How to Use

Nothing could be simpler.

In just a few seconds, place your clothes inside the backpack, close the vacuum compartment, and remove the air using the included pump. As the air is compressed, your items instantly take up less space allowing you to carry up to twice as much without increasing the bag’s size.

Once compressed, you can easily add extra clothing and accessories on top of the vacuum compartment, using the remaining space as a bonus. The backpack also features dedicated and independent compartments for your laptop, dry zones designed to protect against humidity, and quick-access pockets for essentials like your passport, wallet, and travel documents always within reach.

Frequently Ask Questions

FAQ

Will the bag really fit every airline?

Yes. Our bag follows the strictest cabin size on the market — Ryanair’s 55×40×20 cm standard.

Because it meets this requirement, it is accepted as a cabin bag by all major airlines, including:


easyJet

Ryanair

British Airways (BA)

Jet2

Wizz Air

Virgin Atlantic

In short: if it fits with Ryanair, it fits everywhere.

How does the vacuum compression actually work?

The backpack includes an airtight compression chamber. Once your clothes are inside, you attach the included pump and remove the air in a few seconds. As the air leaves, your clothes flatten and lose up to 30–50% of their volume, giving you much more space without adding weight.

What if I need to repack once I arrive?


No problem the compression system can be reused anytime.

Just place your clothes back in the chamber, attach the included pump, and remove the air again.

It only takes a few seconds, even in a small room or on the go.

Will vacuum compression make my clothes wrinkled?

No the compression chamber is designed to remove air without crushing your clothes. Because everything stays flat and tightly held in place, your outfits come out smooth and wrinkle-free, even after long trips

Do you provide tracking information?

Yes, Every order includes a tracking number which will be provided via email or text once your order is fulfilled.

Won’t my bag become too heavy if I pack more?

Compression reduces volume, not weight so the weight of your bag doesn’t change.

You’ll still need to respect your airline’s weight limits, but you can pack much more into the same cabin size.

Does it fit a 15" or 17" laptop?

Yes the padded laptop compartment fits both 15" and 17" laptops securely.

Your device stays protected thanks to the reinforced back panel and shock-absorbing padding.

Does it fit under the seat as well as in the overhead compartment?

Yes. When compressed, the bag slides under most airline seats and fits easily in overhead bins. t’s designed to stay within the strictest cabin limits, even on low-cost airlines.

Will the zippers hold when the bag is full


Absolutely. The zippers are reinforced, high-tension, and designed specifically for overstuffed travel bags. They’ve been tested to hold up to 12 kg and more without tearing or splitting, even when the bag is fully compressed.

Is the bag really covered by a 2-year warranty?

Yes it includes a 2-year warranty that covers all manufacturing defects.
