This is the award winning KSB 20 Duck Down sleeping bag from Klymit.
It’s designed for warmth, comfort and to be light enough to take hiking. Fitted with a draft collar that wraps our your shoulders, insulated hood and a super comfortable hydrophobic, 20D nylon lining (silk-sheet) interior. The chest area is expanded to give you a bit more room to move around and there’s even an interior pocket to stash your head lamp in.
With the outer fabric being water resistant nylon with a 650 white duck down insulation, this is one warm sleeping bag that’s been tried, tested & passed at 7˚Celsius (although the packaging gives a temperature rating of 6.6˚C).
