I tested all the compression bags on the market. Here's the one that changed the way I travel and organize my closet.

The BagSlim: integrated electric pump, 5-second compression.

I've been traveling for work for 11 years. Barcelona on a Monday, Amsterdam on a Thursday, back on Friday. I've tried absolutely everything to travel light: ultra-compact cabin suitcases, "wrinkle-free" technical clothing (spoiler: it wrinkles), and of course, compression bags.

For a long time, I thought all compression bags were the same. Plastic bags with a zipper that leaks after two trips, and that require a bulky vacuum cleaner or external pump to work.

I was wrong.

The problem no one wants to admit

Every year, low-cost airlines collect billions of euros in baggage fees. Ryanair, EasyJet, Vueling: the model is always the same. The ticket is "cheap," but as soon as your bag exceeds the authorized cabin dimensions, it's €58, €65, sometimes €74 gone. Per trip. Round trip, that hurts.

The obvious solution? Fit more things into less space. But how, without lugging a vacuum pump in your luggage?

What I discovered after 6 months of testing

Most compression bags have a fatal flaw: they require a vacuum cleaner or external pump. Bulky, slow, unusable on the go. And when the seal isn't perfectly airtight, the air returns and everything reinflates.

The BagSlim works differently, and that's where everything changes.

No external pump. No vacuum cleaner. No accessories.

An electric pump is integrated directly into the bag, rechargeable in 20 minutes via the supplied USB-C cable. The principle is disarmingly simple:

  1. Place your clothes in the bag
  2. Close the reinforced airtight zipper
  3. Press the button once
  4. The pump automatically sucks out the air in 5 seconds

Rechargeable in 20 minutes via USB-C. Cable included.

"No need for an external pump. Just press the button. I tested it on a rainy trip and it's completely waterproof." — Wesly L., verified customer
"So practical! One press and it compresses quickly. I can now take more for my travels. I love it!" — Felix N., verified customer

The concrete results

On my first test trip with the BagSlim, I managed to fit into my cabin backpack: 1 thick down coat, 3 sweaters, 5 t-shirts, 2 pairs of pants, and underwear for 8 days.

Result: zero baggage fees. €58 saved. On a single flight.

The BagSlim reduces the volume of your clothes by up to 50%. Over the year, if you take 6 flights and avoid checked baggage, that's over €300 saved.

But what I hadn't anticipated...

What I hadn't anticipated when ordering the BagSlim was how much it would transform my closet at home. My winter duvets, my thick blankets, my ski jackets: all of that took up an insane amount of space in my wardrobe. Since I started using the BagSlim to store them, I've freed up the equivalent of an entire shelf.

What I like (and what I note)

What I like:

  • Integrated electric pump, USB-C rechargeable in 20 min, cable included
  • 1 simple press of the button, compression completed in 5 seconds
  • Reinforced airtight seal, waterproof even in the rain
  • 50% space saved, for travel and home
  • Available in grey, black, and green

What I note:

  • The zipper may seem stiff at first. That's a sign it's perfectly airtight.

My verdict

After 6 months of testing, the BagSlim is the only one I still use today. Zero external pump, zero hassle, 50% space saved in 5 seconds.

If you take at least 2 flights a year and are tired of paying baggage fees, it pays for itself from the first trip. At €69 (instead of €89 currently), it's the most cost-effective investment I've made for my travels.
