Low cost 20-35F bags?

PHD a high end English made down gear manufacturer is going to have their once a year sale. Their light weight down bags will be between 40 and 60 percent off. When you order from the UK you can subtract 17.5% VAT (taxes) and shipping is usually $15 to $20.

I bought a non-woven poly blanket for $5 and it worked to 45 degrees. Haven’t had the chance to take it out in colder weather yet. I added small snaps.

Less bulk than my regular syn bag and weighed 1.5 lbs.

What is the URL for a site that sells the blanket you are referring to?

Approximately how thick is it, what are the dimensions, and how much does it weigh?

bedding section
1/8″
I cut it down to 80 X 72
I’m 6’2″ & 185#. I toss and turn alot so I would wrap the blanket loose or tight as needed.

I will do another at 80X 40 for more overlap

I wonder what a Vellux blanket weighs. They are the light, short pile blanket you find in a lot of hotels. It would be pretty easy to turn one into a sleeping bag. $20 for a twin at Chez K.

Interesting suggestion. I guess you could add it to your cape/ tarp as a liner when not sleeping. Just imagine that, a Martha Stewart product keeping you all warm and fuzzy in the wilderness!

I’ve been looking for more information on aerogel blankets and honeycomb milk bottle blankets but haven’ been able to find any information for buying any of these things. Seems like they would be ideal.

AEROGEL BLANKETS??????? That is crazy talk. IIRC Aerogel is niether durable, nor shock resistant, nor flexible, nor fibrous, nor compressible and to top it all off water makes it disentigrate.

The link to the plastic honeycomb fiber insulation is neat though!!!

I purchased a used Montbell UL SS DH #3 from Carol Corbridge. I cannot wait to use it. I am so stoked! It cuts about 2.5lbs off my sleep system as I’d been using my 63oz SD 15F long down bag for the 30-50F range.

I hope that will give the curious some food for thought. (^J^)/”

People thought (and many still do) that Ray Jardine’s ideas were crazy, but look what happened…

Wow! I stand corrected! Thank you for the links! Perhaps it is usable afterall!…

PacOut is looking to use it in their InsulMats! w00t!

Through 1/oz 1/8″ layer on the bottom of any pad and add 8 to the R value (talking out of my rear) that would be SICK!

Compressibility, and for clothing, breathability, look like issues. It seems very cost prohitibive right now…

“In the future a -40F bag will weigh the same as a 32F bag because the shell/zipper is the weight, not the insulation. And they will be light!!!!” – My prediction

Ive contacted Aspen Aerogel on a number of occasions trying to buy some blankets for making gear with – – after trying for literally weeks to get them to return a phone call, I got a hold of someone and she outright refused to sell anything to me. She wouldnt even give a price.

Too bad too.

Compressibility isnt really an issue, so far as I can see, because the insulation would be so thin that it wouldnt really NEED to be compressed. Your mountaneering coat could be as thin as a 200wt fleece sweatshirt.

Check this one out – a bit past your price range and weight range, but also exceeds your temp requirements.

You might check out the Phantom 32—21 oz. at a reasonable price.

I have been looking at this bag and am researching a couple of questions.. I am 6’3″ and this bag max’s out at 6’4″..concerned about is it long enough. Secondly, the #3 bag is rated to 32 degrees …I know there are lot of variables affecting comfort and warmness but, inside a tent with reasonably warm clothing could one expect to be warm at say 25 Degrees? Or, do you just go to the #2 bag which is rated at 20 Degrees?

Im 5’9″ and the regular sized montbell that I use “tops out” at 5’10”.

I fit fine in it.

I can even tuck up the last baffle and use it like a foot pillow if I want.

I dont see why there would be a difference for the longer lengthed montbell.

Jim: If it is any help I am 155lbs 5’9.5″ and the regular #3 fits me perfectly although there might not be room for that platypus full of hot water at the bottom. As to comfort, varies from person to person.

THIS
BAG
IS
SO
COMFY!

I’ve never had a bag so light and yet every bit as comfortable as a SD Van Winkle 15deg 4lbs bag.

I am now wondering at making it a winter bag by buying a Big Agnes 15 or 20 bag as an overbag or just buying a BA overbag.
