Quality Analysis 90/100
This denim is built for the long haul, featuring a substantial 14oz sanforized Japanese selvedge denim that promises excellent abrasion resistance and structure. Further enhancing its longevity are the custom engraved button and rivets, which secure critical stress points, and the durable cowhide leather patch.
Comfort Assessment 60/100
This denim is likely to be rigid and restrictive due to the 14oz weight, 100% cotton composition, and lack of any stretch claims, though the "curved waistband" may offer a slightly better fit around the waist.
Sustainability Impact Not Available
This garment lacks specific sustainability indicators, such as certified organic or recycled materials, making it impossible to assign a sustainability grade based on the provided text alone.
