Being as the bag is synthetic and the water was relatively clean your likely ok to boil wash it and use it again. If it had been down and/or contaminated water I'd strongly recommend binning it. Down would have rotted and you couldn't guarantee getting rid of all of the nasties in contaminated water. Caveat(s) It's not going to be like brand new. The ...

You shouldn't leave your sleeping bag compressed any longer than you need to. Store it out of it's bag on a shelf, hanging up, or in a large breathable storage bag. Only stuff it into it's stuff sack or a compression bag when you're packing it. If you store it compressed it will lose loft, which is what gives you insulation. How quickly it loses loft varies ...

It's a novel idea, but it's not going to work in any practical sense. Most of those foams take about 15 minutes to setup, and you'll have to come up with some way to fabricate a mold while you spray it. It will be about an hour before you could safely enter your foam sarcophagus, and if this is to be used in an emergency situation, that's probably not time ...

No, it's not going to be feasible: You'd need a lot of cans. To approximate the volume of a sleeping bag and thermal mat I'd say at least around 5-10 cans. For this weight/volume you can just as well bring a proper sleeping bag/tarp/bivvy. The spray foam is not stable in itself. It will form bubbly clouds of foam, so you'd need a mold. This is not easy, ...

Depending on where you are camping I would recommend a three or four season synthetic sleeping bag. Synthetic bags are generally cheaper and bulkier than down bags for an equivalent warmth. As you are car camping the additional bulk isn't that important. Most of Spain has night temperatures between 5-0 C this time of year so a three season bag should be ...

Aside from layering your clothes inside your bag, or layering your bag using a bag liner, it's also important to make sure you have a good ground sheet or sleeping pad that will insulate you against the ground and reflect your body heat back up. You lose a lot of body heat into the ground while sleeping, so at the very least, using a survival blanket as a ...

You covered it already—layers. This is actually a very common technique among ultralight backpackers. They will often intentionally bring a sleeping bag with 5-10ºF less insulation than needed and compensate by wearing all their clothing to bed. If you need to get warm fast, you can do some sit-ups to get your blood moving. You only need to worry about ...

It's hard to give specific advice on exactly what sleeping bag you should buy. What I can help with is some general advice on what to look for: Filling Probably the most important thing. Generally two types of filling will be offered: Down (see types of down) Synthetic Synthetic is typically much cheaper than down. But it's also bulkier, heavier and ...

There was an old Reader's Digest story, apparently true, where a camper woke up with a very big rattler (as he saw later) coiled on his chest under the sleeping bag. He had trouble communicating to his friends what was happening and the things they tried (I can't remember what, maybe messing with the zipper) just seemed to agitate the snake. They ended up ...

Using a sleeping bag liner can usually add 5-8°c or more warmth capability to your sleeping bag. However, do not use a cotton liner if you are in cold climates, as that can hold onto moisture from your body and cause you trouble.

Several good tips have already been posted; another to consider is a hot water bottle. I was on a trip for a mountaineering class recently and was surprised by how many people had never slept with a hot water bottle before! Use a solid bottle which won't leak and is designed to handle high temperatures, like a Nalgene bottle. If you're already carrying fuel ...

It is possible to clean/repair your bag if it's not too far gone, but buying a new one will be easier, might even be cheaper, and will certainly be better. Options for cleaning slightly mildewy bags include using vinegar or bleach (bleach will likely discolour the bag) and hot water in the wash cycle. If washing the bag and tumble drying doesn't get rid ...

I've used a cotton bag liner for winter camping for the past couple years, I love it. I'm usually a huge opponent to wearing cotton in winter, but that's because most people are pretty careless about moisture control these days. If you read my answer to, "Does Cotton Really Kill?", I point out that cotton was worn on the very first summit of Everest. The ...

This question is almost as hard to answer as the question about a good knife. :) A general rule: The more expensive the sleepingbag, the more expensive the materials involved, the better the ratio between packweight, packsize and temperature. However this totally ignores the additional costs for the brandname and such. One company I can really recommend ...

In my experience the two most important things you can do to improve the range of a bag are: Improve your ground insulation. Warm your extremities. Ground insulation is far more important than most people appreciate. If budget is no object you can invest in the NeoAir Xtherm, which is a breakthrough product. On a tight budget you can buy closed cell foam ...

The impact of compression on loft can come from how long a bag is left compressed, or from the number of times it has been compressed. As the main risk with compression is the breaking of fibers that would otherwise contribute to increased loft, many repeated cycles are more likely to cause trouble. That said, synthetics and down are different. Synthetic ...

Have you tried tossing it in a dryer on Air Fluff with some tennis balls, for a little while? Edit: See also suggestions here.

I'm not sure that anyone can give you a specific number that will suit your needs. Its worth bearing in mind that the temperature ratings on sleeping bags are created using a somewhat arbitrary test involving a dummy with sensors read more. The good thing about this test is that it creates an objective position from which to judge a sleeping bags insulation ...
