Quality Analysis 90/100
This denim is built for the long haul, featuring a substantial 13.5oz original selvedge denim woven in Okayama, Japan, which provides excellent material strength. Further enhancing longevity are the heavy flannel pocket bags and the custom shrunken-grain cowhide leather patch, both indicators of premium, durable components.
Comfort Assessment 50/100
This denim is likely to feel rigid and heavy due to the 13.5oz weight, heavy slub texture, and rigid hand-feel, which are characteristics of the 100% cotton, non-stretch fabric. However, the inclusion of soft flannel pocket bags offers a small positive touch against the skin.

Garment details
Need-to-know info pulled from the retailer’s description, sizing notes, and care callouts.
The 421SW denim from Pherrow's is sewn using the brand's original 13.5oz selvedge denim and features an array of details paying homage to the brand's roots in American reproduction. Woven in Okayama, Japan exclusively for Pherrow's, the 13.5oz yellow-line selvedge feature a heavy slub texture, deep indigo color, and rigid hand-feel similar to denim from the '40s. The jeans come sewn with heavy flannel pocket bags and mismatched buttons as a nod to WWII-period denim where materials for production were scarce. Rinsed for more convenient sizing, the denim features a shrunken-grain cowhide patch, time-accurate stitching specifications, and custom Pherrow's detailing on the interior. Cut in Pherrow's Classic Straight fit; a traditional straight silhouette.
