FN-8005 – 18oz Selvedge Denim Jeans Regular Straight
The FN-8005 jeans by The Flat Head are a true statement of uncompromising denim quality. Made from extremely tightly woven 18 oz selvedge denim, this model belongs to the heavyweight series and is aimed at true denim enthusiasts who value substance, longevity, and strong character fades.
The fabric is produced on traditional shuttle looms in Japan and is characterized by its massive structure, high density, and slightly irregular surface. The use of thick yarn structures creates a denim with a distinct feel that breaks in slowly and develops spectacular high-contrast fades ("Rain Drop / Doshaburi Fading") over time.
The fit is a classic regular straight fit with a medium rise, based on one of Flat Head's most famous cuts. It offers a balanced silhouette with ample freedom of movement and a timeless look.
Typical for The Flat Head is the uncompromising craftsmanship:
hidden copper rivets, solid metal buttons, a cowhide leather patch, and reinforced details such as raised belt loops ensure maximum durability and authentic vintage character.
The jeans are one-wash, meaning minimal shrinkage is to be expected and they can be worn directly – the break-in, however, occurs slowly and rewards patience with a unique patina.
