Choosing a travel bag: how to compare size, organisation and carrying comfort

A travel bag may seem simple at first glance: choose a size, pack your belongings and set off. In practice, dimensions, carrying options and material are what determine whether a bag works well for a weekend trip, flight, working day or exercise session. A spacious bag can become awkward once it is fully packed, for example. A compact cabin bag may fit under the seat, but offer less room for shoes or a coat.

As a Joybuy Product Recommendation Officer, I filter the most important product information, so you can compare marketing claims with verifiable specifications.

Common pitfalls when choosing a travel bag

1. Looking only at litres

A capacity of 35 or 48 litres does not tell you how the space is organised. A long, narrow duffel bag may be less practical than a slightly smaller bag with a wide opening, inner pocket and easily accessible front pocket. Always check the dimensions and the layout.

2. Confusing “water-repellent” with waterproof

Water-repellent material can provide protection against light rain or splashes. However, that does not automatically mean the seams, zips and contents will stay dry for a long time during a heavy downpour. For electronics, documents and clothing, you may want to take a separate waterproof cover.

3. Assuming every cabin bag fits every airline

Airlines have different limits for hand luggage and bags placed under the seat. Before departure, check the bag’s stated dimensions against your airline’s current rules, even if the product description says it is designed for a particular size. Pay attention to length, width, height and weight, not just the number of litres.

Which specifications are important?

Capacity and dimensions

For a short overnight stay, a 20-litre travel bag may be sufficient, especially if you pack light. A 35-litre travel bag offers more space for clothing, toiletries and an extra pair of shoes. A 48-litre travel bag is worth considering for longer weekends, sports equipment or when you prefer not to pack compactly.

Bear in mind that “foldable” or “expandable” can affect the final size. According to the product information, the Beneunder LC168 has a standard capacity of 20 litres and an expanded capacity of 35 litres. The stated dimensions are approximately 52.1 × 28.2 cm, with a base of around 34 × 18.3 cm.

Weight and carrying options

A lightweight travel bag reduces the weight you have to lift yourself. However, check whether the carrying straps suit the intended use. A travel bag with a shoulder strap is practical for commuting and at the airport, while handles often provide more control over short distances. A luggage strap on the back is useful when you want to slide the bag onto a trolley.

For longer distances, wide straps and good weight distribution are important. A foldable bag is easy to carry as a spare, but make sure the construction does not become unstable when the bag is filled to capacity.

Material and care

Oxford fabric, polyester and similar synthetic materials are commonly used for travel bags. Check the product description for information about durability, zips, stitching and base details. “Water-repellent” is a practical feature for light rain, but it is not a guarantee of complete waterproofing.

Care is usually straightforward: wipe the bag with a damp cloth and leave it to air-dry. Washing instructions vary by model. According to the product information, the Beneunder LC168 should not be machine-washed, bleached or exposed to high heat for prolonged periods.

Frequently asked questions about travel bags

How many litres do I need for a weekend trip?

For a compact overnight stay, 20 litres is often suitable if you pack light. If you are taking extra clothing, shoes or toiletries, it may be better to look at a 35-litre travel bag. A capacity of around 48 litres offers more space, but for air travel you should check the dimensions and weight particularly carefully.

Can I use a travel bag as hand luggage?

That depends on the airline and the type of hand luggage. An under-seat bag must stay within the permitted dimensions for baggage placed under the seat. According to the product description, the Kono bag measuring 40 × 20 × 25 cm is designed around commonly used under-seat dimensions, but rules can change. Always check the conditions stated in your booking.

How can I keep a travel bag usable for longer?

Do not overfill the bag, preferably lift it using both handles when it is heavy and store it somewhere dry. Clean the surface with a damp cloth and follow the manufacturer’s care instructions. For valuable or moisture-sensitive belongings, use a separate protective cover, even when the material is described as water-repellent.
