Best 0 Degree Bag I've Owned!

I recently purchased the 0 degree bag for a bike-to-ski trip in Iceland, so I needed it to work in a variety of conditions (cold, wet, snowy, windy, you name it), and be versatile enough to pack into panniers, backpacks, and beyond. The bag was perfect and outperformed my expectations. I stayed warm on cold nights and loved the ability to open the gills for added breathability, which was crucial in never feeling too swampy if it was a warm night. I ended up swapping the stock stuff sack for a waterproof compression sack, and it packed down quite small for a 0 degree, fitting well into my panniers and 35L backpack when skiing. I'm 5'9" and the regular length fit me well - my pillow tucked very nice and snugly into the hood, so sleeping was always quite comfy and cozy. No complaints, issues, etc. Happy customer here!

Built to be the only bag you need from -20 Degree F to 40 Degree F, Nemo has 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 their next generation Thermo-Gills with a new multi-stage 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 Sonic design, Nemo put a high priority on taking a leap forward in sustainability. The shell and liner fabrics of Sonic are 100% Global Recycled Standard (GRS) recycled and bluesign approved. The premium 800FP hydrophobic down is 100% Responsible Down Standard (RDS) certified. Nemo 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.

Nemo's 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.
