Iron Heart 16oz 555S-SLB Denim (Slim Tapered Fit)

Size Guide
If you've been waiting for the IH's dip into the indigo ocean, this is the SPLASH you've been waiting for.

To unleash their SLUB to the world, IH specially developed this irregular textured 16oz denim. The once washed state makes up for a beautifully soft break-in and has revealed the strong vertical, slubbly texture. Looking closely you can see the extreme variation in the weave, with time you'll see some amazing high contrast fades. The raised slub will become the highlights and allow the crevices to remain dark and deep. Reminding us of the movie JAWS, the indigo waters are so choppy you'll never know when shark teeth will appear...

The front pocket bags are made up of a sturdy, 10oz unbleached, cotton twill fabric. For added durability, the rear back pockets are also lined with this cotton twill, meaning there's no need to worry about your wallet wearing through!

Constructed with extra heavy, cotton and poly threads, this makes up for an extremely durable pair. The leather patch is made up of extra-thick vegetable tanned cowhide and features a debossed design. With time this will age to a deep brown hue with a tasteful sheen.

For a textured slim tapered fit with a mid-rise, this is a great choice for you!

How We Measure

Pants and Shorts


With the major buttoned up (i.e. the top button) open the jeans and lay them flat, like shown. Measure from the front where the major button closes to the back belt loop. Double this measurement to find the waist measurement.

The way we measure the waist is different from the 'Side to Side' technique. If you are used to the 'side to side' technique you can roughly roughly downsize by 1 inch.

For example, 'side to side' measurement for The Flat Head 3002 waist is 28inch and using our method measures at 29.25inch.

Front Rise:

With the jeans lying flat measure from the crotch bar tack to the top of the waistband. 

Back Rise:

Spread out the crotch so the bar tack is visible, then measure from the crotch to the top of the waistband.


One inch down from the crotch, measure flat across to the other side.


Flatten the leg and measure along the inseam from the crotch to the leg hem. 

Leg Openning:

Measure straight across the hem from side to side.





Lay flat then measure from the shoulder's edge to the other shoulder's edge.


Lay shirt flat and measure from pit to pit.

Sleeve length:

With the sleeve flat measure from the shoulder to the cuff.

Arm hole openning:

Vertical length:

With the shirt facing down, Measure from below the collar to the bottom hem.
