BASISBROEK
BASISBROEK / Orgen Cotton Linen Shirt Jacket
BASISBROEK presents a lightweight layer that bridges the gap between a shirt and a jacket.
Based on a classic regular-collar shirt, it features side pockets that add jacket-like functionality. Easy to throw on over a T-shirt or another shirt, it strikes a natural balance—light, unforced, yet quietly refined.
Crafted from a breathable cotton-linen blend, it combines the softness of cotton with the airy coolness of linen for comfort even in warmer weather.
Effortless and understated, yet refined—this kind of in-between piece is exactly what defines a modern spring and summer wardrobe.

BASISBROEK
Founded in 2004 as a pants brand, the name means “basic pants” in Dutch. Using carefully selected fabrics in Japan, the brand expands from pants to shirts, coats, and more. By incorporating various design elements, focusing on silhouette and comfort, and applying finishes that highlight the qualities of the materials, BASISBROEK creates contemporary everyday wear that enhances the wearer’s individuality.


Cool comfort of cotton-linen blend
The fabric is a blend of 73% cotton, 24% linen, and 3% polyurethane.
Combining the dry, airy texture of linen with the softness of cotton, it achieves a well-balanced fabric. Added stretch enhances mobility beyond what the fabric’s appearance suggests.
With wear, gentle wrinkles develop, adding a rich, natural depth unique to natural fibers.

Subtle functional beauty in the pockets
The collar features a classic regular style.
Balanced in its opening, neither too tight nor too loose, it maintains a refined presence whether buttoned or open.
The front uses simple buttons, stripping away unnecessary details to highlight the fabric’s natural texture.


The standout feature of this model is the side pocket that extends from the front to the back. Acting as a visual accent, it also provides practical storage for a smartphone or small items, making it as functional as a jacket while maintaining a shirt’s form.
The hem is square-cut, keeping a balanced silhouette even without tucking in, and works well when layered.

Relaxed, yet not sloppy
A relaxed silhouette with generous width across the body. However, careful adjustment of the collar and length ensures it doesn’t appear too casual.
The boxy form pairs perfectly with contemporary styling. Matching with pants of the same fabric creates a cohesive set-up look.
Whether worn alone or layered, it always looks polished. Its charm lies in being effortless yet refined.
