The Elite 350 Sleeping Bag from Terra Nova is designed to offer the performance you expect from a superlight down insulation. Designed for summer backpacking trips where size & weight need to be kept to a minimum. Fitted with locking zip sliders to keep the cold out, you stay comfortable all night. With a 3D hood & drawstring closure, you stay nice & snug. When the time comes to either get in or out, the zip guards stop the zipper from getting caught on the fabric & with the up & over zip pull, zipping & unzipping is easy whether you are in the bag or out.
