In 2023, Knirps and Karhu came up with the 'Shitty Weather' pack, consisting of two colorways of the Karhu Fusion 2.0. One of the colorways was the 'Plum Kitten' (F804160), a dark grey sneaker made with a water-repellent material. 

The Knirps x Karhu Fusion 2.0 'Plum Kitten' combines the colours grey, black and dark blue. The Fusion 2.0 silhouette features a sleek design. A toggle is placed on the tongue which gives the pair an outdoorsy feel. The speckled, grey sole gives the pair a rugged look. Weather or no weather - the Knirps x Karhu Fusion 2.0 'Plum Kitten' is a suitable pair for any sneaker lover.
