My mate has a full roll; or what’s left of it; of the gold foil backed flooring underlay.
4mm thick PE film; PE foam and the reflective foil on top
Similar to what we use up the hills in winter here.
I got my end roll from a skip at a building site, cost me a can of cold coke; there was 11 metres left on it
If I need extra I’ll grab some from his stash and tape it to the floor semi-permanently
If I use a pulk the tent goes on top rolled out flat to put up fast if need beAug 22, 2017 at 12:09 am #3486425

In my personal experience, at sub -35c temperatures after 3 or so days there starts to be a lot of moisture in the bag, and the warmth drops off. I haven’t tried layering bags, but I expect it could work well. I would double
So your trip is 90 days total, and each “leg” or the longest time between resupplies / some place to warm up would be 12 days? If so I would get a vapor barrier sack. They are (or can be) very unpleasant to sleep in, but if I was looking at more than say 3 days of nights of sub -35c weather I would be using one.
I would also error on the side of caution – 55c is really, really cold. The coldest I have experienced is -51c, and at those temps a lot of things no longer function all that well. Fabrics get stiff, plastic brittle, etc.
If I may ask – where and when are you going? Spring time? That can make a big difference – where I live (interior Alaska) we get lots of solar warming during the spring, but still have very cold nights. In the main part of winter we get cold days and nights with almost no warming during the day :)
Have a great trip!Aug 22, 2017 at 4:22 am #3486430
To be honest Jay I have no idea where I’m going
it is a bucket list trip and I’m spending my childrens inheritance to do it, I’m not getting any younger fast and all of my contacts seem to be in the same age and decrepitude bracketSep 6, 2017 at 8:57 pm #3489530
Did you get your sleeping bag yet?
In customizing my WM Puma -25F/-32C, I opted for the foot box overfill plus the Gore Windstopper. The thinking behind Gore Windstopper is (1) in case a shelter should fail and I would need extra protection, and (2) it may retain heat a bit more than microfiber. The drawback of GWS is that it’s stiffer than microfiber and is more annoying to stuff into a pack. It costs a bit more, too.
The WM rep said that most customers choose microfiber over Gore Windstopper. The WM Ponderosa 15F/-9C is only in microfiber and that fabric feels luxurious. If I got another WM bag, I would easily go with microfiber.
Feathered Friends uses Pertex Shield for their sleeping bag shells. Their goose down insulation is from the same source in Poland as Western Mountaineering but FF uses 900+ fill vs WM’s 850+ fill.
One more thing, my Puma is still too cold in 15F weather unless I use disposable hand warmers because I don’t generate enough heat on my own.
A camping buddy of mine uses an Uco candle within his tent for both minor warmth and to handle any would-be condensation. I haven’t tried it yet.Sep 6, 2017 at 9:55 pm #3489549
Not yet, during this winter here I have tried a few and as a side sleeper I have found most new / modern iterations of the winter sleeping bag have the zipper in the wrong place [ my current winter bag has no zip at all]
I am saving my pennies to have Nunatak sew me an Extra Large Arc Alpinist 20F, where the zipper is in the right place for comfort and ease of use
The combination of the Alpinist plus a down jumper and a half bag plus the overquilt should be all I’d ever need and if not there’s rumSep 11, 2017 at 10:52 pm #3490490
Where is the right place for a zipper if you are a side sleeper? I sleep on both my right and left sides.Sep 11, 2017 at 11:03 pm #3490494
Centrally, which is where most zippers were for many years. Most of the winter bags i have owned over the decades have been zipperless but I did own one from Egge that was a central zip and that was magicSep 11, 2017 at 11:19 pm #3490496
Centre, no question. Hood then on top of your head.
And that lets you turn it into a good quilt too.

Center zipper on bag much better. You can unzip and push bag to each side when it’s warm.
Side zipper – you bush bag to one side and it gets into the dirt, and on the other side the dirt gets blown inside your bag.
I didn’t know that anyone makes bags with center zipsSep 12, 2017 at 7:39 am #3490524
Almost all military bags in Europe have gone back to the short centre zipper, GoLites original bags that got such rave reviews were centre zip but in down so far I’ve only found them from Nunatak and TNF
In synthetic tho there is a better selection from TNFSep 12, 2017 at 11:42 pm #3490724
I got swept up with WM bags and completely overlooked TNF center zip bags. Nunatak is new to me and look forward to your review.
However, in putting together a hammock setup for my son, I got an Eddie Bauer Flying Squirrel 40F bag (US $299 retail; $122 Amazon; $100 eBay), I thought the center-opening of the wings would be easier to get in and out of a hammock. I liked it so much, I bought a second one for myself. It has
In warmer weather in a tent, I use this as a blanket. My feet never seems to stay in the foot end because I mostly sleep on my side curled in a fetal position and occasionally like DaVinci’s Vitruvian Man. I really enjoy this design and am pondering a MYOG winter version with thicker loft, collar and draft tubes a la WM.Sep 18, 2017 at 8:42 pm #3491810
Interesting design, it also looks like it would make a good liner bagSep 18, 2017 at 9:18 pm #3491819
I would not use it as a liner BAG, but I can see that it might make a rather good sort off quilt to go under an over-quilt in the winter.
Sue and I favour our 600 g summer (MYOG) quilts, which we can double over the two of us if it suddenly turns cold, but we also have a larger double over-quilt (also MYOG) which has worked very well in the snow over the two of us. Using an over-quilt has not only kept the two of us quite warm in way-sub-freezing conditions, but also means that our summer bags stay very dry. Any condensation which occurs is in the over-quilt, which we manage to dry off fairly easily.

I’d love to see your MYOG quilts. Could you post pics or a link to pics?
We took the flying squirrels camping in 65F nights with a Hilleberg Jannu with the inner tent’s mesh revealed and it was perfect. I read some reviewers used the flying squirrel within other sleeping bags or under other quilts to add warmth. I haven’t tried the bag-within-a-bag combo yet. Maybe the flying squirrel will make my FF Swallow 20F bearable for me in 15-20F nights.Sep 20, 2017 at 10:58 pm #3492199
