The M90 variant camouflage is the camouflage pattern used for the Swedish Armed Forces vehicles. The pattern consists of hard lined geometric shapes, aiming to create a camouflage pattern effective in the temperate forests and plains of Sweden. It is affectionately known among Swedish soldiers as lövhögen, or "the leaf pile." In addition to the standard pattern, which was designed with Swedish forests in mind, desert and winter variants were later developed. The M90 uniform pattern was introduced into active service in the late 1980s, and was adapted by the entire force by the late 1990s.
