- 4100002 Hand Sprayed Reflective Light Bull Denim-TC
One jacket, two layers
The Slate Blue 4100002 is cut in a Regular fit and comes with a detachable down-filled vest. Worn together, the pieces give this reference its layered construction; the vest can also be removed.1
A light denim with a firm weave
The shell uses 13 oz denim in a 3/1 twill. Stone Island attributes the fabric’s notable resistance to that weave, a structural detail that gives the lightweight denim its definition.1
A shaded reflective surface
The denim is garment-dyed, laminated with a high-refractive film containing glass microspheres, then hand-sprayed to create a shaded effect. A specific anti-drop treatment completes the surface finish.1
Cotton, down and a stated origin
The maker says the cotton comes from regenerative agriculture and identifies the detachable vest as RDS-certified. It lists the jacket as made in Romania, a country-of-manufacture detail specific to this reference.1
Keep the care instructions separate
The jacket is 100% cotton. Its detachable inner vest has a polyamide shell and lining with polyurethane-resin coatings, and an 80% duck-down, 20% duck-feather filling. The jacket calls for delicate hand washing up to 40°C and no tumble drying; the vest has a separate gentle-wash limit of 30°C and permits low-temperature tumble drying.1
Detach first; compare the two care limits
| Exact 4100002 component | Washing limit | Tumble drying |
|---|---|---|
| Cotton outer jacket | Delicate hand wash, maximum 40°C | Do not tumble dry |
| Detachable down-filled vest | Gentle wash, maximum 30°C | Low-temperature tumble drying permitted |
The outer jacket’s surface is also a sequence rather than a single coloured cloth: garment dyeing comes before lamination with a glass-microsphere film, followed by hand spraying for the shaded effect. Keeping the vest separate makes the contrasting care limits understandable. Use the garment’s complete instructions as well as these two headline limits; they include removing detachable accessories and, for the jacket, avoiding twisting or wringing.1
