Talk:Sleeping bag

Sleeping bag with arms and legs

There was a section under 'types' that listed "sleeping bag with arms and legs" as a variation of sleeping bag, along with a picture (that had the brand name in the corner. Looked like spam to me. Post here if you disagree.

I see that the arms+legs picture has been reposted without a visible brand name; fair enough. Could the editor who added that picture please supply more information or some useful references please. I'm inclined to think that it would be heavier and/or more bulky than a rectangular or mummy bag, and (due to greater surface area) would also be less warm, so I'd like to find out a bit more.

We should really get some secondary sources that refer to this form of sleeping bag. I know that various innovations in sleeping bag design have come and gone, and this seems like another minor blip. I'm not aware of any retailer selling a sleeping bag like this. Unless this is a significant product we should probably leave it out.   Will Beback  talk  18:37, 23 November 2009 (UTC)

I've found a UK web site selling this bag http://www.lippiselkbag.co.uk/. A ggogle search for "arms+legs sleeping bag" throws up a few secondary retailers as well. I agree with Will Beback that some secondary sources are desirable. Murray Langton (talk) 14:06, 24 November 2009 (UTC)

This is clearly spam, the MusucBag site seems to be using Wikipedia as a marketing tool: http://www.musucbag.com/about.html. All the current examples of 'sleeping bag with arms and legs' appear to be the same product from the same manufacturer. For now, this should be removed IMO. I've found absolutely no compelling evidence that this is a popular form of bag. 87.194.207.189 (talk) 19:22, 25 November 2010 (UTC)

Further proof: The image that has been linked to (File:Sleeping_bag_with_arms_and_legs.jpg) is clearly a marketing/catalogue shot for this product. Since it has been uploaded (and released under cc-by-sa-3.0) by the copyright holder, this is clearly spam by someone attempting to market this product. 87.194.207.189 (talk) 13:54, 27 November 2010 (UTC)

Content removed - please only re-add this if you have credible sources to back up the claims that this is a common (i.e. noteworthy) 'third type' of sleeping bag. 87.194.207.189 (talk) 13:54, 27 November 2010 (UTC)

My idea was why ith dont sleeping bags lock? Where's the lock mechanism to the zipper? Real though guys, come on...comon. — Preceding unsigned comment added by 69.255.42.105 (talk) 12:48, 15 September 2011 (UTC)

Why is a lock mechanism needed for the zipper? SOme sleeping bags have a velcro fastener which covers the top of the zip. Murray Langton (talk) 20:12, 15 September 2011 (UTC)

Extreme is for a woman?

Is this gender equality, or do women have different heat requirements while sleeping? —Preceding unsigned comment added by 67.70.153.164 (talk) 04:50, 7 September 2008 (UTC)

It's not sexism or gender inequality - women do require more insulation than men to an extent. It's related to metabolism and size (mass to surface area ratios etc) and other considerations. Think of it as akin to men needing more calories than women Audigex (talk) 19:35, 8 March 2011 (UTC)

Three sides?!

"A basic sleeping bag is simply a square blanket, fitted with a zipper on three sides" - Shouldn't that be two sides?Anonymous55 04:35, 16 December 2006 (UTC)

Good catch. -Will Beback · † · 05:22, 16 December 2006 (UTC)

Ever unzipped a sleeping bag? It's 3 sides - the left attaches to the right, and the two halves of the bottom attach to each other. Otherwise you'd just have a tube Audigex (talk) 12:43, 17 February 2010 (UTC)

Edit further to this - I've changed the article since when the sleeping bag is zipped up the zip is one two sides, but when it is open the zip is on three of the sides. The sentence in the article talks about a blanket with zips on the sides, so it's discussing the open state. "One to three" sides could be accurate also? Audigex (talk) 19:33, 8 March 2011 (UTC)

Origin

Does anyone know who made the first sleeping bag? 220.253.9.235 14:05, 13 January 2007 (UTC)

The idea is so obvious that it's probably very old. But legend has it that the wicked Viking woman Freydís was the inventor of the sleeping bag.[1]--87.162.45.172 (talk) 21:04, 19 March 2008 (UTC)

Weight ratings

Sleeping bags are often rated in terms of grams per square metre (gsm), which i presume is the areal density of the fill. It would be nice if we could discuss this a little, and indicate what weights are suitable for what conditions. This chap:

http://au.answers.yahoo.com/question/index?qid=20080405132839AARJqTG

Says that 125 gsm is good down to 5 degrees C, which is cool UK summer night temperature, and that a 350 gsm bag is suitable for four-season use in the UK. I honestly can't find any more info than this by googling!

One thing i notice is that the tog rating of a bag isn't perfectly correlated with its weight. Taking numbers from that unassailably authoritative source, the Argos website, some examples:

Weight (gsm)	Thermal resistance (tog)
200	4
200	6
250	5.3
300	4
300	8
400	9

I suppose things like shape, stitching, whether the zip is baffled, etc can make a difference.

The fill weight doesn't have much to do with the temp rating. You could have a 900 fill 50 degree bag, and a 200 fill -30 degree bag. (Although the 200 fill -30 bag would be freaking huge). the fill weight just says that for a given amount of temperature control, higher fill weight will have less weight and size overall. (gsm and fill weight are both talking about density of the insulation, sorry for switching units in my answer though) Gaijin42 (talk) 15:31, 4 March 2013 (UTC)

"Extreme" section needs clarification

"the extreme rating is a survival only rating for a 'standard' adult man. This is an extreme survival rating only and it is not advisable to rely on this rating for general use."

What does "survival-only rating" mean? — Preceding unsigned comment added by 69.116.73.64 (talk) 02:41, 4 March 2013 (UTC)

It means the bag is rated to keep you alive at that temperature, but that you probably won't be happy about it for comfort. Gaijin42 (talk) 15:29, 4 March 2013 (UTC)

Gro Bag

Why does gro bag redirect here rather than to the Growbag page? Gro Bag is a registered trade mark for a brand of compost package designed for growing plants in, not a sleeping bag. MidlandLinda (talk) 11:53, 8 May 2017 (UTC)
