My BOB

[Scythe13]

I use an ultra slim sleeping bag, but layer it up. I have a thermal layer inside the bag, and a microfibre layer inside that. If need be, I have a waterproof layer I can wrap the whole thing up in. With that, I use a self inflating mat. Works for 3 seasons very well.

This winter, I hope to get another thermal layer and a second mat (just to experiment with) and will see how that holds up over. My prediction, it'll be okay for a max of minus 5, or there about.

Oh, and I have a mylar (space blanket) sleeping bag bag, if all else fails, but that makes me too hot and sweaty...which can backfire pretty easily in the cold, so layering is vital to wick the sweat from the outside of your body.
