I bought the vacuum bags and used them on a five day motorcycle trip when all I had for packing space was one side saddlebag. I fit everything I needed using two vacuum bags. I was amazed at how much I could fit in and so glad I had the bags to use. no one could believe I had everything I needed, including five days of clothing, one of which was a big hooded sweatshirt, even had a swimsuit and cover-up
