The Ultra Elite 20° Sleeping Bag - Long will have you pressing snooze on your next overnight adventure. Its ElixeR™ Micro synthetic insulation uses a unique blend of three fibers for maximum warmth, soft handfeel, and high loft. After an epic day on the mountain, give your feet a rest in the roomy wrap-around footbox. The 3D hood construction limits heat loss, while the slim mummy fit reduces weight and increases thermal efficiency. If the interior gets too warm, use the full-length two-way zipper with an anti-snag slider to get some air. Tuck small items into the internal stash pocket for easy access.
