Sitka has launched their warmest and lightest sleeping bag with the HyperDown bag. It is comfort rated at 15 degrees, uses 900 fill power Allied Down with a treatment that is extremely water resistant, and tips the scale at 2 pounds. Very impressive specs!
Expect a full written review soon as I've had the good fortune to use this bag last fall/winter to see what it's limitations are and where it shines. In the mean time ask questions and go check out the full specs here: Sitka HyperDown Sleeping Bag
