The next time you head into the Three Sisters Wilderness backcountry, you'll overcome any weather surprises and keep warm with the ThermaRest® Antares™ 20 Degree Down Sleeping Bag. Zoned insulation features a baffled construction sewn through down insulation on the side. This prevents the down from slipping and creating cold spots. The and a fabric only bottom designed to attach securely to your sleeping pad (up to 25 in) using the SynergyLink Connectors—this means your sleeping pad will provide the insulation and you'll be spared the weight of more insulation on the bottom of the bag. If the thought of being confined in a mummy bag scares you, this bag's Efficient Comfort Fit gives you more room in the torso so you can move freely throughout the night. Rest assured when heading out on your next adventure—you'll have no problems finding the Sandman while you're in this sleeping bag.
