3R M1251 Trousers Over Cold-Dyed Cotton Lyocell Darts - Grey Men's

Cold. Precise. Unrepeatable.

Cold dyeing is a process that works against heat — and that resistance is exactly what makes it interesting. LA HAINE INSIDE US applies this technique to a 52% cotton / 48% lyocell blend, submerging the fully constructed trouser in dye at low temperature. The result is a grey that settles unevenly into the fabric: deeper at the seams, lighter at the surface, with a tonal variation that no two pairs share. The 3R M1251 is an over trouser with darts, elastic waist, button closure, pockets, and laced hems — a garment built with precision, coloured with intention.

Why These Trousers Are Different

• Cold-Dyed Finish: Dyed after construction at low temperature — the grey absorbs unevenly by design, creating tonal depth and a lived-in quality that flat-dyed fabrics cannot replicate. Every pair is unique.
• 52% Cotton / 48% Lyocell Blend: Cotton provides structure and breathability; lyocell adds a fluid drape, natural sheen, and exceptional softness. Together they create a fabric that holds its shape while moving with the body.
• Darts Construction: Tailored darts give the over silhouette its shape — volume that is controlled, not accidental.
• Over Silhouette: Wide, relaxed through the leg — a deliberate proportion that reads as architectural rather than casual.
• Elastic Waist: Comfort without compromise — the elastic waist adapts to the body while maintaining the clean front line.
• Button Closure: A minimal front closure that keeps the silhouette uninterrupted.
• Pockets: Functional pockets integrated without disrupting the over silhouette.
• Laced Hems: Drawstring laces at the hem allow you to cinch or release the trouser leg — adjustable volume, adjustable proportion.
• Made in Italy: Designed and produced in Italy — craft embedded in every seam and dart.

Men's Size Chart

Over / wide leg fit. Measurements are of the garment, not the body. Elastic waist — accommodates a range within each size.

The Moment You Put Them On

The lyocell content is immediately felt — the fabric is softer than you expect, with a slight sheen that catches light differently from cotton alone. The over silhouette is wide but the darts give it direction: this is volume with intention, not volume by default. The elastic waist sits comfortably; the button closure keeps the front clean.

Cinch the laced hems and the trouser narrows at the ankle, creating a tapered silhouette from a wide leg. Release them and the fabric pools slightly — a different proportion, a different mood. The cold-dyed grey shifts between warm and cool depending on the light. No two pairs are identical.

The Art of Cold Dyeing

Standard garment dyeing uses heat to open the fabric fibres and drive colour deep into the material. Cold dyeing works differently: at lower temperatures, the dye penetrates more slowly and unevenly, settling into seams, stress points, and surface irregularities at its own pace. The result is a colour with tonal variation built into the fabric — not a uniform grey, but a grey that has depth, shadow, and a quality that improves with wear. The 52/48 cotton-lyocell blend is particularly receptive to this process: the lyocell's smooth fibre structure creates areas of higher sheen where the dye sits differently, while the cotton absorbs more deeply. The grey of the 3R M1251 is not applied — it has become the fabric.

How to Wear Them

• Tonal Grey: With a grey knit or cotton top — a monochrome register where the cold-dyed variation provides all the texture needed.
• Dark Contrast: With a black turtleneck or overshirt — the grey trouser reads as a considered lift against a dark upper body.
• Hem Cinched: Laces tied at the ankle with clean sneakers or leather boots — the tapered silhouette from a wide leg.
• Hem Released: Laces loose, fabric pooling slightly, worn with flat sandals or loafers — a more fluid, relaxed proportion.

Care Instructions

• Hand wash or delicate machine wash at 30°C
• Wash separately — cold-dyed pieces may release colour in early washes
• Do not tumble dry — hang to dry to preserve the over silhouette
• Iron on reverse at low-medium heat
• Dry away from direct sunlight to preserve the cold-dyed tone
• Expect and embrace slight colour evolution with wear — this is the nature of cold dyeing
