0 degree 1lb sleeping bag

0 degree 1lb sleeping. does it exsist? THANX.

0-F or 0-C?? Big difference.

There are plenty of good 1-pound sleeping bags that are good down to 40 or maybe 35 degrees F (which is pretty close to 0-C). Sleeping bag warmth depends on a lot of factors, including what you wear to bed, the humidity, what you had for dinner, etc.

No.

At 1 lbs 2 oz , the WM Summerlite is about the lightest to effectively keep you warm at 0 c , that is 32f.
For 0F you are looking at around 2 lbs 12oz

If you mean 0 degrees Fahrenheit, this will become available shortly after the appearance of dehydrated beer.

A 0 degree(F) bag that weighs less than 1 lb is not currently available.

You could have one custom made, however,...... if you are less than 3 feet tall and weigh less than 50 lbs. I think you might also be able to get a 4 season tent that would be 1 lb or less.

Hey that describes me...
"You could have one custom made, however,...... if you are less than 3 feet tall and weigh less than 50 lbs. I think you might also be able to get a 4 season tent that would be 1 lb or less"

Here I am playing in the snow. I don't have a sleeping bag but I'm looking for one that's easy to get into and short.

Where would I go to get one custom made? Maybe if I had a sleeping bag I would get taken snow camping. I am a side sleeper and us short haired girls don't sleep as warm as hairy boys do. I normally sleep with my head under a towel, so I guess I would need a hood or something to keep my ears warm, I don't have a hat or a balaclava.

Hi, Roxy,

You don't have a balaclava? Have you reported your human companion for animal abuse? A balaclava is one of the most basic requirements for hiking in cool weather...

"O degree 1 lb sleeping bag" is marketing-speak for a 40 degree 1 lb sleeping bag.

I have a 1 lb 4 oz 25F quilt. Accurately rated, as I have indeed used it multiple times into the low 20F range. In fact, I'd guess it may be warmer, as I tend to get cold easy, so perhaps a warm sleeper would get to 20F with it?

I also have a 0 degree underquilt that weighs 21 oz. But you could not use it without a hammock and similarly rated top quilt, so mentioning it was probably unnecessary.

Lori
adding the under and over quilt is 41 oz and I'm sure 41 oz of sleeping bag would be warmer than 2 quilts.

kbennet,
I can't dial a phone, how would I report him?

Roxy--

Tell your human to get in touch with Bigfoot, who can give you a pattern for the sleeping bag he made for Bennie.

He offered the pattern to my Mom, but since I like to stand up and turn around three times before lying back down several times during the night, she doesn't think a sleeping bag would work for me. She calls me her Robert Benchley dog*, and I think she's laughing at me, grrr! Plus, I have a LOT of hair, as several of the humans on this forum are aware!

Best wishes,
Hysson the Hairy

*Footnote from Hysson's mom:

Jim,

I sincerely doubt it. I would need a much heavier/thicker expensive pad to compensate for comfort loss and subsequent loss of sleep due to the lack of the hammock, the weight offset remains...

An underquilt is not the same thing at all as the bottom of a sleeping bag - it's about 1000% more comfortable than a pad/sleeping bag combo could be for me. Get me something that makes sleeping on the ground AS comfortable and warm as the underquilt, and we will be talking apples and apples.

Lori

Jim,

The underquilt replaces the pad. 20 oz. was a good weight for a pad before the NeoAir.

I prefer to use ccf for hammock bottom insulation because I can use it as a sit pad in camp. However, underquilts are more comfortable.

I think we share the amusement of theoretical gear lists that do not include stakes, guylines, suff sacks, straps, etc. needed to actually make it work. My big 4 list is a little over 7 pounds and includes everything and provides comfort on the ground. It is theoretical because I have not yet used the NeoAir in a hammock, but have used a Big Agnes Insulated Air Core. I have had the Black Mamba to 26 degrees and suspect it would go down to 20 with my normal clothes. This list is a pack with a frame and bug netting, etc.

Roxy, please. Sleeping bags are for sissies. I just lay in the snow naked. Take that for a 0 degree (F or C take your pick) bag under 1 lb.

Sometimes you can't trust that snow (especially when it is in Houston):

To address the OP and his question.

Western Mountaineering uses 30 oz of down in their 0F bags. That is just the down, no shell. Nanatuk uses 18 oz of down in their small 5F quilt. Because it is a quilt, it has less area to fill with down, and it still uses more than a pound of down and is not rated to 0F. So, unless you have an insulation that is lighter than down with the same thermal conductivity, then it is impossible to make a 0F bag for less than a pound. Well, unless, like others have pointed out, you are the size of my 5 year old.

You might be able to make one with aerogel, but then it would be stiff, like a board. You wouldn't be able to stuff it in a bag, or even drape it over you. It would be a solid block with a chamber in the middle to lay in.
