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. (Not to mention, it looks awesome.)The shell and liner fabrics are 100% recycled fabrics and bluesign approved, and the premium 800 FP hydrophobic down is 100% Responsible Down Standard (RDS) certified. Years of history in the field yielded detailed upgrades on this bag, including a perfected profile, redesigned draft collar, and bolstered draft tubes. Our 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. All NEMO products carry a lifetime warranty against defects in workmanship and materials to the original owner. Review: worth the money - Nice and toasty, just a great design. Review: zipper problems - Nice and warm at +23 degrees F and windy. The zipper was sticky and jammed the first trip. Brought it home and unstuck it with great force. The next trip I had the same zipper issues so I had to return it. Too bad, it's a really nice bag with plenty of room for me. ## Features - Nylon - Award-winning design updated for even greater warmth retention and adjustability across temperatures. - Constructed with 100% recycled, bluesign approved shell and liner fabrics. - Second-generation Thermo Gill vents extend the comfort range with a new multistage zipper system. - Overstuffed with premium 800 FP hydrophobic down that is PFC-Free and 100% Responsible Down Standard (RDS) certified, ensuring humane treatment and traceability throughout the supply chain. - Chevron baffle construction better compartmentalizes down for more uniform loft and down migration prevention. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09RN9L16W | | Additional Features | Next-generation Thermo Gills, Chevron baffle construction, Updated profile, Stretch construction at the knees, Draft collar and draft tubes, Toester waterproof/breathable footbox | | Age Range Description | Adult | | Best Sellers Rank | #508,559 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #877 in Camping Sleeping Bags | | Brand Name | Nemo | | Closure Type | Zipper | | Color | Goodnight Gray / Torch | | Customer Reviews | 4.2 4.2 out of 5 stars (13) | | Fabric Type | Nylon | | Fill Material Type | Down | | Item Dimensions L x W | 77.95"L x 31.5"W | | Item Weight | 1.76 Kilograms | | Manufacturer | Nemo Equipment | | Manufacturer Part Number | 811666034540 | | Material | Nylon | | Maximum Height Recommendation | 72 Inches | | Model Number | NM-SNC3-R | | Occupancy | 1 Person | | Seasons | Winter | | Shape | Mummy | | ShellMaterial | Polycarbonate | | Size | Standard | | Sport Type | Camping | | Temperature Rating | Extreme | | UPC | 811666034540 | | Warranty Description | Every NEMO Product is backed by a lifetime warranty against defects in workmanship and materials. | ## Product Details - **Age Range (Description):** Adult - **Brand:** Nemo - **Color:** Goodnight Gray / Torch - **Material:** Nylon - **Occupancy:** 1 Person - **Seasons:** Winter - **Shape:** Mummy - **Sport:** Camping - **Temperature Rating:** Extreme ## Images ![Equipment Sonic Down Mummy Sleeping Bag - Image 1](https://m.media-amazon.com/images/I/61TPn52CejL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ worth the money *by I***R on July 9, 2025* Nice and toasty, just a great design. ### ⭐⭐⭐ zipper problems *by R***S on April 15, 2022* Nice and warm at +23 degrees F and windy.
