Mid Winter Masterpiece
When you’re spending days at altitude during the shortest days of the year, the NEMO Sonic -20 Degree Sleeping Bag comes into its own. Lightweight and packable, yet reliably warm well below freezing, this proven alpine bag is a mountaineer’s best friend. It’s stuffed with hydrophobic 800 fill power down, for an unbeatable warmth to weight ratio that won’t quit when conditions get tough. And since overheating can be just as much of a problem, it’s built with multi-stage Thermo Gills™, which let you evacuate excess heat without letting cold air sneak into your bag. Plus, it’s built with bluesignⓇ certified fabric certified throughout, so you can be confident that your new bag was built with consideration for keeping your favorite places cold for generations to come.
