1. A fibre for use in artificial turf, the fibre having an elongate cross-sectional shape defining a first face and a second face that meet at side edges of the fibre, wherein a maximum thickness of the fibre is between 0.2 mm and 0.6 mm, determined based on a largest diameter circle that can fit within the cross-sectional shape and a ratio between the maximum thickness of the fibre and a length of a centre line extending between the side edges is between 0.3 and 0.6 and no part of the first and second faces crosses the centre line, wherein the largest diameter circle fits in a first position and a second position of the cross-sectional shape, wherein the first face has a first ridge which lies on a diameter of the largest diameter circle in the first position and the second face has a second ridge which lies on a diameter of the largest diameter circle in the second position, wherein the first ridge and the second ridge are offset with respect to each other and such that the cross-sectional shape is 2-fold rotationally symmetric with no reflectional symmetry.
