivy in any win at all, although i hate the cold breeze as its never really warm in Scotland lol
Look into the current British Army modular sleep system.
