Compression sacks are bags made of nylon or a similar material that you stuff your clothing into. You pull the fabric tabs to suck the air out of the bag, leaving you with more room in your luggage.
Keep in mind that compression sacks help you to pack more clothing, which ultimately adds to the weight of your luggage. Weight is annoying, and on many airlines around the world, that weight can cost you a LOT of money.
Hikers, backpackers, scuba divers and travelers of all styles can benefit from compression sacks. Hikers can throw their sleeping bags and other gear inside and backpackers can bring more clothing.
First, organize your clothing how you want to find them, with the items you will need first at the top and the ones you might not need at the bottom. Then fold each item lengthwise and roll into a ball.
Place items in the order you’ve chosen into your compression sack. Pull the drawstrings, fold the top over the bag and pull straps until all excess air has left the bag.
Lastly, place the filled compression sack in your luggage or backpack and you’re good to go!
