Long term storage:
When storing your Zenbivy, it's important to give it space. To protect the longevity of the down, you never want to store it long-term fully compressed. Each Zenbivy Bed comes with a large mesh storage bag. When coming back from a trip, we'd recommend pulling your Zenbivy out of its Dry Sack as soon as you get home. If it's a nice sunny day, you can hang it up outside for a bit to air it out and let any moisture completely evaporate before stuffing it loosely into the mesh bag.
Each of the down chambers is fully baffled and separated from other baffled chambers, so down can’t migrate and never needs to be “redistributed”. Simply shake the quilt out and let it sit in a warm room and it will regain its loft even after being semi-compressed for a very long time.
