Lauren loves these things. These Space Bags are great for overlanders. Stash things which you want to carry but do not neccesarily need everyday. For example we use them to store our winter gear, extra towels, blankets, etc. They are waterproof and you will be amazed at how much compression they provide. We opted to go for the “Roll-up” models as opposed to the vacuum seal models. Carrying around a vacuum just wasn’t in the cards for us. Read more reviews here…
