Why travelers pick Stowway
A normal backpack runs out of room. A hard-shell carry-on costs you a fee. Stowway does what neither can.

"Did 10 days in Italy out of just this bag. The valve thing actually works. I fit way more than my old North Face and walked straight past the bag-drop queue."

"Flew Ryanair four times and never paid a cabin-bag fee once. It slid under the seat every time. Honestly paid for itself on the first trip."

"Genuinely surprised how much it swallows once you compress. Laptop sleeve is solid. Took a star off only because I wish it came in more colors."
Sofia M.✓ Verified

"The trolley sleeve is the detail I didn't know I needed. It slips right onto my suitcase. Back panel is comfy even when it's stuffed full."

"Bought the 2-pack for me and my wife. Two weeks in Japan, carry-on only. The compression is legit, not a gimmick. Would buy again."

"I'm a chronic over-packer and this finally fixed it. Squeeze the air out and suddenly there's room for the shoes too. Gate agent didn't blink."
Questions, answered
Yes. The Stowway is built to 40×25×20cm, within the personal-item allowance for Ryanair, Wizz Air, easyJet and most major carriers, so it slides under the seat in front of you for free. Always double-check your specific airline and fare, as allowances occasionally change.
No. The one-way valve does the work. You simply press down on the bag with your hands and the air escapes through the valve but can't get back in. It takes about 30–60 seconds. There's no electric pump or vacuum cleaner.
Compression squeezes out air, not your fabrics, so it's gentle. Roll your clothes before compressing for the best results and minimal creasing. Most travelers find their clothes come out flatter and tidier than in a normal bag.
Around 30L when expanded, comfortably a week of clothes for most people, plus shoes, tech and toiletries. Once compressed it flattens down to clear strict gate sizers.
Yes, there's a dedicated padded sleeve that fits laptops up to 16", with a separate slot for a tablet.
The shell is water-resistant and made from tough, tear-proof fabric that shrugs off rain and splashes. For total submersion we'd still recommend a rain cover, but for everyday travel weather you're covered.
Every Stowway is backed by a 30-day money-back guarantee. If it doesn't help you pack more and travel lighter, send it back for a full refund, with no questions asked.
