Fabric & Design

Soft Cotton-Nylon Blend

These trousers are crafted from a carefully balanced combination of 65% cotton and 35% nylon, designed to provide everyday comfort with reliable durability.

The high cotton content offers a naturally soft and comfortable feel, making the trousers pleasant to wear throughout the day.

Nylon contributes additional strength and resistance to everyday abrasion while helping the fabric maintain its structure.

Together, these fibers create a balanced material that combines the familiar comfort of cotton with the practical advantages of nylon.

The fabric offers a naturally relaxed appearance without sacrificing the clean silhouette of the trousers.

Fabric Characteristics

Soft / Comfortable / Durable / Naturally Draped / Easy to Style

Garment-Washed Fabric

The trousers undergo a garment-washing process that softens the fabric and creates a subtle lived-in appearance.

This finishing treatment reduces the stiffness commonly associated with structured woven fabrics, providing a more comfortable wearing experience.

The washed texture enhances the fabric's natural drape, allowing the trousers to fall smoothly along the legs.

The resulting finish introduces a subtle vintage character while maintaining a clean, contemporary aesthetic.

This balance of softness and structure makes the trousers suitable for both relaxed casual outfits and more refined everyday styling.

Relaxed Straight-Leg Silhouette

Designed with comfort and versatility in mind, these trousers feature a relaxed straight-leg silhouette that provides generous room through the hips and thighs.

The straight-leg construction creates a naturally balanced shape from the upper leg to the hem.

Rather than following the body's contours closely, the relaxed cut allows the fabric to drape comfortably, creating an effortless appearance.

The silhouette accommodates different body types while maintaining clean proportions.

This versatile design pairs naturally with oversized shirts, casual jackets, structured outerwear, and contemporary knitwear.

Double-Pleated Waist Design

One of the defining features of these trousers is the double-pleat construction at the waist.

The carefully arranged pleats create additional volume around the waist and upper thigh area, allowing greater freedom of movement.

The pleated details also introduce subtle visual depth, giving the trousers a more refined appearance.

Inspired by traditional tailored trousers, the double-pleat design combines classic menswear elements with the relaxed proportions of contemporary Japanese fashion.

The result is a comfortable silhouette that balances casual practicality with understated sophistication.

Custom BUTTBILL Resin Button

The waistband features a custom BUTTBILL resin button, selected to complement the garment's minimalist design.

The button provides a secure and convenient closure while adding a subtle branded detail.

Its understated appearance blends naturally with the trousers' clean construction.

Premium YKK Nylon Zipper

The front fly is equipped with a YKK nylon zipper, designed for smooth operation and reliable everyday use.

The zipper provides convenient opening and closing while maintaining the trousers' clean front appearance.

Combined with the custom resin button, the closure system reflects the garment's attention to practical construction and refined detailing.

Comfortable Waist Construction

The double-pleated waist creates additional room around the upper portion of the trousers without compromising the overall silhouette.

This thoughtful design helps the fabric fall naturally while providing comfortable space for everyday movement.

The combination of relaxed proportions and carefully arranged pleats makes the trousers particularly suitable for commuting, casual outings, and extended daily wear.

Japanese-Inspired Minimalist Design

Inspired by the understated aesthetics of contemporary Japanese fashion, these trousers emphasize fabric texture, comfortable proportions, and functional construction.

The combination of garment-washed cotton-nylon fabric, double-pleated detailing, and a relaxed straight-leg silhouette creates a versatile and timeless appearance.

Rather than relying on excessive decorative elements, the design focuses on clean lines and balanced proportions.

The result is an everyday wardrobe essential that transitions effortlessly between casual outfits and contemporary smart-casual styling.

Care Instructions

Washing

Gentle hand washing or machine washing on a delicate cycle is recommended.

Wash at room temperature using a mild detergent suitable for cotton-blend fabrics.

Turn the trousers inside out before washing to help protect the fabric surface.

Wash dark-colored garments separately to minimize the possibility of color transfer.

Avoid using bleach or detergents containing optical brighteners.

Do not soak the garment for extended periods.

Avoid excessive rubbing or aggressive washing, which may affect the fabric's original texture.

Professional dry cleaning is also permitted.

Drying

Hang the trousers to dry naturally in a shaded, well-ventilated area.

Avoid prolonged exposure to direct sunlight, which may gradually affect the fabric's color.

Gently reshape the garment while damp to help maintain its original silhouette.

Do not twist or wring the fabric excessively.

Avoid high-temperature tumble drying, which may affect the garment's shape or cause shrinkage.

Natural air drying is recommended.

Ironing

Use a low-temperature iron setting, preferably below 110°C (230°F).

Iron the garment inside out whenever possible.

Place a protective cloth between the iron and fabric to help preserve its original texture.

Avoid ironing directly over the resin button or zipper.

Storage

Store the trousers in a cool, dry, and well-ventilated environment.

Hang them using suitable trouser hangers or fold them neatly to minimize unwanted creasing.

Avoid prolonged compression or tightly packed storage.

Keep the garment away from excessive moisture and direct sunlight.

Ensure the trousers are completely dry before storing them for extended periods.

Special Fabric Care Notes

These trousers are made from a 65% cotton and 35% nylon blend.

The combination of natural cotton and durable nylon fibers provides a balance of softness, comfort, and resistance to everyday wear.

Cotton fibers may experience slight shrinkage when exposed to excessive heat.

Nylon fibers should be protected from high temperatures to help maintain the fabric's structure and appearance.

The garment-washing process gives the trousers a soft, lived-in texture, but gradual changes in color and surface appearance may naturally occur with repeated washing.

To maintain the intended fit and appearance, avoid excessive heat, harsh detergents, and aggressive mechanical washing.

Always follow the physical garment care label if its instructions differ from these general recommendations.
