Stone Island Heavyweight Slim Straight Drawcord Sweatpants - 2 Colors

Heavyweight. Smooth Face. Front Crease. Zip Hem.

The fabric here is a smooth-face heavyweight knit — not a standard fleece, not a brushed interior loopback. The outer surface is flat, even, and carries a low ambient sheen consistent with a high-density double-knit or bonded construction. There is no visible texture, no pile, no surface variation: just a clean, uniform face that holds its shape and reads as a structured material rather than a soft jersey. Weight is the operative word. This is a cold-weather trouser built for coverage and body, not drape.

The silhouette is slim straight — fitted through the thigh, consistent in width to the ankle, no taper. The defining structural detail is the front center crease: a vertical pressed line that runs from the waistband to the hem on each leg. This single element shifts the visual register of the trouser from casual to tailored-adjacent, lending a vertical linearity that reads as intentional construction rather than athletic styling.

The waistband is elasticated with a functional white drawcord — the white cord is consistent across both colourways, creating a visible contrast element at the front of the Black version and a tonal-adjacent detail on the light Pink-Gray. Side slant pockets are present at both hips, with clean diagonal pocket mouths. No rear pockets, no side stripes, no leg paneling.

At the hem: zip closure at each cuff. A small zip opens at the ankle seam, allowing the hem to be opened for fit adjustment or styling. This is a functional construction detail visible in both colourways.

The SI compass badge is positioned on the right leg at the upper thigh: a square black-ground badge with the yellow-green compass rose, the same hardware across both colourways.

Two colourways. Six sizes: M through 4XL.

Pink (Light Cool-Toned Pink-Gray)

A pale, cool-register colour that reads as a neutral pink-gray rather than a warm or saturated pink — the tone sits at the intersection of gray and blush, with the fabric's smooth surface giving it a slight luminous quality under light. The white drawcord sits in near-tonal relationship with the pale ground. SI badge in black with yellow-green compass at right thigh. The most understated colourway in the range, with no warm or chromatic intensity.

Black (Deep Charcoal-Black)

Full deep charcoal-black ground. The smooth heavyweight face absorbs light evenly, with no visible sheen at this depth. The white drawcord at the waist is the sole contrasting element on the trouser — a deliberate structural punctuation against the all-black surface. SI badge with yellow-green compass at right thigh. Zip hem at ankle in matching tone.
