lättvikt

Lättvikt is a Swedish term meaning lightweight, used to describe objects or categories with relatively low mass. It is used both as a general descriptor and as a technical term in sports, engineering, and product design. In everyday language it can refer to anything marketed as easy to carry or transport, such as laptops, bicycles, or luggage, and it often appears in compound forms like lättviktsdesign or lättviktsmaterial.

In sport, lättvikt denotes a weight class. The exact limits vary by sport and federation. In professional boxing, lättvikt describes the class up to about 61 kilograms (135 pounds), sitting between featherweight and welterweight. The term is similarly used in other combat sports to indicate a roughly comparable weight range, though the official limits differ.

In materials and engineering, lättvikt refers to low-density materials or designs that reduce overall mass while maintaining function. Common examples include aluminum alloys, carbon fiber reinforced polymers, and various foams and composites used in transport, aerospace, and sporting equipment. Lättviktskonstruktioner aim to improve performance, fuel efficiency, and handling, but can entail higher cost, manufacturing complexity, and trade-offs in durability or energy absorption.

Summary: Lättvikt is a broad term for light weight, applied across contexts from sports weight classes to materials science and consumer products. Its precise meaning depends on context and standards within a given field.
