Japan Blue 13.5oz "Sunny Knight" New Type 2 Denim Jacket

Size Guide
Inspired by vintage Levis jackets worn around the 1950s~, this iconic and timeless design is full of details borrowed from the past.

As one of JB's most popular denim for all year usage, this 13.5oz denim is woven using vintage machines. Thanks to the Cote d'Ivoire cotton, this denim comes with uneven textures and smooth touch, you will see a soft contrast appear with some beautiful bright hues of indigo shining out. The inner lining is also woven using vintage machines and skilfully printed with a classic Chimayo style 'God of Sun' pattern.

Unlike a typical type 2 jacket, this version comes with twin side pockets for extra practicality. For classic taste, this features riveted copper 'doughnut' style buttons. The chest pockets also include some contrasting lining. Use the backside adjusters to always get the right fit!

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.
