The IH‑666D is Iron Heart’s first non-denim 5-pocket jean, rendered in a heavyweight 17 oz brown cotton duck canvas that’s tightly woven, tough, and unapologetically rugged. Unlike softer selvedge denim, this duck fabric breaks in slowly, developing chalky fades and polish over time. Designed with a low-to-mid rise and slim-straight leg, the 666 silhouette offers a classic fit with enough structure to hold shape through most activities. Details include a sturdy button fly, lined rear pockets, hidden rivets, reinforced pocket openings, and poly/cotton constructional stitching throughout. The canvas is sanforized and pre-washed, which means size stability with minimal stretching expected in the waist. 100% cotton duck canvas 17 oz heavyweight plain weave fabric Slim-straight cut, low-mid rise Sanforized and one-washed—minimal shrinkage Button fly with branded waistband tack button Lined rear pockets with hidden rivets Reinforced front pocket openings with tape Heavy-duty poly/cotton stitching (single and chain-stitched) Belt loops sewn into the waistband Made in Japan table { width: 100%; border-collapse: collapse; } th, td { border: 1px solid black; padding: 8px; text-align: center; } th { background-color: #f2f2f2; } Size Waist Front Rise Back Rise Thigh Knee Hem Inseam 28 27.5 9.8 14.7 10.7 7.9 7.4 36.5 29 28.8 10.0 14.8 10.8 8.0 7.5 36.5 30 29.5 10.2 14.9 11.2 8.4 8.0 36.5 31 29.8 10.3 15.2 11.4 8.5 8.1 36.5 32 31.1 10.6 15.6 12.0 8.7 8.2 36.5 33 32.3 11.4 15.7 12.1 8.8 8.3 36.8 34 33.6 11.5 16.0 12.5 8.9 8.4 37.0 35 34.2 11.6 16.1 12.8 9.1 8.5 37.0 36 35.0 11.9 16.3 12.7 9.4 8.8 37.0 38 37.0 12.0 16.7 13.4 9.7 9.2 37.0 40 40.2 12.1 16.9 14.4 10.1 9.7 37.0 42 41.1 12.3 17.0 15.0 10.6 10.1 37.0 44 43.0 12.4 17.1 15.2 10.7 10.2 37.0 A variance of +/-.5" is to be expected. Fit Notes: Shop owner Tommy is wearing a size 34 in these. That is pretty much his standard size from Iron Heart these days. These are especially stiff and hard to break in, so the more room, the better. The 666 has a bit of extra room in the leg, so it's easier than some of the trimmer kits. We highly recommend you size up in these. Tommy is 5'10", 162lbs with between a 33-34" true waist. *The 666 fit from Iron Heart is a modern slim straight cut with a medium rise, trim top block, and a gentle taper from the knee down for a clean, streamlined silhouette.*
