according to the local weather station it was 10'C "feels like 7'C" - amen to that, it certainly did. The wind was tunnelling through.
I setup in the light and did my best to get the underblanket setup correctly. This is my third underblanket. The first was 3/4 and just wasn't long enough to usefully work in winter conditions. I can't stand cold shoulders or cold feet! The 2nd is UKHammocks (Matt) home made one - but it doesn't have as many securing tabs, so I thought for the money I'd try the DD one!
There's no instructions in the pack, so it was somewhat guesswork. I got the wife to sit in it and I ran my hands under to make sure it was just sprung under and not too tight against the body. When I got in, it was very toasty. Initially after I settled I had problems with my feet -the top blanket felt breezy. So eventually I checked and found the pull chord. It felt better, but after a while my feet cramped (I'm 6ft 4ish, so at the limits of the equipment). I got warm and my feet were definitely warming up. I'm not sold on the open foot end at the moment.
I definitely dropped off though it was a broken hours sleep as we're close to an airport, there was a lot of noise so I stuck in my earplugs. I'm pretty sure at one point I woke up myself up with a snore. At about 11pm I got woken a 2nd time by a loud BANG in the garden. Think a cat may have misjudged a leap onto the BBQ! At this point I realised I was freezing cold and the nice warmth from the underblanket was gone. I checked it, but it all seemed fine. I suspect it may not have been quite tight enough against my body and perhaps a small draught was running underneath.
I got up with the intention of grabbing a sleeping bag and making my way back, but having traipsed inside, I decided to knock it on the head and try again another time. It's still up, perhaps I'll try again tonight after further adjustments.
