Quilt

I too am looking for a sleeping bag, Preferably not over £100(or not too much over) for -12 degrees Celsius, as small as possible, and no bright colours

>cocoon silk mummy wrap that supposedly adds ~5f to warmth
9-10F

What do you mean 9-10? It adds that much?

Take whatever lowest temps you expect to camp in, and then subtract 10 degrees. That's the quilt you need.

Example, if you expect 10 degree temps, get the 0 quilt.

That gives you a little buffer in case the temps drip unexpectedly. Quilts are much easier to vent if you're a little too warm, so I wouldn't worry about being too warm. Id use the liner just to add a few degrees if you're expecting really cold temps.

Does anyone know of a site that lists average alpine temperatures?

I know... it is hard to pick for me because often the temperatures can change dramatically... not to mention the mountain tops i believe average 1C to -8C

You can do the rule of thumb, subtract 3.5 deg F for each thousand feet of elevation. In reality forecasting in mountainous terrain is incredibly hard because of the topography. Best weather site I've used is spotwx with the HRRR NAM RAP models which are all non hydrostatic. People bring up mountain-forecast.com, but in my experience their forecasts are completely divorced from reality and science.

For your budget down is downright out. But they are the lightest, so if you change your mind, check into East European down bags. You can find llight and good quality and they can accommodate custom choices at the factory. Not for 100 quid though.

Synthetic is generally cheaper so if you are hard set on 100 £ then you look for synthetic filling with your chosen comfort temp, it is a rather straightforward calculation as there won't be many choices.

Don't diss the bright colors, unless it is a real mission requirement vs. aesthetic preference. If you get into trouble it can save your ass.

It's hard to say as only you know how you feel the cold.

Other than that, I have their 30F Enigma quilt and love it. Super bit of kit.

Well OP here. I opted for the 0 degree, easier to take layers away than struggle for warmth. The waiting game begins

Is that generally true? About 2° C for 1000 ft?

Generally, yeah, it's called the lapse rate. But there are huge variations around the world and dependent on weather, so it's a very rough guideline.

if you're cheap enough just carry garbage bags, sleep inside a garbage bag inside a shitty sleeping bag.
garbage bags are easily one of the best insulators you can wear for your money

Ive always thought about that... but i always think that i will end up buried in the woods in my own bags
