Brim - The brim extends out from the crown, keeping the rain and sun off your face and neck.
Fur Felt - An average of ten rabbit pelts (specially selected by Akubra), are required during a long and painstaking production involving as many as 200 individual operations. The result of using a fur felt is an incredibly light, resilient fabric, with a high strength-to-weight ratio. As well, the fur felt hat offers water-repellancy, a brim that harmful UVB and UVA rays can't penetrate and simple reshaping.
