Welcome to chapter One of our new ‘Story Series' with Momotaro Jeans!

Back to history! Momotaro (aka Peach boy) was born to be a warrior to defeat the ONI Demon with the help of his allies. This is where the ‘GOING TO BATTLE’ concept comes from. The ONI DEMON controls his ISLAND, from the wind, the sand to the volcanoes.

This one features the face of ONI incorporated into a minimal pattern with the Kanji Characters ”惡魔暴統集結” translating to ‘Violent Demon Squad’. You can also see the ONI-ISLAND volcano smoke circling around the border.

Wrap it round ya neck for a ‘GOING TO BATTLE’ style!

Thanks to the discharge printing method, with time the fabric will age up to a vintage look with some soft contrast.

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.
