The Sierra Designs Lazer 30 Degree Sleeping Bag is a 30 degree sleeping bag for a warm sleep on cold nights. The synthetic insulation, PrimaLoft Eco is made of recycled plastic and soda bottles, or maybe it was pop bottles, or soft drink bottles. Either way, it's helping out the earth one sleeping bag at a time. The hood cinches down and softly cradles your head while the footbox ventilates if you become too hot. The middle of the bag is functional as well, specially designed to flex, where you move the most throughout the night. Pew, pew, pew. That was the sound of the cold being shot down via sleeping bag.
