Men's Japanese-Style Windbreaker Jacket, in detail
This Japanese windbreaker jacket is an oversized lightweight shell with relaxed volume through the body and sleeves, light enough for daily wear and the commute. It feels big and light. It reads Japanese-style through the oversized, slouchy cut and plain minimal shell, so it looks quiet instead of sporty. Clean zip front, patch pockets.
A windbreaker is the simplest wind layer there is, and an oversized cut makes it look intentional instead of sporty: the extra volume gives a modern, slightly slouchy silhouette over a hoodie or a knit, while the shell still does its basic job of keeping a cold wind off your chest. Big. Light.
Fit and sizing
Loose, oversized fit. Sizes run S to 2XL. The supplier suggests S for 160 to 164 cm and 45 to 55 kg, M for 164 to 170 cm and 55 to 65 kg, L for 170 to 180 cm and 65 to 75 kg, XL for 180 to 186 cm and 75 to 85 kg, and 2XL for 186 to 190 cm and 85 to 90 kg. Size down for a closer fit.
Fabric and care
100% polyester shell. Machine wash cold with similar colours. No bleach. Line dry or tumble dry low. Cool iron on the reverse if needed.
Colours
Black, khaki and gray.
How to wear it
Over a hoodie with wide trousers. Over a tee with cargo pants. Leave it open for the full oversized shape.
Good to know
Oversized jackets look best when the trousers have some volume too. With slim jeans, the proportions can feel top-heavy.
The patch pockets sit low and deep, a good place for hands on a cold walk.
Pairs well with the seven-pleat kendo hakama and the heavyweight cooling t-shirt. Also in the same family: the lightweight polyester jacket.
More layers sit in outerwear and jackets. Our technical fabrics care guide covers polyester shells.
Frequently asked questions
What is this windbreaker made of?
A 100% polyester shell.
What size should I order?
S for 160 to 164 cm up to 2XL for 186 to 190 cm. Size down for a closer fit.
What should I wear with it?
Trousers with some volume, like wide trousers or cargos, balance the oversized shape.
Does this men's windbreaker jacket come in black?
Yes. Black is one of three colors for the Men's Oversized Windbreaker Jacket, alongside Khaki and Gray. You can get it in sizes S through 2XL.
Besides black, what other colors does this windbreaker jacket come in?
Amaji's men's Japanese-style windbreaker comes in black, khaki and gray, all in the same oversized cut. Every color is listed in sizes S to 2XL.
Is a polyester windbreaker a better choice than a cotton jacket?
In general, polyester windbreakers are lighter and dry faster than cotton jackets, while cotton feels softer and breathes more. The fabric of Amaji's Japanese-style windbreaker is listed in the material details on this page. Because the cut is oversized, you can layer a hoodie or sweater under it whichever fabric you prefer.
How loose is this oversized jacket compared with a regular zip jacket?
It is cut oversized on purpose, so the body sits looser than a standard zip jacket and leaves room for a hoodie or sweater underneath. If you want a closer fit, think about going one size down. It comes in S to 2XL.
