I absolutely love space bags. I have so much in them. I used to store all my off season clothing in huge Rubbermaid trunks and they just took up too much space. The newer space bags are much better than the older ones from years ago. I have all my extra blankets, pillows and off season clothes in them, in the unfinished basement and they stay just fine. Once in awhile I get one that puffs up, but it's usually because I didn't get the zipper closed properly on it when sucking the air out. I bought some from QVC that were actually inside of a 2 handled cloth storage box and the space bag was attached. I bought a dozen of those and they store so much inside and they store nicely on a shelf with the side handles.
