I love camping. What I don't love is the fact that when you go camping you need to take so many things with you. We rented a cabin that did have beds, but no linens included. That means we had to pack linens, blankets and pillows for a family of 6! Do you have any idea how much space that takes up? We opted to get these. I figured they would be a great way to save space. They were so easy to use. The zipper seal seals and stays put. The screw cap also seals without leaking. We used the home vacuum when packing to go, and used the portable vehicle vacuum when packing to come home. The set does include a hand pump, but we used so many bags that we just wanted them done quickly. These bags can be used with any vacuum. After packing these up we put them in our roof travel rack bag. I drive a mini van so not much cargo space. I am so glad I thought of this great idea. I no longer have to stress over space when traveling. These will definitely be coming along with us for our next trip.
