Travel Suitcase: The Ultimate Buying Guide for 2026

Hard-shell or Soft-side Suitcase: Which to Choose?

This is the first question to decide. Both technologies meet different needs, and the wrong choice is paid for on every trip.

The advantages of a hard-shell suitcase

A hard-shell suitcase protects its contents much better. In the event of an impact on a luggage carousel or rough handling in the hold, the shell absorbs impacts without your belongings suffering. Other strong points:

• Waterproof: no infiltration in case of a damp hold or rain on the tarmac
• Integrated TSA lock: essential for flights to the USA, useful everywhere
• Simple maintenance: a wipe with a sponge is enough
• Structure remains intact even when fully packed
• 360° double wheels: smooth maneuverability in airports and train stations

For regular use, i.e., more than 3 trips per year, the hard-shell suitcase is the only rational choice. Consult our hard-shell vs. soft-side suitcase guide for a deeper comparison.

The advantages of a soft-side suitcase

A soft-side suitcase offers slight flexibility to tuck in a last-minute purchase. Lighter when empty for certain models, it is suitable for occasional travelers who prioritize capacity over protection. The GYL Évasion collection in waterproof polyurethane represents the best a soft-side suitcase can do: lightweight (2.2 kg in the cabin), durable, equipped with 360° double wheels, and covered by the worldwide warranty.

Its limitations: it absorbs moisture on low-end textile shells, deforms over time, and offers less protection for fragile items. For professional or intensive use, it quickly shows its limits.

Polycarbonate, Polypropylene, or ABS: Which Material for Which Suitcase?

The shell material is the primary indicator of durability. Three materials dominate the hard-shell suitcase market, with major differences in resistance and longevity.

Polycarbonate: the choice for regular travelers

Polycarbonate is the reference material for high-end suitcases. Unlike ABS, which can crack under a violent impact, polycarbonate deforms slightly and then regains its shape: this is called shape memory. The Intemporelle and Trunk collections by GYL are made from 100% high-density polycarbonate: lightweight, scratch-resistant, and covered by the worldwide warranty.

Polypropylene: solid and accessible

Polypropylene offers excellent rigidity at a more accessible price. It resists deformation well and is perfectly suited for travelers who depart 2 to 4 times a year. The Citadine and Signature collections by GYL use this material with the same exacting finish and the same worldwide warranty.

ABS: to be avoided for regular use

ABS is the material of entry-level suitcases. Heavier and more fragile, it can crack under a strong impact in the hold. If you travel more than 2 times a year, ABS is not a good investment. Our comprehensive guide to hard-shell suitcase materials details the technical differences to help you choose.

Which Travel Suitcase Size to Choose?

The duration of the trip is the most reliable criterion for choosing the right size. Here are practical benchmarks based on the actual capacities of GYL suitcases.

Weekend (2-3 days): the S cabin suitcase (55 cm, 35 L)

For a weekend, the S cabin suitcase is sufficient and optimal: it goes into the cabin with you, avoiding luggage wait times and checked-bag fees. With 35 liters, it holds 3 to 4 outfits, a toiletry bag, and a laptop. GYL S-size models weigh between 2.2 kg (Évasion soft-side) and 2.8 kg (hard-shell) when empty.

Before you leave, always check the dimensions allowed by your airline. Our cabin suitcase size guide by airline lists the dimensions for all major European carriers.

Short stay (4-7 days): the M week suitcase (65 cm, 65 L)

For 4 to 7 days, the M suitcase is the most versatile format. Its 65 liters allow you to pack a full week of clothing, shoes included, with room for return purchases. It goes in the hold with a standard 23 kg allowance without difficulty.

Its empty weight at GYL is 3.8 kg for hard-shell models and 2.9 kg for the soft-side version (Évasion M), which leaves you with 19.2 kg and 20.1 kg of useful content respectively on a 23 kg allowance. Find M models in our GYL week suitcase range, and check our article which suitcase size for 23 kg to optimize your allowance.

1 to 2 weeks: the L large suitcase (75 cm, 100 L)

The L suitcase is the standard for stays of one to two weeks. With 100 liters and a standard 23 kg checked baggage allowance, it covers all needs. The GYL Trunk L features this format with a vertical silhouette inspired by traditional travel trunks, made of 100% polycarbonate and covered by the worldwide warranty. See the GYL stay suitcase range for available options.

Long stay and family: the Trunk XL (80 cm, 115 L)

The Trunk XL is the suitcase for long trips and families sharing luggage. With 115 liters and a capacity of up to 28 kg, it is sized for stays of 3 weeks or more. Available in the GYL Trunk collection, it combines polycarbonate, 360° double wheels, and a worldwide warranty.

