Not that cold but it was a very clear sky and PW camping near me was saying he was freezing in the night with a fleece etc on in his tent. I just had a T-shirt on and I normally feel the cold.
I`ve put my money where my mouth is & bought a new bag, a Snugpak Softie elite 3 Its got an elasticated zip baffle attached that can be zipped in to closed the bag up tighter or zipped out to make the bag wider for a bit more elbow room. Comfy at -5 or so it says
I spoke to Les at TravelDri Plus this week and he said that they only have a few Nanok sleeping bags available. The UK importer no longer brings them over, so he is looking for a suitable replacement.
So if you want a Nanok sleeping bag, get in there soon. They are very good bags
