What is Skull Jeans?

Skull Jeans is a denim label from Japan created by FabFour, a Japanese clothing and accessories company. The label has a long standing following among denim enthusiasts, who have documented its jeans in forums and fade reviews.

Products and positioning

Skull Jeans focuses on simple, well made denim pieces rather than fashion statements. The range covers:

  • Jeans, including the 5010xx in a slim tapered cut
  • Chambray shirts with leather accents
  • A 14.5 oz reversible denim jacket

A distinctive feature is the use of Pima cotton. The 5010xx is made from 14.5 oz denim with a 6x6 Pima cotton construction, which the brand counts as the second lightest weave it uses. This choice of fibre sets the label apart from denim brands that rely on standard cotton.

Distribution

Skull Jeans is sold through denim specialist retailers such as Blue In Green in New York and through FabFour's own online shop.

Why it matters

Skull Jeans is part of the Japanese denim scene that built an international reputation through fabric experimentation and enthusiast communities, where long term wear and fading are documented and shared.
