When the temperatures drop, this adidas by Stella McCartney beanie helps keep you warmed up — all thanks to the cosy (and fashionable) rib-knit structure. It feels just as at home on the trails as it does wandering the city streets, with the bold pop of colour topping off any look with confidence. This product is made with at least 50% recycled materials.
