What RebelPak owners say

Straight under the seat, no questions

Flew Ryanair to Alicante and walked past the sizer without breaking stride. Five days of clothes in it.

Better than the one I paid more for

My last bag was sold as cabin approved and it was not. This one is the actual under-seat size.

Bought a second one

Got one for me and one for my partner. Cheaper than two gate fees on one holiday.

Trusted by travellers who stopped paying at the gate

Paid for itself on the first trip

I have been charged at the gate twice before. Not this time. The pump takes about thirty seconds.

The laptop pocket sold it

16in MacBook goes in the padded section and it still slid under the seat on easyJet.

Does what it says

Sceptical about the vacuum thing. It genuinely takes a jumper down to nothing.

RebelPak vs Other "Cabin" Bags

Most bags sold as cabin approved are sized for the overhead locker, not the space under the seat.

Two ways through the gate.

Same flight, same bag sizer. One of you repacks on the floor and hands over a card. The other walks straight past, because the bag was built to the size the airline actually allows.

Frequently Asked Questions

Will it actually fit under the seat? +

It is built to 40 × 30 × 20cm — exactly the personal-item size Ryanair publishes, and well inside easyJet’s 45 × 36 × 20cm. The airline checker on the product page lists your own airline's allowance before you buy.

Does the compression need power at the airport? +

No. The pump charges over USB-C and runs from a power bank, so there is nothing to plug in while you are travelling.

Can I take this as well as a cabin bag? +

Yes. It is sized as your free personal item, so it goes under the seat in addition to any cabin bag you have paid for.

Which airlines does it work with? +

Any carrier with a personal-item allowance of 40 × 30 × 20cm or larger, which covers most European airlines. The checker on the product page lists them individually.

How long does delivery take? +

Black is in stock and leaves us within 3 working days, by Royal Mail Tracked 24. Express delivery at checkout aims for the next working day after dispatch, though Royal Mail do not guarantee it. Every other colour is ordered in, so allow about 14 working days.

What if it does not work for me? +

You have 45 days to send it back for a full refund, unused and in its original packaging.
