Weight
How much of your luggage weighs.
Packing Efficiency
A smarter way to compare luggage
Packing Efficiency™
The best lightweight luggage is not simply the lightest.
It is the luggage that gives you the most packing space in relation to its weight.
The higher the litres-per-kilogram number, the more efficiently your luggage uses its weight.

Why it matters
Lightweight alone does not tell the whole story.
The best suitcase is not simply the one that weighs the least. It is the one that lets you pack the most while weighing the least. That is why Heys looks at both capacity and weight together.

The Heys design philosophy
Lightweight should never mean less room.
We engineer every curve, component and material to maximize usable packing capacity while minimizing unnecessary weight.
Heys Packing Efficiency™ is calculated by dividing stated luggage capacity in litres by empty luggage weight in kilograms. Expanded capacity is used where specifically indicated. Published product values may be rounded.
