TECHMILLY Collapsible Mesh Pop Up Laundry Hamper with Sturdy Handles and Side Pocket - Portable Foldable Clothes Baskets for Dorm, Bathroom & Travel Storage (with Drawstring, Black)

I got a couple of collapsible mesh laundy hampers with drawstring tops and my down sleeping bags seem to do well in those. They're nice because the bags are light enough that I can stack the hampers and the lower hamper doesn't get squished.
