    Hmm. Spintastic.

    A lower comfort of +5??C does not make a 3season sleeping bag by accepted standards? That's a summer bag.

    I was always under the impression that a 3 season bag had a lower comfort rating a little below freezing?

    I'd have to agree with Mole. I've had a Hyperlamina 20 on the go for the last month (including a fortnight in NW Scotland) and I'd consider that a 3 Season Bag - but it's a fair bit heavier and bulkier. This one? My main question would be: what did they stuff into the pictured bag to make it look as though it's lofting like an arctic rated item?

    I'd agree with Mole too. My Dewline has a comfort rating of around freezing or a bit below, and I think of it as a summer bag, or a weight-weenie-mode "I won't shivertoo much" option if it's a bit cooler.

    I remember camping at Dunkeld (not a high or exposed place) in April and it hit -7 overnight thanks to nothing more exceptional than a clear sky and cold air drainage in to the valley. I was fine in my Lightline, a lot of other people in better bags than this were distinctly chilled.

    Perhaps they mean three seasons in low level parts of North Africa.

    UOG weight it as 564g rather than sub 500g and their view is generous when it calls it a "summer cum 3 season bag"
