Space Bags are vacuum sealed storage bags for storing everything from bulky seasonal cloths to that extra comforter. Start by packing your bag and then use any vacuum with a hose to suck out the air from your space saving bag. Space Bags protect the contents from moisture, mildew, and bugs, but are water and air tight to keep moisture out and prevent molding. These durable and reusable bags will triple your storage space and keep your items vacuum fresh.
