When I pack to go somewhere, I pack as light as possible. But sometimes, I need more things than normal and don’t like to bring a big suit case. I’m always putting clothes in trash bags and sitting on it to get the air out. I also have vacuum bags, but not every place has a vacuum to use to shrink the bags for on the way home. These are an ok alternative. They don’t shrink it as much as I need it to shrink, or as much as putting things in a trash bag and sitting on it. They do help as shown in my pictures, but not as much as I hoped. They are good to keep things organized too.
