The half zip on the right side of the bag provides freedom of movement for both arms additional ventilation and means the top third of the bag can be folded down as a mini quilt. The full length two-way left side zip and separate foot zip transforms the bag into a full quilt for when the mercury climbs higher than expected.If its warmth youre after close all the zips pull the cord locks tight to drag everything in and relax in luxurious comfort.