Essential Criteria for Choosing Your Suitcase

The worldwide warranty: the true quality criterion

A quality suitcase always comes with a serious warranty. All GYL suitcases are covered by a worldwide warranty: in the event of a manufacturing issue, parts (wheels, handles) are shipped within 48 hours, wherever you are in the world. It is the concrete sign of a long-term commitment, not a disposable product.

Traveling by Train: What You Need to Know

Trains impose their own constraints, often overlooked at the time of purchase. Unlike airplanes, there is no hold system: you manage your luggage yourself from A to Z.

Dimensions and rules on the train

On TGV and Intercités, the racks above seats generally accept cabin suitcases (approx. 55 x 40 x 20 cm). For large suitcases, spaces at the end of the carriage are limited, unsecured, and often crowded. Our article suitcases allowed on trains details SNCF and Eurostar rules according to the route.

Which format to choose for the train?

If you travel by train often, the S cabin suitcase is your best ally: it travels with you, stays under your control, and generates no fees. The 4-wheeled cabin suitcases with 360° double wheels are designed for this daily maneuverability. In narrow corridors, being able to push the suitcase sideways effortlessly makes all the difference.

How to Pack Your Suitcase Effectively

The best suitcase is useless if poorly packed. Here are the methods that truly save space.

The zone method

1. Lower zone (wheel side): shoes wrapped in bags, heavy and compact items. This stabilizes the suitcase when standing.
2. Central zone: clothes rolled rather than folded, for fewer wrinkles and more volume. Pants and jeans are rolled, shirts are folded flat.
3. Upper zone: light items, lingerie, accessories in separate pouches.

Weighing your suitcase before departure

A surprise at the airport scale is expensive: between 10 and 20 euros per excess kilogram depending on the airline. Remember to weigh your suitcase before leaving. A simple rule: aim for 21 kg for a 23 kg allowance; the 2 kg margin absorbs the imprecision of airport scales.

What never to put in checked luggage

Always keep in the cabin: medications, important documents, valuable electronic devices, jewelry, and lithium batteries. Lithium batteries are strictly prohibited in the hold by international air regulations. Consult the complete list in our article prohibited cabin luggage items.

FAQ: Travel Suitcase

What is the best travel suitcase?

The best travel suitcase is a hard-shell polycarbonate suitcase equipped with 4 multidirectional wheels, a TSA lock, and covered by a global warranty. This type of model offers the best protection for contents, proven durability, and optimal maneuverability in airports and train stations. The GYL range meets all these criteria, from the 55 cm carry-on size to the 80 cm Trunk XL.

How to choose your travel suitcase?

Ask yourself four questions: (1) How long is the trip? (2) Cabin or checked luggage, train, or car? (3) What is your baggage allowance? (4) What is your budget for durability? For the majority of travelers, a medium-sized hard-shell suitcase (65 cm, 65 L) made of polycarbonate or polypropylene covers 80% of situations.

What are the 5 best travel suitcases?

The best travel suitcases share the same characteristics: hard polycarbonate shell, silent spinner wheels, integrated TSA lock, aluminum telescopic handle, and global warranty. The GYL range offers several models meeting all these criteria, from the 55 cm carry-on size to the 80 cm Trunk XL.

What size suitcase for 23 kg?

A medium-sized suitcase (65 cm in height, 65 L capacity) allows you to reach 23 kg of contents with a comfortable margin. The empty weight is crucial: a hard-shell GYL model weighs 3.8 kg empty, leaving you with 19.2 kg of useful capacity. Soft-sided models (2.9 kg empty) offer an additional 0.9 kg.

How much does a 23 kg checked bag cost on Air France?

The cost of a 23 kg checked bag on Air France varies depending on the ticket and destination. With a Light or Classic Economy fare, it can cost between 30 and 80 euros per trip. It is always cheaper to book your luggage online at the time of booking than at the airport.

What size suitcase for train travel?

A carry-on suitcase (approx. 55 cm) is the recommended size for trains: it fits in the luggage racks above the seats and remains under your control. For long-distance journeys, a medium suitcase (65 cm) can be placed in the luggage areas at the end of the carriage. Avoid large suitcases on trains: space is limited and not secured.

How to pack your travel suitcase properly?

Roll clothes instead of folding them to save space. Pack shoes at the bottom to stabilize the suitcase. Use packing cubes to organize by category. Always keep your documents, medication, and electronic devices in your carry-on. Weigh your suitcase before leaving to avoid excess baggage fees.

Hard-shell or soft-sided suitcase: which is better?

A hard-shell suitcase is superior for regular use: better protection for belongings, waterproofing, integrated TSA lock, and easy maintenance. A soft-sided suitcase is suitable for occasional travelers who prioritize lightness. For more than 3 trips per year, a hard-shell suitcase is systematically recommended: the difference in durability over 3 to 5 years easily justifies the initial investment.
