Rating: rated 4 of 5 stars

Purchased this bag for my daughter to use this past summer. We went backpacking a couple of times and with the temps getting down to around 50 degrees she was totally warm. Unfortunately, I can't offer a judgment on it nearer its rating.


  • Lightweight due to the down
  • Packs down small when using a compression sack
  • Affordable, entry level down bag


  • None so far

My daughters had been using a couple of Marmot 30 degree synthetic bags for years and were always cold. Since they wanted to do more backpacking this past summer, I started looking for affordable down bags. The Kelty site has a Sale area and I found this bag there for around $110. It works well for one of my daughters but is a bit too short for my other daughter, so we only got one.

She says it kept her warm on all the nights we camped. I think the lowest temp was around 50 degrees. The backpack she used this summer is a TNF Terra 45 and this sleeping bag packed small enough to fit in the bottom pocket along with her camp pillow. We used a compression sack which made a big difference in packability.  

If I'm able to get her to camp this fall, I'll report on her comfort with these nights that are now in the 30s.

This bag is a good deal if you are looking for down, but aren't willing to pay a hefty price. It doesn't pack down quite as small as I would like, and sleeping at 32 degrees I have felt a little chilly. I am a cold sleeping, and I would rate this closer to a 30 degree bag.

The fit is comfortable, not too baggy and not too tight. The draft tube around the collar doesn't cinch, which would be a nice addition for a little extra security and warmth.


  • Inexpensive
  • Durable


  • Heavy
  • Doesn't pack down

Overall, this is a decent bag. It sleeps a little colder then its 20 degree rating.  I have had to throw a liner in there for below 32 to keep me warm. It isn't drafty, but it could use a little more insulation around the torso. I also think that if there was netting between the seams, this would help prevent down from clumping or shifting from the top of the bag to the sides when you are sleeping at night.  

Overall fit and comfort of this bag is average.  The hood is a little big/flat for a loose fit, but if you cinch it down it fits nicely. Also, the draft tubes around the neck don't cinch and it needs a better tab to keep the cold zipper off your face at night.  There is plenty of room in the bag to move around, but it isn't too roomy.  

The bag doesn't compress as well as some other 20 degree bags that I have had in the past, and it is a little heavy, but for the price it is a good deal. The stuff sack, however is really awful. It is possible that the bag might compress smaller with a better sack. The clips don't stay on the straps at all and I have already lost one, so now I can only cinch three sides instead of four. I have only slept in the bag on one really really damp night, and it the shell was not very water resistant.

I have already put about 30 days on the bag this season, and so far it is holding up well.
