Grigorios O.wrote a review of NEMO Equipment Inc. Sonic 0 Sleeping Bag: 0F Down on March 20, 2019
Familiarity: I've used it once or twice and have initial impressions
I bought this based on the excellent reviews it got from outdoorgearlab.com and was not disappointed. It has lots of space which is great for me, as I get a bit claustrophobic in sleeping bags. Very warm and light.
