{"product_id":"nemo-sonic-neg20d-sleeping-bag-ik4fj","title":"Nemo - Sonic –20D Sleeping Bag","description":"\u003cp\u003e  Built to be the only bag you need from -20°F to 40°F, Nemo updated their Backpacker Editors' Choice award-winning big-mountain bag, Sonic, for even greater warmth, tuneability, and reduced environmental impact. With this bag, they are launching our next-generation Thermo Gills™ with a new multistage zipper system that dramatically increases the usable temperature range of the bag and allows fine-tuning of comfort from within the bag. Sonic's new chevron baffle construction better compartmentalizes down, eliminating migration and keeping the down evenly lofted. Not to mention, it looks awesome. In updating the bag's design, Nemo put a high priority on taking a leap forward in sustainability. The shell and liner fabrics are 100% recycled fabrics and bluesign® approved. The premium 800 FP hydrophobic down is 100% Responsible Down Standard (RDS) certified. They also took years of history in the field to make detailed upgrades, including massaging the profile of the bag, redesigning the draft collar, and bolstering the draft tubes. Their proven Toester™ footbox keeps feet warmer, provides a waterproof barrier against tent wall condensation, and protects down from moisture while drying damp clothes inside the footbox. Adaptable to whatever the mountain throws at it, Sonic continues to reverberate as the ultimate extreme weather companion. \u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e  \u003cli\u003e   Award-winning designis updated for even greater warmth retention and adjustability across temperatures.  \u003c\/li\u003e  \u003cli\u003e   Updated design incorporates 100% recycled, bluesign® approved shell and liner fabrics.  \u003c\/li\u003e  \u003cli\u003e   UpdatedThermo Gills™extend the comfort range with a new multistage zipper system.  \u003c\/li\u003e  \u003cli\u003e   Overstuffed withpremium 800 FP hydrophobic downthat is PFC-Free and 100%Responsible Down Standard (RDS) certified, ensuring humane treatment and traceability throughout the supply chain.  \u003c\/li\u003e  \u003cli\u003e   New chevron baffle construction better compartmentalizes down for more uniform loft and down migration prevention.  \u003c\/li\u003e  \u003cli\u003e   Stretch constructionat the knees for comfortable side sleeping.  \u003c\/li\u003e  \u003cli\u003e   Redesigned draft collaranddraft tubes keep cold air out.  \u003c\/li\u003e  \u003cli\u003e   RedesignedToester™ waterproof\/breathable footboxutilizes a layer of synthetic insulation to protect the down and deliver maximum toastiness for toes.  \u003c\/li\u003e  \u003cli\u003e   Offset zippercreates a thermally efficient seal while an updated profilesecures warmth closer to the body.  \u003c\/li\u003e \u003c\/ul\u003e","brand":"Nemo","offers":[{"title":"Regular","offer_id":45151908724892,"sku":"IK4FJ-REG","price":679.95,"currency_code":"USD","in_stock":false},{"title":"Long","offer_id":45151908692124,"sku":"IK4FJ-LNG","price":749.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/6138\/1276\/files\/sonic_-20_back_angle_1.jpg?v=1753811730","url":"https:\/\/www.gearx.com\/products\/nemo-sonic-neg20d-sleeping-bag-ik4fj","provider":"Outdoor Gear Exchange","version":"1.0","type":"link"}
