Men's Slim-Straight Jeans.

Fit: They appear to be a slim-straight cut. They are tailored through the thigh and knee but maintain a consistent width down to the ankle, preventing them from being as tight as skinny jeans.
Rise: These have a mid-to-high rise, sitting comfortably at the natural waistline.
Wash: A medium-dark indigo wash with subtle "whiskering" (faded lines) near the hip and light fading along the thighs for a lived-in, authentic look.
Key Details
Hardware: Features a standard metal shank button and a zip-fly closure.
Stitching: Contrast amber/tobacco stitching, which is traditional for high-quality denim.
Fabric: The texture suggests a mid-weight denim, likely a blend of cotton with a small percentage of elastane (stretch) for mobility and comfort.
Style: The clean lines and classic five-pocket styling make them easy to pair with white sneakers (as shown) or leather boots.
Styling Recommendation
These jeans are a "wardrobe staple." To lean into a modern aesthetic, you can pair them with:
A crisp white t-shirt or a tucked-in linen shirt.
Minimalist leather sneakers or loafers.
A leather belt that matches your footwear.
