I bought my first set of space bags at a drugstore about 17 years ago, when we lived in an apartment with limited storage, and I needed a compact way to store coats and sweaters during the summer.
The bags were huge, required a vacuum hose to use, and tore easily. They did, however, hold a lot of clothes and fit neatly under the bed, so I didn’t get too wound up about having to patch one and throw out another that tore while I was trying to figure out how to use them.
Space bags have come a long way in the last 17 years. I don’t recommend the off-brand, which are still awkward to use and prone to tear, but the Ziploc brand work fine, and the company has developed a second variety that I really like: travel space bags, which have a little one-way valve at the bottom that allows you to fill the bags about two-thirds of the way up, zip them shut, and then fold or roll down the top, pressing on the items inside to force out as much air as possible out through the valve at the bottom — no vacuum required.
They’re not quite as airtight and won’t flatten down quite as much as the ones that require a vacuum to use, but they’re great for vacation (I assume you don’t travel with a vacuum cleaner and hose attachments) and even better for storing my surplus T-shirts on the top shelf of our bedroom closet so I’ve got replacements on hand when one wears out or gets stained. If you’re creating a capsule wardrobe, they’re also a nice way to store items you aren’t quite ready to get rid of altogether but are pretty sure you don’t really need.
Space bags can be pricey, and the travel kind aren’t always available when I need them, but I found a cheap alternative in the food-storage aisle at Target: plain old 2.5-gallon Ziploc bags.
Fill ’em halfway, zip ’em most of the way shut — leaving about a quarter-inch gap at the end for air to escape — and fold or roll ’em up, starting at the bottom and pressing out as much air as you can before you zip them the rest of the way shut. They don’t compress quite as much as space bags, but they’re cheap, hold several T-shirts, and work pretty well in a pinch to keep items organized in a relatively compact manner on a closet shelf or in a backpack.
Disclaimer: Ziploc didn’t give me anything to write this review. I just found these products handy and thought somebody else might, too. Nobody ever gives me anything to get me to blog about it. I’m not popular enough for that. Poop.
