rated 4.0 of 5 stars

This is a very economical lightweight down bag that performs well and I would recommend this as a good bag to use for a hike of the JMT.


  • Low cost
  • Warm bag that is good to rated temperature


  • Orange zipper (kind of "loud" for me)
  • Draft collar has minimal fill

I was planning to hike the JMT this summer and really wanted to get the base weight I would be carrying down as low as I could without spending a lot of money. I had a zero degree North Face down bag that I have owned and loved for over 25 years, but it was overkill for the JMT and was also heavy compared to a three-season bag, so in my search for a bag for the JMT I came across this 20 degree bag from Outdoor Vitals.

Since I was buying a new pack, tent, and sleeping bag for this trip to get my weight down I was very focused on getting the most bang for my buck and this bag fit the bill. I am 5'11" tall and 195 lbs and I purchased a regular size bag and I had plenty of room when using the bag.

While I was not able to do the entire JMT this summer, I did get two five-night section hikes along the trail done and this sleeping bag worked out great. My coldest night maybe was only in the upper 30s and the bag was very warm if not almost too warm, so I don't envision any issues using it on trips down to its rated temperature.

While the sleeping bag did come with a completely functional compression stuff bag I ended up using another compression stuff bag that I already owned that was a few ounces lighter to help get the base weight of my pack down to about 21 lbs.  

Overall I am very happy with my purchase of this sleeping bag.
