Hard-Shell or Soft-Sided Suitcase: Which to Choose?
This is the first question to decide. Both technologies meet different needs, and the wrong choice will cost you on every trip.
Advantages of a hard-shell suitcase
A hard-shell suitcase protects its contents far better. In case of impact on a baggage 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
- Easy maintenance: a quick wipe with a sponge is enough
- Structure maintained even when fully loaded
- 360° double wheels: smooth maneuverability in airports and train stations
For regular use, meaning more than 3 trips per year, a hard-shell suitcase is the only rational choice. Consult our hard-shell or soft-sided suitcase guide for a more in-depth comparison.
The GYL hard-shell range
From carry-on size to Trunk XL, in polycarbonate or polypropylene: all our hard-shell suitcases are covered by the GYL global warranty, with wheels replaced within 48 hours anywhere in the world.
See hard-shell suitcasesAdvantages of a soft-sided suitcase
A soft-sided suitcase offers slight flexibility to slip in a last-minute purchase. Lighter when empty for some models, it suits occasional travelers who prioritize capacity over protection. The GYL Évasion collection in waterproof polyurethane represents the best a soft-sided suitcase can offer: lightweight (2.2 kg carry-on), durable, equipped with 360° double wheels, and covered by a global warranty.
Its limitations: it absorbs moisture on low-end textile shells, deforms over time, and provides 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 luggage market, with major differences in strength and longevity.
| Material | Shock Resistance | Weight | Durability | GYL Collections |
|---|---|---|---|---|
| Polycarbonate | Excellent, absorbs without cracking | Very lightweight | Very long-lasting | Intemporelle, Trunk L, Trunk XL |
| Polypropylene | Good, resists deformation well | Lightweight | Durable over time | Citadine, Signature |
| ABS | Fair, can crack under strong impact | Heavier | Limited lifespan | Not offered |
Polycarbonate: the choice for frequent travelers
Polycarbonate is the benchmark material for high-end suitcases. Unlike ABS, which can crack under a violent impact, polycarbonate deforms slightly and then regains its shape: this is known as shape memory. The Intemporelle and Trunk GYL collections are made of 100% high-density polycarbonate: lightweight, scratch-resistant, and covered by a global warranty.
Polypropylene: sturdy and affordable
Polypropylene offers excellent rigidity at a more accessible price. It resists deformation well and is perfectly suited for travelers who go on trips 2 to 4 times a year. The Citadine and Signature GYL collections use this material with the same finishing standards and the same global warranty.
ABS: to be avoided for regular use
ABS is the material used for entry-level suitcases. Heavier and more fragile, it can crack under a strong impact in the hold. If you travel more than twice a year, ABS is not the right investment. Our complete guide to rigid suitcase materials details the technical differences to help you choose.
What Size Travel Suitcase Should You Choose?
The duration of the trip is the most reliable criterion for choosing the right size. Here are the concrete benchmarks based on the actual capacities of GYL suitcases.
Weekend (2-3 days): the S carry-on suitcase (55 cm, 35 L)
For a weekend, the S carry-on suitcase is sufficient and optimal: it goes in the cabin with you, avoids waiting for luggage, and saves on checked bag fees. With 35 liters, it holds 3 to 4 outfits, a toiletry bag, and a laptop. GYL models in size S weigh between 2.2 kg (soft-sided Évasion) and 2.8 kg (hard-shell) when empty.
Before you leave, always check the dimensions allowed by your airline. Our carry-on suitcase size guide by airline lists the dimensions for all major European airlines.

Short trip (4-7 days): the M week-long suitcase (65 cm, 65 L)
For 4 to 7 days, the M suitcase is the most versatile format. Its 65 liters allow you to carry a full week's worth of clothes, including shoes, with room for return purchases. It can be checked in with a standard 23 kg allowance without difficulty.
Its empty weight at GYL is 3.8 kg for hard-shells and 2.9 kg for soft-sided (Évasion M), which leaves you with 19.2 kg and 20.1 kg of usable content respectively on a 23 kg allowance. Find M models in our GYL week-long suitcases range, and consult our article what size suitcase for 23 kg to optimize your allowance.
1 to 2 weeks: the large L suitcase (75 cm, 100 L)
The L suitcase is the reference 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 uses this format with a vertical silhouette inspired by traditional travel trunks, made of 100% polycarbonate and covered by a global warranty. Consult the GYL travel suitcases range for available options.
Long stay and family: the Trunk XL (80 cm, 115 L)
The Trunk XL is the suitcase for long journeys and families who combine their 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 global warranty.

