Attribute deep dive

We break down what drove each score so you can weigh trade-offs.

Quality Analysis 90/100

This denim is built for longevity, featuring a substantial 14oz weight and the added tensile strength of short-staple American cotton, which is specifically noted to enhance durability. Further reinforcing its quality are custom engraved buttons and rivets, ensuring hardware integrity even with daily wear.

Comfort Assessment 60/100

This denim is likely to be rigid and heavy, as it is made from 100% cotton, weighs 14oz, and is described as "raw selvedge denim" with no mention of stretch. However, the "washed and distressed" finish may offer a slightly softer, broken-in feel compared to completely unwashed raw denim.

Sustainability Impact Not Available

This garment lacks sufficient evidence to assess its sustainability, as the text only mentions material composition (100% cotton) and manufacturing location (Made in Japan) without any specific positive or negative environmental or ethical claims.

Crafted using short-staple American cotton, Japan Blue's Black Circle denim fabric is modeled after vintage fabrics dyed a deep sulfur black color. Originally a double black denim, this iteration comes washed and distressed to replicate the look and feel of a pair of well-worn denim. American short staple cotton gives the fabric a light slub texture with added tensile strength, allowing for a quicker and higher contrasting fade patterns. Woven on vintage shuttle looms, Japan Blue's Circle line is their reimagining of easy to wear classics designed for everyday wear. Equipped with a custom branded leather patch and signature Japan Blue details.
