Designed for a flexible fit, the Hunter Wellies Womens Original Back Adjustable Navy mirrors the iconic Original Tall with the addition of an expandable gusset at the back. Perfect for a wider calf, these matte wellies in classic navy offer ease of movement and adjust from the traditional tailored Hunter fit to a more relaxed shape when the gusset is fully extended. Handcrafted from natural rubber, the Original Adjustable boot is fully waterproof with a comfortable polyester lining and the signature Hunter Original tread.
