Sierra Designs Spark 30 Sleeping Bag: 30 Degree Down - Women's

Sierra Designs loaded the Womens Spark 30 Degree Down Sleeping Bag with comfortable features and still managed to get its weight down to a low 25oz. By combining a half-length zipper with a foot vent, the Spark Sleeping Bag provides the same temperature adjustment of a full zipper at a fraction of the weight. Thanks to Sierra Designs Flex construction, this 800-fill down bag moves with you as you sleep to eliminate cold-air pockets while still letting you relax in whatever position you like.
