The choice

Two ways through the gate. Only one is free.

Every budget flight, the same choice at the gate. One side keeps paying £75+. The other never pays again.

Without VAULTBAG

  • £75 gate fee every time your bag gets pulled at the sizer.
  • The walk of shame to the sizer while everyone watches you pay.
  • Wrestling a bag that's just barely too big, no matter how tightly you pack.
  • Bleeding your holiday budget dry before you've even landed.
  • Paying the airlines who keep shrinking the rules to trap you.

How it works

Pack. Compress. Walk Straight On.

Built-in vacuum compression shrinks your clothes 50% in under 30 seconds. Pack everything you want and slide it under your airline seat for free. No more £75 baggage fee every flight.

Step 1

Pack Everything You Want

Clothes, shoes, toiletries, stuff it all in. The vacuum compartment holds up to 3 to 4 days of gear. No special folding. No leaving things behind.

Step 2

Compress In Seconds

Click the included portable pump onto the valve and press start. 30 seconds later, your clothes are 50% smaller and your bag is gate-ready.

Step 3

Slide It Underseat

Counts as your free personal item on every airline. No weight limit, so load it heavy. No sizer cage. No £75 baggage fee.

"Walked straight past the gate for free."

"Flew Ryanair twice and avoided baggage fees both times. It slides right under the seat, fits way more than it looks like it should, and I walked straight past the gate for free... already saved over £300."

Perfect for Ryanair Under Seat

Awesome backpack. The compression feature works very well. I managed to fit 4 days worth of clothes and the size is perfect for Ryanair under seat. No more bag fees for me which saves me hundreds of pounds every year. Five stars.

The quality is superb and it does right what it says on the tin. It's incredible how much I can pack using the vacuum compression. Great bag.

My husband got it for me for a trip to Italy and I packed everything I wanted. Slides easily underseat on Jet2 or Ryanair as a personal item. Great purchase. Thanks.

Questions

Frequently asked questions

Isn't there a weight limit on the free Ryanair underseat bag?
Nope, and this surprises most people. Ryanair's free personal bag has no weight limit whatsoever. The only rule is size: 40 × 30 × 20cm. VAULTBAG is engineered to those exact dimensions, so pack it as heavy as you like and walk straight through.
Will it definitely fit under the seat?
Yes. VAULTBAG is built to the exact 40 × 30 × 20cm Ryanair and easyJet underseat specification, not approximated, not "close enough." Every millimetre is accounted for. Soft-sided construction means it compresses naturally into the space without forcing it.
What if the gate agent stops me at the gate?
They won't. VAULTBAG passes every bag sizer because it was designed around them. Thousands of customers have boarded Ryanair and easyJet flights without paying a penny in bag fees. That is the whole point.
How much can I actually fit inside?
The VAULTBAG offers ample space (40 litres when using compression) to effortlessly organise your essentials. Its generous interior comfortably houses clothing, shoes, toiletries, and more, ensuring you're well-equipped for up to 3 to 4+ days of travel. Whether you're embarking on a relaxing holiday or a brisk business trip, this versatile companion ensures you're prepared for any journey.
Which airlines does VAULTBAG work on?
Any airline that allows a free 40 × 30 × 20cm underseat bag, including Ryanair and Wizz Air. It also fits well within the larger free allowances on easyJet (45 × 36 × 20cm), TUI, Jet2, British Airways and most major international carriers.
What's the difference between VAULTBAG and a normal backpack?
A normal backpack is either too big to qualify as a free underseat bag, or small enough to qualify but wastes most of its space. VAULTBAG solves both problems. It sits within the strictest airline size limits and uses vacuum compression to pack 50% more than a standard bag of the same size. One bag, no fees, no compromises.
What materials is the bag made from?
Main fabric: 100% Recycled Nylon 900D Face wax coating & Back PU coating, GRS certified, PFC free.
Back panel fabric: 100% Polyester interlock. Lining: 100% Polyester 230T.
Mesh: 100% Polyester.
Webbing: Polypropylene Webbing, Nylon Herringbone Webbing.
Foams: Polyethylene Foams, EVA Foams, Neoprene Foams.
Is the vacuum pump included?
Yes! For our special offer we're giving away our exclusive VAULTBAG Air Pump free with every order.
How long does it take to ship?
We offer free fast-tracked shipping on all orders. Order processing takes 1-2 business days before shipment. Once your item/s is dispatched, the estimated delivery time is:
• UK: 6-8 business days
• Europe: 6-8 business days
• USA: 6-8 business days
• Australia: 7-12 business days

• Rest of world: 12-20 business days
Is there a money-back guarantee?
