The versatile backpack for school, university and travel that has seen one buyer through 15 flights

A versatile backpack designed for school, university and short-haul travel has caught the attention of Amazon shoppers, with more than 1,000 bought in the past month. Now it’s on sale. One five-star reviewer says their Xkdoai cabin backpack has already travelled on 15 Ryanair flights without ever being questioned over its size.

The 40 x 30 x 20cm backpack is currently reduced from £25.99 to £16.99 in a limited-time deal, giving shoppers a 35 per cent saving. The offer is for the green version, while black, blue and purple options are also available, with prices varying by colour.

Although it is marketed as a cabin bag, the Xkdoai backpack could be useful well beyond the airport. Its 14-inch laptop compartment, multiple storage sections and comfortable backpack design make it suitable for carrying books and technology to school, college or university, before doubling up as an underseat bag for weekends away.

One five-star reviewer has put the Ryanair-sized backpack through considerably more travel than most people are likely to manage in a short period. They said it had accompanied them on 15 Ryanair flights and that they had never been questioned about its dimensions or asked to put it into the airline's bag sizer.

The reviewer also described it as strong and comfortable to wear, while praising the amount of room for their essentials. They particularly liked the charging cable hole and hidden anti-theft pocket, which they use for their passport and wallet. See the Xkdoai travel backpack deal

The bag measures approximately 40 x 30 x 20cm when fully packed and has a stated 24-litre capacity. It is designed to fit beneath an aircraft seat or into an overhead compartment, while side compression straps can help keep the backpack within its intended dimensions.

For students, the Xkdoai school and university backpack has a 14-inch laptop compartment alongside space for books, notebooks, chargers and other daily essentials. It opens around 180 degrees like a suitcase, which could also make it easier to organise belongings when travelling.

There's a separate wet pocket for toiletries or damp clothing, while the hidden rear zipped pocket is intended for valuables. The backpack also comes with a clear TSA-style toiletry bag designed around the 3-1-1 liquids rule, although travellers should still check the latest security requirements at their departure airport.

The reviewer said the cabin backpack was particularly useful for avoiding additional baggage charges, but stressed the importance of not overfilling it. They said that keeping it within its intended size allowed them to travel without problems, even when staff were checking other passengers' bags.

In fact, they recalled a flight from Birmingham where gate staff were checking the size of many passengers' bags, but said they walked past unhindered with the Xkdoai Ryanair bag. That's one customer's experience rather than a guarantee that airline staff will accept every packed bag, so passengers should always follow the baggage allowance attached to their booking.

Comfort is another reason the £16.99 backpack could work as an everyday student or work bag. The back panel and shoulder straps use breathable mesh, while the padded design is intended to make the bag more comfortable when carrying heavier loads.

The reviewer said they could comfortably carry it throughout the day, including when arriving before hotel check-in or leaving on a late return flight. They also found being able to wear it on their back useful when using public transport.

Beyond travel, the Xkdoai backpack is designed for short trips, daily use and student life, with water-repellent fabric offering some protection from light rain. The listed capacity is intended for around two or three sets of clothing, depending on how bulky your belongings are.

The current £16.99 deal applies specifically to the green 40 x 30 x 20cm version. Black, blue and purple alternatives are also discounted, but prices vary, so shoppers should check the selected colour before ordering.

For anyone starting a new school or university year, the Xkdoai backpack at £16.99 could be a versatile option that covers lectures and everyday laptop carrying as well as short breaks. The 15-flight review is particularly encouraging for travellers who want a bag designed around Ryanair's dimensions.

The reviewer said the bag still looked as good as when they bought it and called it a “good find”, while recommending it for travelling light. At £16.99 for the green version, the Xkdoai cabin backpack is currently 35 per cent below its £25.99 RRP, although the deal is limited time and prices can change.
