Sk831 Heavy Marine 18oz.
The collection we are proud to present, the Sk831 HeavyMarine model, is inspired by the charming stories of the sailor. It comes with Okayama raw denim at 18oz, 100% cotton, Sanforized. The cotton yarn dyeing process has been developed in the classic Deep Indigo style, and this model gains its own distinct identity through details in various places, in the style of the Military Series.
The story of the sailors’ adventures in the year 1865 is told in a distinctive way on the lining of these jeans. On the left side is an image of the camaraderie of sailors who travel together and fight with courage, and on the right side is an image of a sailor waving a victory flag, symbolizing triumph and good fortune while out at sea.
Paired with Made in Japan donut buttons with an olive wreath in the WWII style, which carry the meaning of “peace,” and adding to the vintage feel with rust stains on the various buttons, as if they had been through the stories of a journey.

Need your jeans shorter or longer? We can hem them to your exact inseam, or make them in an extended length. Just add your preferred inseam length (inches or cm) in the Order Note at checkout.
Our jeans use vanity sizing, which means the tagged waist size does not correspond to your actual body or true waist measurement in inches. Measure a pair of non-stretch jeans that fits you well:
- Zip, button, and lay them flat
- Measure straight across the waist, then multiply by 2
Example: 18" flat = 36" actual waist → size 34
