What Exactly Are Compression Bags?
Compression bags are essentially heavy-duty plastic bags designed to remove excess air from soft items, shrinking their volume significantly. Think of them as a way to vacuum-pack your clothes without needing a household appliance. For travel, there are two
main types: those that require a small, portable pump or vacuum, and those you simply roll by hand to push the air out through a one-way valve. For the convenience of carry-on travel, the rollable, vacuum-free bags are often the superior choice, as you can easily repack them for your journey home. They come in various sizes, allowing you to pack everything from a single puffy jacket to multiple sweaters.
How to Use Them for Maximum Space
Using a compression bag is straightforward, but a few techniques ensure the best results. First, neatly fold your clothes before placing them inside. While it’s tempting to stuff as much as possible, avoid overfilling the bag beyond its indicated fill line; a proper seal is crucial for keeping the air out. Once filled, press the zip-top closure firmly from one end to the other, ensuring it’s completely sealed. For roll-up bags, start rolling from the zipper end towards the bottom where the one-way air valves are located. Apply firm, even pressure as you roll to force all the air out. You will feel the bag flatten and become incredibly compact.
The Best (and Worst) Items to Compress
These bags work wonders on soft, bulky items. Think wool sweaters, fleece pullovers, thick trousers, and even puffer jackets. Compressing these items can free up an astonishing amount of room in your carry-on, potentially saving you 50% or more in volume. However, they are not ideal for everything. Avoid compressing delicate fabrics like silk or heavily structured garments like blazers, which can be damaged by the process. Items prone to severe wrinkling, such as linen or crisp cotton dress shirts, are also poor candidates unless you have a travel steamer ready at your destination. The tight compression will set deep creases.
The Wrinkle Factor and Other Considerations
The most significant downside to compression bags is wrinkles. Because you are forcefully squeezing the air out, your clothes will emerge more creased than if they were folded or rolled normally. To minimise this, fold items as neatly as possible beforehand. Another key point to remember is that while compression bags reduce volume, they do not reduce weight. In fact, their space-saving magic makes it dangerously easy to overpack and exceed your airline's carry-on weight limit. Always weigh your packed bag before heading to the airport to avoid any costly surprises at the check-in counter.
Are They Better Than Packing Cubes?
Travellers often weigh compression bags against packing cubes. While both help with organisation, they serve different primary purposes. Packing cubes are primarily for organisation, grouping items together and making them easier to find. Some modern packing cubes, known as compression cubes, offer a hybrid approach with a second zipper that squeezes the contents, but they typically don't save as much space as a true air-removal bag. If your main goal is pure, uncompromising space-saving for bulky clothes, compression bags are the winner. If your priority is organisation and minimal wrinkling for everyday clothes, standard packing cubes might be a better fit.
