The K25 is an authentic heritage fit, based on the very first Kuyichi jeans: the K100 from 2001. The silhouette is inspired by the early 20th-century waist overalls worn by American miners, ranchers and railroad workers.

The high-rise waist, relaxed top block and roomy straight leg give the K25 its characteristic, laid-back silhouette. At the back, the jeans feature an adjustable cinchback: an iconic pre-war detail from the era before belt loops became standard.

What began as functional workwear grew into a cultural icon. Western legends like John Wayne brought denim to the big screen, after which Marlon Brando and James Dean turned the high-waisted, straight-leg jeans into a symbol of freedom, individuality and rebellion in the 1950s.

For this anniversary edition, we chose 100% regenerative cotton selvedge denim, woven by Italian denim mill Candiani. The dry denim is produced using Candiani’s Indigo Juice® dyeing technique and Kitotex® technology. Together, these innovations give the fabric its deep indigo look and authentic denim character. The 14.25oz denim offers a substantial, durable feel true to its heritage roots.

The K25 brings the origins of denim together with an important chapter in our own history. A true classic, relaunched for 25 years of Kuyichi.

These jeans come in a beautiful laundry bag, part of this anniversary edition.

These men's straight fit jeans are made from 100% regenerative cotton.

Please note: be careful with white sneakers, as the jeans may bleed slightly when new. After washing, this should no longer be an issue.
