Pros & Cons

Reasons to buy:

User Reviews

  • Soft and comfortable – like sleeping on a cloud.
  • Easy to use zipper.
  • Great loft.
  • Foot box is wide and comfy for your feet.
  • The water resistant down provides added protection from the elements.
  • Can save hundreds of dollars by going with this bag instead of with a higher end competitor’s.

Expert Reviews

  • It hits a value sweet spot.


Reasons NOT to buy:

User Reviews

  • No draft collar which is a bummer for a zero degree bag.
  • Doesn’t compress as well as other bags that have higher rated down.

Expert Reviews

  • Slightly bulky and harder to compress.
  • Shell material is not as durable as some higher end alternatives.
  • 650 fill down is good but not great. There are other (more expensive) bags on the market that use higher quality down with higher warmth-to-weight ratios.


The Marmot Never Summer 0 Degree Down Sleeping Bag provides outstanding performance for the price. While other bags may be warmer and lighter, the Never Summer won’t break your bank account and still provides impressive warmth with a smart design.
