Jack E.wrote a review of Marmot Arroyo Sleeping Bag: 30 Degree Down on April 4, 2010
I've used this bag twice and both times I was disappointed. Both times the temps got down to mid to high 30's but I was not warm and tosty like my other 2 Marmot bags. I don't know exactly what the problem was, but I was disappointed in it's performance. I own a lot of Marmot products and this is the 1st time their bag has not kept me warm, I have a Marmot Atom 40* bag that I can take down to the low 30's and be warmer in it than in the Arroyo. I'm only keeping it because I got a killer deal and I'll end up using it for an extra summer bag for my friends.