| Criterion | What to check | Why it's important |
|---|---|---|

Global warranty: the true criterion of quality
A quality suitcase always comes with a serious warranty. All GYL suitcases are covered by a global warranty: in case of a manufacturing defect, parts (wheels, handles) are shipped within 48 hours, wherever you are in the world. This is a concrete sign of a long-term commitment, not a disposable product.
Travel Suitcase for Train: What You Need to Know
Train travel has its own constraints, often overlooked at the time of purchase. Unlike planes, there is no baggage hold system: you manage your luggage yourself from start to finish.
Dimensions and rules on the train
On TGV and Intercités trains, overhead compartments usually accept carry-on suitcases (approx. 55 x 40 x 20 cm). For large suitcases, spaces at the end of the car are limited, unsecured, and often quickly taken. Our article suitcases allowed on the train details SNCF and Eurostar rules depending on the journey.
Which format to choose for the train?
If you travel frequently by train, the S carry-on suitcase is your best ally: it goes with you, stays under your control, and incurs no fees. The GYL carry-on suitcases with 4 double 360° wheels are designed for this daily maneuverability. In narrow corridors, being able to effortlessly push the suitcase sideways makes all the difference.
How to Pack and Organize Your Travel Suitcase Effectively
The best suitcase is useless if poorly packed. Here are the methods that truly save space.
The zone method
- Bottom zone (wheel side): shoes packed in bags, heavy and compact items. This stabilizes the suitcase when standing.
- Middle zone: clothes rolled rather than folded, for fewer wrinkles and more volume. Pants and jeans are rolled, shirts are folded flat.
- Top zone: light items, lingerie, accessories in separate pouches.
To go further, consult our guide what to pack in your suitcase for 1 week, with the complete list according to the season and destination.
Weigh your suitcase before departure
A surprise on the scale at the airport is expensive: between 10 and 20 euros per excess kilo depending on the airline. Remember to weigh your suitcase before leaving. Simple rule: aim for 21 kg for a 23 kg allowance; the 2 kg margin accounts for airport scale inaccuracies.
What you should never check in
Always keep in your carry-on: medication, important documents, valuable electronic devices, jewelry, and lithium batteries. Lithium batteries are strictly prohibited in checked luggage by international air regulations. Consult the complete list in our article items prohibited in carry-on baggage.
FAQ: Travel Suitcase
What is the best travel suitcase?
The best travel suitcase is a hard-shell polycarbonate suitcase equipped with 4 multi-directional wheels, a TSA lock, and covered by a global warranty. This type of model offers the best content protection, proven durability, and optimal maneuverability in airports and train stations. The GYL range meets all these criteria, from the 55 cm carry-on to the 80 cm Trunk XL.
How to choose your travel suitcase?
Ask yourself four questions: (1) How long is the trip? (2) Plane (carry-on or checked), train, or car? (3) What is the baggage allowance weight? (4) What budget for what durability? For most 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-shell made of polycarbonate, silent spinner wheels, integrated TSA lock, aluminum telescopic handle, and worldwide warranty. The GYL range offers several models that meet all these criteria, from the 55 cm cabin size to the 80 cm XL Trunk.
What size suitcase for 23 kg?
A medium-sized suitcase (65 cm high, 65 L capacity) allows you to reach 23 kg of content with a comfortable margin. The empty weight is crucial: a GYL hard-shell model weighs 3.8 kg empty, which leaves you with 19.2 kg of usable content. Soft-sided models (2.9 kg empty) offer an additional 0.9 kg.
How much does a 23 kg checked baggage cost on Air France?
The price of a 23 kg checked baggage on Air France varies depending on the ticket and destination. In Light or Classic Economy fares, it can cost between 30 and 80 euros per trip. It is always cheaper to book your baggage online at the time of reservation than at the airport.
What size suitcase for train travel?
A cabin suitcase (around 55 cm) is the recommended size for train travel: it fits in the overhead compartments and remains under your control. For long-distance journeys, a medium-sized suitcase (65 cm) can be placed in the spaces at the end of the carriage. Avoid large suitcases on trains: spaces are limited and not secure.
How to pack your travel suitcase well?
Roll clothes instead of folding them to save space. Store shoes at the bottom to stabilize the suitcase. Use packing cubes to compartmentalize by category. Always keep your documents, medications, 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 of belongings, waterproof, integrated TSA lock, easy maintenance. The 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 largely justifies the initial investment.
