The NEMO Sonic 0 sleeping bag is your cold-weather retreat after a long day skiing, snowshoeing, or snowboarding. Ultralight, moisture-resistant down and draft-stopping features ensure you a warm place when the weather is cold and built-in "gills" allow ventilation when needed.
This bag is insulated with 800 fill hydrophobic down. That means the down clusters resist moisture longer than untreated down and dry faster when they do get wet. The down is also PFC-free and certified with the 100% Responsible Down Standard (RDS) recognized for traceability throughout the supply chain. The interior of the bag is lined with a comfortable 20D polyester, and the outer shell is 20D nylon--both treated with a DWR coating. The footbox is reinforced with 40D nylon fabric and waterproof construction, as well as a DWR coating. All of the fabrics are bluesign certified and 100% recycled for sustainability.
This bag has a mummy shape for optimal heat retention, and the chevron-shaped baffles are designed to keep the down lofty throughout the bag and minimize down migration--keeping you warm without cold spots. The bag features two zippered openings on the front, with a fabric barrier (but no fill) between them. These Thermo Gills let you regulate the bag's warmth based on conditions and your comfort level. Two sets of zippers, one on the interior, the other on the exterior, make it easy to adjust the bag's heat retention and provide draft-less ventilation.
A draft collar and draft tube prevent cold air from entering your warm bag. A contoured hood with a drawstring cord lets you can cinch down the opening and further block drafty air. The Toester footbox is tailored for foot comfort and the waterproof construction protects against tent wall condensation on cold mornings. There's also a small, zippered pocket at the top of the bag for your phone or other small essentials. An included compression stuff sack helps you squeeze the bag down to its smallest packed size.
The NEMO Sonic 0 sleeping bag is available in Short (fits up to 5" 6"), Regular (fits up to 6'), and Long (fits up to 6' 6").
