NEMO Sonic Down Mummy 0deg Sleeping Bag

The NEMOA(R) Sonic Down Mummy Sleeping Bag is built to be the only bag you need when the weather turns frosty. The Backpacker Editors' Choice award-winning big-mountain bag offers exceptional warmth and tuneability with a reduced environmental impact. This bag features 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. The shell and liner fabrics are 100% recycled fabrics and bluesignA(R) 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.
