Sierra Designs Spark 30 Degree Sleeping Bag - Women's

The Women's Spark 30 Degree Sleeping Bag by Sierra Designs is rated to 30 degrees F/-1 degrees C. We use partial Flex construction to keep the luxury meter pegged without adding noticeable weight. You'll sleep more comfortably - and more warmly - than ever before with Flex. Just to prove we're still attached to the details - we include all the bells and whistles - like Foot Box Venting - to make our Ultralight Spark as comfortable as bags weighing twice as much.
