What is hard-shell luggage?

Before we examine why most hard-shell luggage opens in the middle, let’s review the lingo. ‘Hardshell’ (A.K.A. hardside) refers to a type of luggage with a tough, rigid exterior.


This heavy-duty outer shell is made from sturdy materials like polycarbonate to protect against sudden downpours or impetuous baggage handlers. Hard-shell luggage is also stylish, easy to clean, highly manoeuvrable and can be stacked up neatly in a pile.


The alternative is ‘soft-sided’ luggage, which refers to a backpack, duffel, travel case or any other bag with a flexible exterior. This malleable outer layer lets the bag contort into tight, irregular-shaped spaces and stretch to provide extra storage space. See our post on hard-side versus soft-side luggage for more details.

Why does most hard-shell luggage open in the middle?

Almost all modern hard-shell suitcases adopt the clam-shell form, a design with a split straight down the centre to create two even storage spaces on each side. This 50-50 division offers many practical benefits.

  • Durability: The middle-opening layout reinforces the suitcase frame, making cracks and fractures less likely when venturing on bumpy terrain


  • Weight distribution: A centre split makes it easy to spread weight evenly across both sides of the suitcase, improving balance and manoeuvrability


  • Packing and unpacking: This inevitable travel chore becomes less tiresome with a convenient clam-shell suitcase offering direct access to two evenly-sized storage spaces  


  • Locating items: Instead of rummaging through a deep trunk, you can visually identify your required item from one of two shallow storage sections As manufacturing technology and materials evolved in the mid-20th century, the more practical clam-shell design began phasing out the classic trunk suitcase.

As manufacturing technology and materials evolved in the mid-20th century, the more practical clam-shell design began phasing out the classic trunk suitcase.


But it does have some downsides. Notably, the clamshell requires twice as much space to open as a trunk with a top lid.


Clam-shell luggage isn’t as convenient for transporting bulky or irregular-shaped items — think musical instruments or sporting equipment. Plus, certain discerning travellers have a passion for the vintage aesthetic of antiquated trunk suitcases.


So, while the clam-shell design rules the hard-side luggage roost, the timeless trunk won’t disappear anytime soon.
