Quality Analysis 90/100
This denim is built for longevity, featuring 14oz sanforized selvedge denim and tensile strength from short-staple American cotton, which promises robust wear and quicker, high-contrast fading. Further reinforcing its quality are custom engraved buttons and rivets, indicating attention to durable hardware.
Comfort Assessment 50/100
This denim is crafted from 100% cotton and features a heavyweight 14oz fabric, which suggests a rigid feel, though the "Aged Wash" process aims to replicate the look and feel of a well-worn pair.
