First Impressions

This is a first impression as I have not had an opportunity to sleep outside with it yet. Using synthetic fill for the footbox area is a nice detail. The zippers on the venting "gills" are VERY small and even in brief testing, they sometimes catch on the fabric.

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!

Roomy Bag

It was time to upgrade my bag finally…my old bag was so insanely uncomfortable and only a 20* and I’m a colder sleeper, so I went on a hunt for a 0* bag. I haven’t had an opportunity to take this guy out but let me tell you…it’s so nice and roomy and has enough space for my camping cat. Love the vent features…they unzip on the outside and inside. Can’t wait to take it backpacking.

Poofy, Roomy And Warm

I currently live in my minivan I built out and am traveling and working in Southern Oregon. I tried the Nemo Forte rated at 20 degrees and it was not warm and clearly not rated correctly.. so I returned. Outside temps were around 30 deg. I got this Nemo Sonic sleeping bag rated @ 0 deg and it has been wonderful and rated much more accurately. I am comfortable/warm sleeping in 20 deg weather. I recommend. It’s expensive but worth it.. nothing worse than not getting good rest while traveling in van. Thumbs up. Ps. I chose this sleeping bag in particular because I’m a side sleeper and like to have freedom of movement rather than a typical mummy sleeping bag. It’s great.

Fall In Alaska

Worked perfectly for a fall bear hunt in Alaska. I am 6’1” and purchased the XL and in was nice with a little length to spare.
