Vertical Striped Gradient: The shirt features a bold vertical stripe pattern in a "faded" or ombré style. The color palette transitions through shades of navy blue, charcoal grey, and earth tones, giving it a textured, multi-dimensional look.

Fabric Texture: It appears to be made from a heavyweight flannel or brushed wool-blend, often referred to as a "shacket" (shirt-jacket) due to its thickness and structured drape.

Style & Fit
Cut: It has a slim-to-regular fit that sits close to the body without being restrictive, making it ideal for layering over a basic tee as shown in the image.

Neckline: A standard point collar that maintains its shape, contributing to a polished casual look.

Front Detail: It features a full button-down front and dual chest flap pockets, which add to the utilitarian, workwear-inspired vibe.

Styling Tip
This piece is highly versatile. In the image, it’s styled for a "street-casual" look with a white crewneck tee, black distressed skinny jeans, and white minimalist sneakers. For a more rugged feel, you could swap the sneakers for leather boots and the white tee for a dark turtleneck.
