Boncoura Type 3 Suede Cowhide Jacket

Size Guide
As new contenders in the 'heirloom standard' leather jacket game, Boncoura has brought some serious heat with their Cowhide Suede Type 3 Jacket!

Conventional wisdom says that vegetable tanning is the method of choice for premium leather products. However, in Japan, many different tanning methods are utilized to impart different qualities in the leather, including vegetable tanning, chrome tanning, oil tanning and salt tanning etc. Morishima-San, the boss and creative visionary of Boncoura believes that by using a combination of tanning methods, Boncoura can create luxury leather products that are sure to mature and develop into even more beautiful garments that you can wear and age for many decades!

The tanning process for this suede jacket uses a multi-method process. First, the leather is vegetable tanned then chrome-tanned, while the final step involves a secret process known only to the brand!
Premium rawhide leathers are selected and preserved with minimal dyeing to showcase the natural beauty and imperfections of the hide!
The final result combines an outer texture that resembles thick roughout leather, while the inner's texture looks and feels like premium deerskin!

For extra water resistance, a special water-proofing liquid is applied during the tanning process to reduce natural discolouration to the leather from water damage and general wear!

The fitting replicates Boncoura's denim type 3 denim, with an elegant slim-fitting silhouette!

Want more details? For Boncoura every detail counts, and you can see they have selected longer fibre hides for the side and inner panels, with smoother short-fibre hides for the front panels, to create a subtle tonal perfect look!

The brass snap buttons are hand-engraved and get oxidised. With time, the raised areas will become shinier and develop a beautiful patina!

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.
