How to Choose a Carry-On Bag: Hard-Side vs Soft-Side Luggage

Picking the right carry-on can make or break your travel day. You want something that fits in the overhead bin, rolls smoothly down narrow aisles, and holds everything you need without checking a bag. But with so many options, the biggest decision often comes down to one question: hard-side or soft-side?

Both styles have real strengths, and the right choice depends on how you pack, where you’re going, and what you value most. This carry-on bag buying guide breaks down the differences so you can choose with confidence—no guesswork required.

Hard-Side Luggage: What It Does Well

Hard-side suitcases are built with rigid shells made from materials like polycarbonate or ABS. Their biggest advantage is protection. If you’re carrying fragile items like electronics, cosmetics in glass bottles, or a souvenir you don’t want crushed, a hard shell keeps everything safe from impacts and pressure. It’s also more water-resistant than fabric, so a sudden downpour on the tarmac won't soak your clothes.

Hard-side luggage tends to last longer against scratches and scuffs compared to fabric, though a white or light-colored shell may show marks more quickly. They also offer a sleek, professional look that works well for business travel. The tradeoff is weight—hard shells can be heavier than soft bags, limiting how much you can pack before hitting airline weight limits.

• Great for fragile or valuable items
• More water-resistant than fabric
• Easier to wipe clean after a messy trip

Soft-Side Luggage: Flexibility and Function

Soft-side bags, typically made from nylon or polyester, are the classic choice for travelers who like to pack a little extra. The fabric walls give slightly, so you can overstuff a bit without worrying about the zipper bursting. Many soft-side carry-ons also come with exterior pockets, which are perfect for stashing a book, a snack, or your boarding pass for quick access.

Soft-side luggage is often lighter than hard-side, leaving more room in the weight allowance for your things. It’s also more forgiving if you’re squeezing it into a tight overhead bin. The downside is that fabric isn’t as protective against heavy drops or sharp objects, and without the right lining, it may not be fully waterproof. For commuters and weekend travelers, soft-side bags like the Landon Carryall in Onyx or the Dakota Backpack in Dark Moss offer a practical, flexible option that fits a variety of carry-on needs.

• Expands to fit last-minute items
• Exterior pockets for quick access
• Often lighter and easier to lift overhead

Size and Airline Restrictions: What Fits

Before you fall in love with a bag, measure it. Most domestic airlines require carry-ons to be under 22 x 14 x 9 inches, including wheels and handles. An expandable soft-side bag can stretch to that limit (or slightly beyond), so check the manufacturer’s dimensions carefully. Hard-side luggage usually has a fixed size, but some models meet the exact limits, leaving no room for error.

If you travel with budget airlines, you may need a smaller carry-on to fit their stricter size limits. A personal item like the Bennie Sling in Dune can complement your main carry-on, giving you a place for your phone, passport, and wallet while keeping the larger bag overhead. Always confirm the size and weight restrictions with your airline before booking, and remember that regional carriers often have different rules than international ones.

• Common domestic carry-on limit: 22 x 14 x 9 inches
• Measure including wheels and handles
• Budget airlines often require smaller dimensions

Packing Considerations: How You Travel Matters

Your packing style plays a big role in the hard-side vs soft-side decision. If you like to roll clothes and pack neatly in packing cubes, a hard-side bag with a flat interior works well. You can maximize space by organizing everything in layers. Hard-sided luggage also tends to have better internal dividers, so you can separate clean clothes from dirty ones or keep shoes away from your outfits.

If you prefer to toss things in and go, a soft-side bag with expandable compartments gives you more flexibility. The exterior pockets are a major perk for quick access to your boarding pass or a travel-sized umbrella. For business trips, consider a garment bag or a carry-on with a suit compartment. For active trips, a backpack-style carry-on like the Dakota Backpack offers comfort and hands-free convenience, especially when you’re navigating train stations or city streets.

• Packing cubes help both hard and soft shells
• Use exterior pockets for items you need during the flight
• Backpacks are easier to carry up stairs or on transit

Durability and Maintenance: Long-Term Value

Hard-side luggage wins on impact resistance, but it’s not indestructible. Polycarbonate can crack under extreme pressure, and some shells show cracks after rough handling. Soft-side luggage can tear or get punctured, but it’s often easier to repair—many brands offer zipper or strap replacements. For frequent flyers who check bags occasionally, a hard-side case offers peace of mind; for those who mostly carry on, a well-made soft-side bag may serve you just as well at a lower price.

To extend the life of your luggage, treat it well: wipe down hard shells with a damp cloth, spot-clean fabric bags, and lubricate zippers periodically. If you own a leather or nylon carry-on, follow the manufacturer’s care instructions. The Landon Carryall and Dakota Backpack are both designed to withstand regular use, but a little maintenance goes a long way in keeping them looking sharp.

• Hard shells: clean with a damp cloth
• Fabric bags: spot-clean and air dry
• Keep zippers running smoothly with a silicone lubricant

Making the Final Decision: Ask Yourself These Questions

Start with what you’ll carry. If you pack electronics, glass, or fragile gifts, a hard-side case offers better protection. If you tend to overpack or like having outside pockets, a soft-side bag is more forgiving. Consider your typical travel routine: do you fly weekly, or take a few trips a year? A frequent flyer might value weight and maneuverability over maximum protection.

Also think about where you’re going. For beach vacations, a soft-side bag with water-repellent fabric is practical. For city breaks or business trips, a hard-side case with a sleek look can feel more polished. If you regularly use public transit or walk to your hotel, a backpack carry-on like the Dakota Backpack reduces strain and keeps your hands free. Whatever you choose, make sure it fits your airline’s limits and matches your packing habits.

• What items do you carry most often?
• How often do you fly, and with which airlines?
• Do you prefer a polished look or outdoor practicality?

Choosing between hard-side and soft-side luggage comes down to your priorities: protection and water resistance versus flexibility and easy access. Measure your bag, check your airline’s rules, and think about how you actually like to pack. With the right carry-on, you’ll breeze through the airport and enjoy a more organized trip.
