Freewheelers "M-1938" Field Jacket (Olive)

Size Guide

The ultimate military jacket!

The Freewheelers' take on the classic M-38 field jacket truly sets the standard in classic military-style jackets. Perfect for layering with your favourite sweatshirt or simply a tee for the warmer months, this jacket has been redesigned by Freewheelers for a slightly slimmer, modern fitting while still retaining the charm of early to mid-20th century garment design!

The outer shell is constructed with Freewheelers specially developed midweight cotton chino fabric. Slowly woven with vintage machines, this has a slightly irregular texture that has been garment dyed. In time this will age to a soulful look with plenty of vintage character! The internal lining is constructed with cashmere-soft, tan-coloured cotton flannel. This provides heat retention and is so comfortable against the skin you'll never want to take it off!

Construction-wise, Freewheelers has pulled out all the stops! The military-style lapel collar can be styled three ways - suit jacket style, fully buttoned for the colder weather or with the collar popped! The front opening can be secured with a straight zip as well as urea buttons. The twin hand warmer pockets can be buttoned to secure your daily small items, while the sleeve openings and waist can be adjusted to get the perfect fit! The 3-dimensional pleated back pattern design allows for a comfortable full range of movement while keeping an elegant silhouette!

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.
