Dubble Works Tubular 'Chopped' S/S Sweatshirt (Sumi Black)

Size Guide

Let's go training!

As part of their most popular 'CHOPPED' series, Dubble Works brings us these super cool daily sweats for your journeys!

As a practical, cost-saving measure of the past, vintage training sweats featured 'cut off' style sleeves to make for better breathability. Dubble Works brings back this vision to a high standard. The side seams feature a curved pattern to make for a more relaxed, comfy fit and the ribbed collar and waistband sits snugly against the body to keep in some warmth.

Made using vintage tubular knitting machines, the fabric is super soft and has a subtle vertical texture that will develop into a vintage look with use.

The flat-seamed construction is durable for your daily use and makes for an extra comfy feeling against the skin. Perfect to wear on top of a tee or by itself.

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.
