So.... I guess the OutDoor Friedrichshafen (the organization that gave out the award) doesn't keep up with developments in the USA -- 'cuz the Haglöfs bag is a less effective version of the Feathered Friends Rock Wren.
Yes, the Haglöfs is lighter (but I bet it wouldn't EN test to the same temperature as the Rock Wren), but what's the point of stumbling around with your arms bound to your sides inside the warm bag.
The Rock Wren allows you easier in/out access with a partial zipper, and it has arm zippers, so you could actually walk around and drink a cup of coffee in the morning, with the bag acting as a giant, ankle-length down vest!
Check out the Rock Wren, OutDoor Friedrichshafen! ;^)
