Hi all,
Just been reading through this list of posts, and the last test seemed really good. I think it was a little unfair though to pull the bally down over you face in one liner and not the other. As we lose over 20% of our body heat through our head (not just where we have hair, or not if your bald like me) the test would only be fair if everything was exactly the same bar the differing liners.
But I always sleep as near to naked as posssible, and as long as I'm hydrated, and my bag is dry I never have a problem in temps down to -5 in a -5 rated caravan(made by ajungilak) bag. I just throw all my clothes in the bags with me and in the morning I always appreciate getting out of the bag and getting dressed. If you wear your clothes in there, its like standing in the cold all night well wrapped up, then taking your coat, hat, gloves off first thing in the morning.
My 2p worth and MVHO
Hello Hawsome34,
Thank you for your comments, which are very welcome.
Im not pretending that any of the tests were scientific in any way, but hoped that they would be a little more revealing than a Ive got one and theyre great type post, which tells one pretty much nothing about any given product (This comment isnt intended to insult those who do this, I do it myself sometimes when Im pressed for time).
The swap from the Thermalon to the cotton liner was an impromptu thing that I did out of curiosity, and was as you say unfair in some respects. And the only reason I pulled the balaclava over my face was to warm my cold nose
(Which may have been caused by the slight drop in temperature to below freezing while I was asleep).
There are so many variables involved with sleeping bags (And clothing) that it makes it very difficult to say that one bag is better than another, not to mention all the variables to be found among human bodies with differing rates of heat production and so forth. This is why I gave an indication of the amount of body heat I radiate (I cant measure that, as I dont have the scientific knowledge or equipment to measure such things), but I would describe myself as neither a hot sleeper or a cold sleeper, which would make me perhaps average and therefore a useful guide (The use of the word average may also be contentious).
I thought that as I dont run particularly hot this might have been of use for any women reading, as Im informed that a womans body temperature can be somewhat lower than mens (And a man in his twenties runs the hottest of all, according to a Mammut document I read).
I could have answered Bjorns question with a simple Yes, which would have answered all that he apparently was interested in. But what would anybody have learned from that? I chose to interpret his question as Has anyone used an Endurance -10º at -10º? The answer to that question, if that was the question being asked, in my case, would have been No. So I tried to provide an answer where one could make a reasonably fair extrapolation - If one can sleep comfortably in a 0º Nanok bag at 0º this is an indicator that Nanok have temperature ratings that are realistic and reliable (Even with a larger internal volume to heat), therefore, sleeping in a -10º Nanok bag at -10º is
probably an equally comfortable experience.
Of course the total lack of feedback from Bjorn wasnt helping any (This may be for good reasons, he might for instance, be in the Arctic Circle, and away from the computer
ah, I note, having just logged-in and refreshed the page, that Bjorn is back
).
I take your point, Hawsome, about getting out of the bag and
then taking your coat, hat, gloves off first thing in the morning
I found however that after putting on denim jeans and footwear, that the plunge in body temperature didnt take place. The Nanok Air Jacket isnt meant to be an outer garment anyway, and is somewhat akin to a quality fleece. If one were feeling the chill after emerging from the comfort of the bag, putting on an outer layer is always an option.
And if you can sleep in comfort in a bag outdoors at -5º and in brief underwear, then my guess is that you are a hot sleeper and/or I need to urgently explore the Ajungilak bags!
Anyway, many thanks for your interesting comments.
Best regards,
Paul.
