Nemo Sonic 0, purchased in 2021, used once. I always stored it in the big stuff bag or hanging in a closet. No stains, smells, tears, or loss of loft. 

$400 shipped - I'm in Lakeside, Oregon. Local pick up a possibility. 

Note, the stuffed hippo does not come with it. He just crawled inside because he thought we were going camping. But I do send stickers with everything I sell, so there is that.
