Abstract
Compression bandage for use as the only bandage in a single-bandage system for compression therapy, comprising an elastic compression layer and an elastic comfort layer, of which at least 50% is permanently attached to the compression layer. The compression bandage has a full-stretch elongation (FSE) of between 25% and 60% beyond its unstretched length. Full-stretch elongation is defined as the elongation at which the second derivative (130) of a curve (110) showing tensioning force over longitudinal elongation has its global maximum (140).

A compression single-bandage comprising:
- a) an elastic compression layer having two opposed major surfaces;
- and
- b) an elastic comfort layer having a major surface, of which at least 50% is permanently attached to a major surface of the compression layer;
- wherein the compression single-bandage has a full-stretch elongation (FSE) of between 25% and 60% beyond its unstretched length, with full-stretch elongation being defined as the elongation at which the second derivative of a curve showing tensioning force over longitudinal elongation has its global maximum.
