How should the bag be stored? Is it OK to store it in the compressed bag?

Asked by: Frank
Down sleeping bags are not as susceptible to damage from compression as synthetic bags. However, storing any sleeping bag in a compressed state for extended periods of time will reduce the life of the bag. When not in use, the sleeping bag should be kept loosely in its included storage sack and hung in a cool, dry place.

Hi, for this bag (but also in general) as a 5' 10 1/2" female would the regular size be okay? Also, would this bag compress much in a compression sack? Thanks!

Asked by: KiCa
The Lithium Sleeping Bag in a regular length is a perfect fit for an individual up to 6 feet tall. This bag will pack into a 7.5 x 16 inch stuff sack and, due to the 800-fill down, can compress to approximately 2/3 that length (7.5 x 11").

Us the left zipper a standard zipper? Looking to zip with a right zipper bag.

Asked by: SCHAWANNA
​The Lithium Sleeping Bag has a two way YKK zipper. It will zip together with most other Marmot bags that have a right zipper.

What is meant by "second zipper"?

Asked by: ShakyKnees
The Lithium bag has a second shorter zipper on the right side of the bag for added ventilation and access.
