Stone Island explores oxidised copper in its new trench coat

Stone Island presents its fifth Prototype Research_Series at Milan Design Week. This time, the brand explores oxidised copper to create a trench coat that changes colour as you wear it. 

Prototype Research_Series is a collection of limited edition pieces, each of which has been made with fabrics or treatments that the label has discovered through its research and experimentation programme. To date, none of these techniques have yet been realised on an industrial scale.

For the fifth edition, Stone Island has created a trench coat with its classic Raso cotton. This material has then been bonded to a non-woven fabric with a nanometric copper layer. Each jacket will change as it is worn, i.e. it changes depending on the conditions it is exposed to.

The collection is on display as part of Milan Design Week and runs until 10 September.
