As I was early up this morning, I decided to test the new Rab bivy bag, and also to see how quick I could set it up.
I was a perfect morning for it; about 3ºC and a bit of morning damp.
Set up was fairly easy, as in about 2 minutes I had the kit layed out. I used a simple nylon bivy bag as a ground sheet, on which I putted the Thermarest Pro Lite 4. As a sleeping bag I used the Decathlon Ultralite SQ down bag.
In the beginning my feet (no socks) where a bit cold, but in no time I felt very comfortable, and slept well for about an hour, as the the noise of the dustcollectors truck woke me up and reminded me to put the dustbin at the street for pick up.
Checking my sleeping bag showed no moisture or condensation, it was quite dry, only the inside of the bivy bag had some moisture just around the opening.
