This season’s magic trick from Stone Island sees the wearer of their latest thermosensitive fabric become subtly camouflaged as changes in temperature mute the material’s pattern. The Heat Reactive fabric is the latest brainchild of their industrious R&D department – which is surely among the hardest working in all of fashiondom – and arrives in parka and jacket form.

Both styles come in a single, permanent colour that soon becomes three as changes in temperature morph the jacket into what must feel like a totally new jacket. Three in one, we’re into it.
