Hard-shell or Soft-shell Suitcase: Which to Choose?
This is the first question to answer. The two technologies meet different needs, and making the wrong choice will cost you on every trip.
Advantages of hard-shell luggage
Hard-shell luggage protects its contents much better. In the event of an impact on a baggage carousel or rough handling in the hold, the shell absorbs impacts without your belongings suffering. Other strengths:
- 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 maintained even when fully loaded
- 360° double wheels: smooth maneuverability in airports and train stations
For regular use, i.e., more than 3 trips a year, a hard-shell suitcase is the only rational choice. Consult our hard-shell or soft-shell suitcase guide to delve deeper into the comparison.
The GYL hard-shell range
From cabin 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.
View hard-shell suitcasesAdvantages of soft-shell luggage
Soft-shell luggage offers slight flexibility to slip in a last-minute purchase. Lighter when empty for some models, it is suitable for occasional travelers who prioritize capacity over protection. GYL's Évasion collection in waterproof polyurethane represents the best soft-shell luggage can offer: lightweight (2.2 kg carry-on), resistant, with 360° double wheels, and covered by the 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 | Impact 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 | Adequate, can crack under strong impact | Heavier | Limited lifespan | Not offered |
Polycarbonate: the choice for regular travelers
Polycarbonate is the benchmark material for high-end suitcases. Unlike ABS, which can crack under a violent impact, polycarbonate deforms slightly and then returns to its original shape: this is known as shape memory. GYL's Intemporelle and Trunk collections are made of 100% high-density polycarbonate: lightweight, scratch-resistant, and covered by the global warranty.
Polypropylene: strong and affordable
Polypropylene offers excellent rigidity at a more accessible price. It resists deformation well and is perfectly suited for travelers who go away 2 to 4 times a year. GYL's Citadine and Signature collections use this material with the same demanding finish and the same global warranty.
ABS: to be avoided for regular use
ABS is the material 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 a good investment. Our complete guide to rigid luggage materials details the technical differences to help you choose.
What Size Travel Suitcase Should You Choose?
Trip duration is the most reliable criterion for choosing the right size. Here are concrete benchmarks based on the actual capacities of GYL suitcases.
Weekend (2-3 days): Cabin Suitcase S (55 cm, 35 L)
For a weekend, the Cabin Suitcase S is sufficient and optimal: it travels in the cabin with you, avoids waiting for luggage, and saves on checked baggage fees. With 35 liters, it holds 3 to 4 outfits, a toiletry bag, and a laptop. GYL S-sized models weigh between 2.2 kg (soft Évasion) and 2.8 kg (hard-shell) empty.
Before you go, always check the dimensions allowed by your airline. Our guide to cabin luggage sizes by airline lists the dimensions of all major European airlines.
GYL Cabin Suitcases
35 L · airline-compliant sizes · global warranty · from 2.2 kg empty
Short stay (4-7 days): Week Suitcase M (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's worth of clothes, including shoes, with room for return purchases. It can be checked as standard 23 kg luggage without difficulty.
Its empty weight at GYL is 3.8 kg for rigid models and 2.9 kg for soft models (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 suitcase range, and consult our article what size suitcase for 23 kg to optimize your allowance.
1 to 2 weeks: Large Suitcase L (75 cm, 100 L)
The L suitcase is the benchmark 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 takes this format with a vertical silhouette inspired by traditional travel trunks, made of 100% polycarbonate and covered by the global warranty. Consult the GYL travel suitcase range for available options.
Long stay and family: Trunk XL (80 cm, 115 L)
The Trunk XL is the suitcase for long journeys and families who share 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 Trunk GYL collection, it combines polycarbonate, 360° double wheels, and a global warranty.

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

The 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.
Train Travel Suitcase: What You Need to Know
Train travel imposes its own constraints, often overlooked at the time of purchase. Unlike airplanes, 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 generally accept cabin suitcases (approximately 55 x 40 x 20 cm). For larger suitcases, spaces at the end of the carriage are limited, unsecured, and often quickly taken. Our article suitcases allowed on the train details SNCF and Eurostar rules depending on the route.
Which format to choose for the train?
If you travel frequently by train, the Cabin Suitcase S is your best ally: it travels with you, remains under your control, and incurs no fees. GYL cabin suitcases with 4 double 360° 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 and Organize Your Travel Suitcase Efficiently
The best suitcase is useless if poorly packed. Here are the methods that truly save space.
The zone method
- Bottom zone (wheel side): shoes wrapped in bags, heavy and compact items. This stabilizes the upright suitcase.
- Central zone: clothes rolled rather than folded, for fewer creases 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
The surprise on the scale at the airport is expensive: between 10 and 20 euros per excess kilo depending on the airlines. Remember to weigh your suitcase before leaving. Simple rule: aim for 21 kg for a 23 kg allowance; the 2 kg margin absorbs airport scale inaccuracies.
What you should never put in checked baggage
Always keep in your carry-on: medications, important documents, valuable electronic devices, jewelry, and lithium batteries. Lithium batteries are strictly prohibited in checked baggage by international air regulations. Consult the complete list in our article prohibited items 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 cabin size to the 80 cm Trunk XL.
How to choose your travel suitcase?
Ask yourself four questions: (1) How long is the trip? (2) Plane in cabin 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 height, 65 L capacity) 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 polycarbonate casing, 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 cabin size to the 80 cm Trunk XL.
What size suitcase for 23 kg?
A medium-sized suitcase (65 cm height, 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, leaving you with 19.2 kg of usable content. Soft models (2.9 kg empty) offer an additional 0.9 kg.
How much does a 23 kg checked bag cost on Air France?
The price of a 23 kg checked bag 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 luggage online at the time of reservation than at the airport.
What size suitcase for train travel?
The carry-on suitcase (approx. 55 cm) is the recommended size for train travel: it fits into the overhead compartments above the seats and remains under your control. For long-distance journeys, a medium 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. Place 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 you leave to avoid excess baggage fees.
Hard-sided or soft-sided suitcase: which is better?
A hard-sided suitcase is superior for regular use: better protection for belongings, waterproofing, integrated TSA lock, easy maintenance. A soft-sided suitcase is suitable for occasional travelers who prioritize lightness. For more than 3 trips per year, a hard-sided suitcase is systematically recommended: the difference in durability over 3 to 5 years largely justifies the initial investment.
