It's a baker tent[1] made from SOL Emergency Blankets[2]. They get warm, but what doesn't when you have a long fire in front of you. [1] http://ruralsportsman.com/rediscover-the-baker-tent/ [2] https://www.surviveoutdoorslonger.com/survive-outdoors-longe...
>They get warm, but what doesn't when you have a long fire in front of you.
The shitty fireplace in my piss poor excuse of an 80s designed house. It's almost as if it was included as a check mark in a real estate listing rather than how to make it useful.
Those emergency blankets don’t work like normal blankets - by trapping air and preventing it from moving - but by reflecting heat and keeping it in.
And they are not comfortable, as this post shows: https://www.reddit.com/r/CampingandHiking/comments/4wtetp/im...
But if it is an emergency, and that's all you've got, it's a lot more comfortable than not having one. It's almost like they are purpose designed by looking at the name of the product.
Thoreau says this, in The Maine Woods [0]. (EDIT: Thoreau says that he lived in a tent in Maine, not at Walden Pond.) The author of TFA got it a little wrong. Note to those wanting to replicate this: I'm pretty sure Thoreau's tent catches fire at some point. I'd have to re-read to confirm or deny if it had anything to do with setting the tent in front of the fire, as the author of TFA does. [0] https://www.thoreau-on…
“A shed-shaped tent will catch and reflect the heat like a Yankee-baker, and you may be drying while you are sleeping.” Page 124: http://www.thoreau-online.org/the-maine-woods-page124.html “ We had no sooner pitched our tent than the thunder-shower burst on us, and we hastily crept under it, drawing our bags after us, curious to see how much of a shelter our thin cotton roof was going to be in this excursion. Though…
Thanks for looking. It is entirely possible that my middle-aged memory on books read 25 years ago is...not entirely reliable. :-)
I've been sleeping in Hilleberg tents for probably close to a year of my life. They are very robust at a great (though not ultra-light) weight. I own a Jannu and a Keron 3 GT.
Hilleberg tents do seem nice in terms of the fabrics they use and the design. However, as the long-haul cyclist community has found, the zippers give out appallingly early for such an expensive, artisanal product. (By the end of the Carretera Austral there seemed to be more Hilleberg owners with broken zippers than with working zippers.) I owned a Hilleberg Nallo GT-class tent that did seem like the five-star hotel o…
The zipper is a great invention, but it has yet to be perfected.
I'm not a physicist but wouldn't this reflective effect be tiny compared to the prevention of convective heat loss?
Considering average human body area is around 2 square meters and body temperature is around 37 degrees Celsius I get around 1000 W of radiation from the human body according to this calculator: http://hyperphysics.phy-astr.gsu.edu/hbase/quantum/radfrac.h...
Human skin temperature is considerably lower. (Or to think of it from another perspective, the system which is insulating your core temperature includes layers inside your body – skin, etc. – in addition to clothing, blanket, etc.)
Fabrics are a really underappreciated aspect of a lot of modern outdoor gear, especially with respect to weight. My main objection, as I mentioned in another comment, is that durability is one of the tradeoffs. A few years ago I had one of the super light and compact sleeping pads develop a leak after literally about three days. It was replaced for free but that didn't help at the time. I have a new very lightweight…
> I had one of the super light and compact sleeping pads develop a leak after literally about three days. Therm-a-Rests are a dependable brand in this regard, as while a leak may happen from time to time (I have had two punctures in about one year of sleeping outdoors), it is usually very easy to find the hole and patch it yourself, just like you do with a bicycle inner tube. I think Therm-a-Rest even includes the pa…
This was Synmat. Should probably have had a repair kit with me but as I recall there were multiple leaks. And have several older Thermarest products. But there are definitely tradeoffs between weight and durability.
> Those emergency blankets don’t work like normal blankets - by trapping air and preventing it from moving - but by reflecting heat and keeping it in. This reads as if to imply emergency blankets vent air freely, that's obviously not true.
Thermal insulation, whether we're talking about a blanket, a winter jacket, or the foam stuff in your walls, generally involves a layer of some thickness within which there are many tiny spaces full of trapped air. It's difficult for heat to propagate across those spaces. The author's point is that mylar emergency blankets do not provide this thick layer of "trapped air". It's true that they prevent air from crossing…
Heat is transmitted by radiation, by conduction and by convection. A foam jacket blocks heat transmission by preventing convection. A mylar blanket prevents transmission by radiation and convection. Yes, it still loses heat to transmission but it isolates rather well. Unsurprisingly, that’s why they are used as emergency blankets.

HUUUUGE fan of Hilleberg. I have a Nammatj I've had for nearly 8 years and it's going strong. And I've taken it to the Andes, the Himalaya, and even deserts.
I'm guessing it's a Zpacks Duplex, it's basically the favorite tent of any through-hiker for the last couple years: https://zpacks.com/products/duplex-tent They are very well designed and built--100% DCF so they're strong and light, yet great resistance to weather. Unlike most other UL shelters it makes almost no sacrifices and has all the niceties of heavier shelters, like a full floor and interior mesh, big vestibu…
I love my Duplex as well, and that was also my guess. I would note that the biggest downside (other than cost) is that the Duplex is not a free-standing tent (although they do offer a couple of free-standing versions which are significantly heavier). It will sometimes require patience and creativity to set up the tent in areas that are very short on usable ground space (like dense forests or steep terrain) or hostile…
It's definitely harder to setup with 8 stakes, and you must carry poles, or borrow a friend's poles, but it's incredible how much lighter it is over almost any other option.
