Our Jeans Families

We have a number of different cuts of jeans, described below, many of which are available in various different denims and canvases. In a perfect world, all varieties of jeans in a particular cut would measure exactly the same, however because fabrics behave differently when being sewn and washed, there is variance between jeans made from different fabrics in the same cut. Please pay close attention to the sizing charts published on each of the product web pages for guideline measurements for that specific model.

Our Jeans are made by human beings

Which does mean that there are often small variations in size from the published measurement table and between jeans of the same model number and tag size. If any particular measurement is very important to you, please drop us an email or make a note in your order.

The 634 and 666 Cuts

634 Cut
Any jean with the 634 model number. This is where it all started for Iron Heart and we consider the 634 to be our 'signature' cut. Loosely based on a 1966 Levi's 501, it is a straight cut jean with a medium rise and slight taper from knee to hem.

666 Cut
Any jean with the 666 model number. This is a slim straight cut jean, a little slimmer all the way through the profile than the 634, but with a similar rise. We call this a 'grown up slim cut' and the original IH-666S (18oz Raw Denim) is nicknamed "the Devil's Fit".

The 555 and 777 Cuts

555 Cut
Any jean with 555 in the model number. These jeans are a high rise slim jean. They have a higher rise than the 634 and are quite a lot slimmer all the way through the profile. They look great on larger people who want a slim look below the knee.

777 Cut
Any jean with 777 in the model number. This is a slim cut jean with a lowish (but not silly low) rise. There is much more taper from the knee to the cuff, giving a very flattering, modern, slim silhouette. Looks great on most body types and also women/girls.

The 888 and 1955 Cuts

888 Cut
Any jean with 888 in the model number. This is a higher rise (between 634 and 1955) cut, with wide thighs, and taper from the knee to the cuff, giving a very relaxed yet flattering silhouette.

1955 Cut
Any jean with 1955 in the model number. This is our most traditional jean, and is an interpretation of the 1955 Levi’s 501. It has high rise, generous thighs and quite a lot of taper below the knee. Looks amazing on tall people and a great option if you have larger thighs. 

The 461 and 463 Cuts

461 Cut
Any jean with 461 in the model number. This a is a boot cut jean. Our boot cuts have a relatively low rise and a relatively small hem. We create the boot cut shape by tapering in at the knee rather than flaring out at the hem, so these are very slim through the thigh/knee.

463 Cut
Any jean with 463 in the model number. Designed by Haraki San for himself 7 years ago, to wear with sneakers, also known as "The Boss Cut". A slight bootcut with curve on the inseam so that it retains the selvedge on the outseam.
