Freewheelers 13.5oz Indigo Denim "Derrickman" Work Pants (Modern Straight fit)

Those iconic denim workwear pants, Freewheelers do it the best!

We've seen many work pants but none as truly rugged as this! As one of FW's most successful work pants, this "Derrickman" design is inspired by late 1920s denim work pants and Freewheelers does re-create every details to the next level!

This 13.5oz denim is soft to the touch and has a subtle neppy texture. The grand indigo dyed threads will guarantee some amazing, high contrast fading with use! Compared to typical vintage worker denim with lighter oz and fewer indigo shades, FW's have created much more durable denim with better ageing over time.

As one of the iconic aspects of these trousers, the twin front thigh pockets are easy to use without being awkward! The front shin to the lower thigh is also double layered for better protection and durability. With right leg pockets and back rise 'tool loops' so you can always keep that gear on you! The standard front and rear pockets feature unique, angular designs that are easy to use and tastefully unique.

With so many more vintage details yet to be mentioned, these trousers are truly an example of FW's genius for creating some of Japan's TOP workwear gears for modern life!

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:

Measure from the shoulder down to the pitt.

Vertical length:

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