We've seen some innovative knitwear recently, but these sweaters from Stone Island are the most impressive.
The capsule is called Ice Knit, and is made from exclusive thermo-sensitive yarn which drastically changes colour when the temperature changes.
What's impressive is that this sweater reacts to external temperatures, rather than your temperature (discoloured armpits are never a good look).
This is achieved by a strong double-knit construction, with the outer face crafted from the thermo-sensitive yarn, while the inner layer is made from pure wool.
Ice Knit is available in three different colours, emerald-to-military green, ivory-to-anthracite, and yellow-to-orange.
Check them out below:
The pieces are available from Stone Island's website, although with limited availability, you may have to resort to resale.
Each piece will cost £1,395.
