Polycarbonate is the best luggage shell material for most travellers: it absorbs impact by flexing and springing back, where ABS is more likely to crack. Polypropylene (PP) is a good budget choice, tough and light but prone to denting and flexing out of shape. ABS is the cheapest and the most brittle of the three, best kept for occasional trips.

Price ranges are typical Indian retail prices in October 2026 and vary with sales.

The three materials, in plain words

Polycarbonate (PC): best all-round

Polycarbonate is a tough, slightly flexible plastic also used for things like safety visors and machine guards. On a suitcase, that flexibility matters: when a bag is dropped or squeezed in an aircraft hold, a PC shell bends and returns to shape instead of cracking. It also handles heat and cold well, which helps on hot Indian tarmacs.

• Good: impact tolerance, light for its strength, holds its shape

• Watch for: scuffs on glossy finishes (cosmetic only), and listings that call an ABS blend "polycarbonate"

More on the material in what is polycarbonate luggage.

ABS: cheapest, most brittle

ABS is a rigid, inexpensive plastic. It keeps prices low and feels stiff in the hand, but that stiffness is the problem: under a sharp knock, especially at the corners, ABS is more likely to crack than flex.

• Good: low price, light, glossy finishes

• Watch for: cracks at corners and wheel housings after rough handling

Polypropylene (PP): tough budget option

PP is a lightweight, flexible plastic, usually injection-moulded into thicker shells. It resists surface scratches and takes knocks without cracking, but a soft PP shell can dent or bow, and very thin PP feels flimsy.

• Good: price, scratch resistance, impact tolerance for the cost

• Watch for: denting, shells that flex too much when packed full

Blends and films: read the label

Many budget bags use ABS + PC blends or an ABS shell with a thin PC film on top. The film helps with scratches, but the core behaves mostly like ABS. If a listing says "ABS+PC", "PC film" or just "hard case", it is not 100% polycarbonate.

The material is only half the story

Even the best shell can be damaged by a rough baggage handler. Two questions decide what happens next:

1. Does the warranty cover shell cracks? Many warranties cover "manufacturing defects" only. Look for shell, wheels, handle and zips named explicitly.

2. Is airline damage covered? Many luggage warranties exclude damage caused in transit, which is exactly when hard shells take their worst hits.

This is where WNTR's approach differs. Both WNTR lines use 100% polycarbonate, and every bag comes with 1 year of airline-damage protection included free, on top of the warranty: 10 years on Strunk™ and 5 years on Dawn X. Details are in the warranty policy, and the quality testing page shows how the shells are tested.

The verdict

Choose 100% polycarbonate if you fly often or check bags in; PP if you're on a budget or mostly travel by road; ABS only for rare trips. Then check what the warranty covers, including airline damage.
