MT900 50°F/10°C

I have Decathlon’s down sleeping bag, which is quite a mummy bag. I had the same concerns as you, as I tend to roll around a lot and sleep in different positions. I’m finding I really like the bag. If I roll around I tend just to roll with the bag. It doesn’t bother me at all how tapered it is.

I'm from Europe too, I usually look for Decathlon or Naturehike, those two I've tested them and they respect the temperature written, at least in Italy decathlon is the best price/quality ratio

It depends, mainly Forclaz,
