Traveling during the cold weather months is uniquely tricky. Not only do you have to deal with bigger crowds and longer lines at the airport during the holiday season, but packing bulky coats and enough sweaters for frigid winter temps isn’t easy.

Rather than sit on your suitcase to squash everything down until it closes, invest in these Travel Space Saver Bags while they’re on sale on Amazon. Right now, you can get a set of eight bags in different sizes for just $21.95.

8-Pack Travel Space Saver Bags Vacuum Storage, $21.95 (Orig. $29.95)

Shoppers on Amazon give these space-saver bags 4.3 out of five stars, and more than 3,200 people have left ratings for them. Unlike traditional space-saving bags that use a vacuum, these bags just require a simple rolling technique to push all the air out. Fill the bag with your items, zip the bag closed three times, then firmly roll the bag to force the air out. Once the air is removed, you can either keep the bags rolled and pack them in your suitcase or can stack several flattened bags in your luggage. Pretty amazing, right?

With travel back, shoppers rave about how convenient these space-saver bags are.

“Amazing for traveling,” one shopper titled their review. They went on to write, “I was able to pack everything that I needed with room to spare!”

Another shopper commented, “My clothes came out of the bags looking the same as when they were packed; clean, no wrinkles, did not shift during transit. Makes packing so much easier.”

While these space-saver bags are great for neatly and efficiently packing your luggage, they can also store seasonal items like shorts and swimsuits in the winter or coats and sweaters in the summer.

It’s not clear how much longer these handy space-saver bags will be on sale, so add them to your Amazon cart ASAP and check out before the price goes up.
