TRAVELLER REVIEWS
WHAT TRAVELLERS ARE SAYING.
Nice back pack and vacuum function works well, actually love the colour, light blue. Comfortably holds enough for a long weekend trip abroad or a football away trip which is what it was bought for. Also great as a work bag. Feels like a well made substantial quality product, comfy to wear and easy to carry.
Bag is perfect slightly heavy though i felt but could be due to the fact it is able to carry more luggage than a normal one would do and fits perfectly underneath the seat on small flights.
A very stylish compact backpack, thick fabric, everything exactly as shown in the photo in the product description. Delivery was one week faster than the stated time, packed in three bags.
The only thing to keep in mind is that it is heavy on its own. If you plan to travel with only carry-on luggage, this is important because many airlines have a weight limit of 5kg for carry-on luggage, and here only the backpack weighs ~1.5kg. Otherwise, it's excellent, I recommend buying it.
Excellent travel backpack, lots of pockets. One downside is that it's a bit heavy, and I'm a bit skeptical about the durability of the airtight zipper. For now, it's the best travel backpack; let's see how long it lasts.
I love it, it looks of very good quality, durable, and can hold many things. There are about 10 shirts, underwear, 3 pairs of pants, and many more items. We have verified that it fits perfectly in Ryanair's metal security check. I highly recommend it.
The backpack is of good quality, the material is thick, the fabric is not waterproof, everything is well thought out, I am satisfied and hope it will be comfortable to use.
I'm already using one like this. I ordered a second one for family members. At first glance, it seems bulky. But in reality, it's very convenient for both short and long trips. I don't use a pump.
Great quality, well made. Pump for compression works well. Fast delivery.

FAQ
Questions?
We’ve got you covered.
Still unsure? Here are the answers to the questions travellers ask most.
Will it fit the Ryanair small-bag allowance?
With the 5cm expansion zip closed, KABINBAG measures 40 × 30 × 15 cm. Ryanair currently lists its free small-bag allowance as 40 × 30 × 20 cm. Airline rules can change, so always check before you fly.
Does vacuum compression make the backpack smaller?
No. The vacuum removes trapped air from your clothes so they take up less room inside. The 5cm expansion zip is what changes the bag's external depth.
Does compression make my luggage lighter?
No. It saves space, not weight. Your clothes weigh the same before and after compression.
How long does compression take?
Around 20 seconds with the included rechargeable travel pump.
How long does the compression hold?
The valve is designed to hold through a normal travel day. If the bag relaxes slightly after being moved around, the included pump can top it back up quickly.
How long is UK delivery?
Orders are processed in 1 to 3 days, then shipping is typically 3 to 5 days after dispatch. Tracking is emailed when your order is dispatched.
What if I change my mind?
You have 30 days from delivery to return an unused KABINBAG in its original packaging. If anything arrives faulty or not as described, contact us and we'll make it right.
