Sierra Designs Women's Dream Weaver (15 Degree) (2001):
Sierra Designs has focused on the interaction between humans, sleep and sleeping bags for the past 4 years. One of the results is the Dream Weaver, a bag specifically designed for a woman's size and shape as well as lower metabolic rate. The Dream Weaver maintains its thermal performance level whether you sleep on your back, side or stomach. And since everyone moves an average of 40 times a night, the Dream Weaver is designed to let you shift positions without losing heat.
