Quality Analysis 90/100
This denim is built for longevity, featuring a substantial 14oz Japanese selvedge denim construction and robust hardware like custom engraved buttons and rivets, ensuring it can withstand repeated wear and develop unique fade patterns over time. The use of a custom branded cowhide leather patch further signals a commitment to quality materials.
Comfort Assessment 70/100
This denim is likely to offer a neutral comfort experience, as the 100% cotton 14oz selvedge fabric is rigid and lacks stretch, but the "curved waistband" is a positive design feature intended to conform better around the waist.
Sustainability Impact Not Available
This garment lacks any explicit sustainability indicators, such as recycled materials or ethical certifications, making it impossible to grade its environmental or social impact.
