Sierra Designs Lazer 30 Sleeping Bag: 30 Degree Synthetic

Sierra Designs Lazer 30 Sleeping Bag: 30 Degree Synthetic One Color Long/Left Zip. Sierra Designs filled the Men's Lazer 30 Degree Synthetic Sleeping Bag with PrimaLoft Eco recycled insulation and added Flex sidewalls for more comfort. Not every person sleeps on their back with hands at their sides, so Sierra Designs' Flex system expands and contracts to let you move around freely without creating cold-air pockets. Overlapped baffled construction eliminates cold-spots on the seams, and the footbox vent lets you cool off during warmer tent-bound nights. The Lazer Sleeping Bag makes its low two-pound weight thanks to ultralight materials and a half-length zipper.
