Attribute deep dive

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

Quality Analysis 90/100

This denim boasts excellent durability indicators, starting with the substantial 12.5oz sanforized raw selvedge denim and the use of long staple African cotton, both of which contribute to a robust and long-lasting garment. Further reinforcing its quality are the custom engraved button and rivets, which suggest secure hardware built to withstand stress.

Comfort Assessment 60/100

The use of long staple African cotton suggests a premium, softer feel, but the 12.5oz raw selvedge denim is likely rigid and heavyweight, offering no stretch for movement.

Sustainability Impact Not Available

This garment lacks any explicit sustainability indicators, such as organic or recycled materials, making it impossible to grade its environmental or ethical impact based solely on the provided text.
