For outdoor practice, jika-tabi (地下足袋) are worn. As uchidachi always faces sun, this role can be very blinding, but it is not allowed to wear sunglasses or hats. However, in extremely cold conditions one can wear a hat (without sun reflector) and other extra protective clothing. When one has not enough hair or eyebrows or in extreme hot conditions, one can wear a tenugui (手拭い) or hachimaki (鉢巻) to prevent sweat irritating the eyes or to keep hair out of the face. Note that tabi and jiki-tabi should preferably match the colour of the hakama.
