NEMO Equipment Sonic Down Mummy Sleeping Bag

NEMO EQUIPMENT SONIC DOWN MUMMY SLEEPING BAG

Sonic is built to be the only bag you need from -20°F to 40°F. The Backpacker Editors’ Choice award-winning big-mountain bag offers exceptional warmth and tuneability with a reduced environmental impact. This bag features our next-generation Thermo Gill vents, with a new multistage zipper system that dramatically increases the usable temperature range of the bag and allows fine-tuning of comfort from within. Sonic’s chevron baffle construction better compartmentalizes down, eliminating migration and keeping the down evenly lofted.

FEATURES

• Thermo Gill vents allow for temperature regulation in variable mountain climates without letting cold air in.
• Premium materials such as a 20D nylon ripstop shell and a smooth 30D nylon taffeta on the interior increase durability and comfort.
• Stretch construction at the knees allows side sleeping.
• Stuffed with 800 FP hydrophobic down that is 100% RDS-certified. Products certified to the Responsible Down Standard (RDS) contain down or feathers from farms certified to animal welfare requirements.
• Down-filled draft collar and draft tubes create a secure seal to keep cold air out.
• Toester waterproof/breathable footbox relies on an additional layer of synthetic insulation to reduce cold spots.
• Offset zipper creates a thermally efficient seal.
• Contoured profile secures warmth closer to the body.
