My views are that the winter skin does help with condensation and keeping the bivvy drier, the only thing i dont like about them is they make the bivvy darker in the daylight hours.
With regards to winter skins keeping the bivvys warmer then seeing how most bivvys have a door that certainly in my case is nearly always open unless driving rain i cant see it making much difference for any period of time, as others have said its best to rely on warm clothes sleeping bags etc

I'm looking at this warmth debate at night time when sleeping, door closed. But now I think about it, 45% heat is lost through that head. So a good Merino wool hat should help with that. I had issues with condensation with the Chub RS 1 man bivvy (without the wrap) years ago when fishing in the winter months. Trying to eliminate that from happening again whilst keeping warm.
Anyone know anything about the Fox Retreat bivvy?

Mate. Google that thing re 45% heat loss from the head
It isn't how you think. Its kind of been misinterpreted over the decades and then splurged out and copied. It's not anywhere near 45 but more importantly the only ref to original
Science was referring to IF you are wearing thermal clothing
And you leave your head uncovered then what heat escapes
Is X amount from you head. We are not a Swan Vesta

The heat loss through the head is a myth that was debunked some years ago.... Lots of studies since have shown heat loss through the head is proportional to the surface area so around 7-10%...
I've not seen the fox bivvy you mentioned though..

Interested to know more about your bed chair cover and 5 season bag. I have a big snooze+, again, from years gone by like ALL my gear including my bedchair.
I see the value by investing in some quality baselayers. I have some good layers when snowboarding so will likely use them. My jacket and trousers are Pro Logic Jacket and brace. Not designed for maximum warmth however.

Ahh I read Canvas
Hog single nights
Nash Canvas and Hog are awesome and warm. 2 nights
Powerplus Professional 3-4 nights with TV do tend to take a Coleman lantern that helps with drying cloths out etc.
Lanterns Do keep doors open and put outside before jumping into bed.

I find a heat source will help dry the single skin out removing the condensation. I actually have used a lantern for that very reason for 25 years. See below.

I have never used a groundsheet but I have put my unhooking mat under my Bedchair when it's been minus 6 degrees. Makes a bit of a difference.

Groundsheet through winter is better than a door/front on your shelter I'd say. Not sure of any science behind this quote but I'm not one for having a closed up shelter so it may be that.
Plus your swim can get filthy peak winter if the rain is bad

The cold seems to rise up through the floor. Woken many times with a cold back in the past. That's when a quality bag comes into its own. I used to have a foam topper on my bed for comfort and insulation reasons. Now have an inflatable mat. Interesting about the unhooking mat under the bed as the post below
When it's proper cold I have felt the cold coming up the inside of my bag cover
Condensation iced up inside the tent with a wet patch above my head when using single skins

This is with the doors open i take it?

Door would be down however their is some gap to allow for air exchange so not a closed system.
Thermal energy flows from warm to cold, everything is a heat sink,
ground sheets act as an insulator so too thermarests (inflatable matts) used my unhooking matt placed on the ground under my bed to reduce heat loss as a kid.
Additional skins such as a canvas helps loads and a UCO tea light helps reduce condensation.
Mid winter freeze ups and waking up in the morning and watching the condensation defrost and start to drip over the bed chair. Cup of tea happy days

Just do what you are personally happy with.
I've fished all year round, every year since the mid70's so over that time I've used all sorts of shelters as the tech improved over the years. Nylon brollies with shower curtain sides, black bin bag over the end of the army feather sleeping bag, Nubrollie style brollies which condensate instantly the temp drops, nylon bivvies, Aquatex Bivvies, Overwraps etc.
Probably the warmest ones were the Nash canvas brolly wrap and the original Aqua Dome with the thick cotton/canvass inner. Both came with their own problems though.
I'm now in my mid 60's so for me in winter it's a bivvy and overwrap combo in winter but the door open, decent clothing (non fishing brands) good bag, thermal blanket etc. The days of waking up covered in frost are now well behind me.
An old army saying = “any idiot can be uncomfortable” still rings true.
Also If something makes you feel happier and content on the bank it is worth doing, regardless of whether the science behind it is totally sound. It's a bit like having a tot of something in your coffee. The science says alcohol lowers your body temp, but it does give you a feel good factor in a hot drink. On a cold,dark night on an inhospitable lake, if you can't say “this is the life” whilst eagerly anticipating a run then you aren't doing it right 👍

Echo that mate
I used the tea lights for quite a few years. I gave up with them after I thought they were damaging the roof of my Bivvys, always seemed to leak above where it had the tea lights, strange considering it is burning wax vapour, would think it would have a reverse effect.
