I have only used this sleeping bag three times so far but am already very impressed with it. The weight is 1950g and it packs down ok. Preferring to use a slightly larger rucksack and not have to struggle to get my kit into it I don't use compression bags I just put the sleeping bag into the bivvy bag and squash it into the base of the rucksack, this way every available space is used in the base of the rucksack and the sleeping bag never gets too compressed.
The first night I used this sleeping bag I was in a hammock, the temperature dropped to 2 degrees celsius and I was too warm. Though I do sleep fully clothed when in the hammock, I was wearing military DPM trousers and a cotton t-shirt.
The second time was on Pen-Y-Fan in a tent on a very cold, extremely windy night. The temperature was recorded at 1 degree celsius and the maximum wind speed recorded that night was 60mph. I kept the sleeping bag inside the bivvy thankfully because by the time we decided to give up and go back down there was about 1cm of water in the bottom of the tent. The sleeping bag was wet, but I hadn't noticed that it was wet due to the fact that it was still very warm.
On the Solo trip on the Black mountain on the 16th February 2013, the lowest temperature recorded was -2 degrees celsius, I slept totally out in the open without a tent or a tarp covering me. The sleeping bag was in the Hunka bivi bag. I did wake a few times during the night but this was due to lumps and bumps on the ground causing pressure points, not due to me feeling the cold. I could not feel any cold spots and I slept only in my underwear, no technical base layer, just a pair of boxers! In the morning there was a layer of ice on the bivi bag. I still woke feeling warm.
