Sonic 0F/-18C Regular Sleeping Bag

Pinnacle In Mountaintop Rejuvenation.

Long praised as the only bag you need from -20° to 40° Fahrenheit, Sonic™ gets updated for even greater warmth retention and tuneability-while incorporating 100% recycled, bluesign® certified materials for sustainability and stewardship. Updated Thermo Gills™, Toester™ footbox, and over-stuffed with 100% 800FP RDS certified, hydrophobic down, Sonic™ is fine-tuned for frigid weather and environmentally conscious adventure.
