A belt-loop stitched to a waistband, for extra strength.

Like the mighty Iron Heart IH-634S, they’re based on the 1955 Levi’s cut, though probably not too closely, as Levi’s sued Iron Heart and other Japanese repro brands last year for trademark infringement. Unlike the IH-634S, which is made of incredibly hefty 21oz selvedge denim, the TWHR01 comes in a relatively lightweight 13oz selvedge, though it’s woven on the same 30” Riki-Shokki—that’s Japanese for “power loom”—and from the same long-fibre cotton.

Some more nerdy details:

• Goatskin leather patch
• Hidden rivets
• Donut buttons
• Button fly
• Selvedge detailing inside the watch pocket and the fly construction of the jeans
• Two colour stitching throughout
• Extra-heavy twill pocket bags
• Half-lined rear pockets
• Belt loops stitched into waistband for extra strength

And if you order now, you can get an optional crotch rivet free of charge. Yes, you read that right, an optional crotch rivet!
