Abstract: A waterproof glove with a shaft incorporating a hand insertion opening and a shaft edge located at the hand insertion opening side and consisting of a shell material. A waterproof cuff sleeve with a lower cuff edge is arranged inside of the shaft such that it lies below the shaft edge by a predetermined underlength and is connected with the shaft edge and with an upper cuff edge that projects over the shaft edge by a predetermined overlength. A sleeve accomodation groove is formed between the shaft and the sleeve cuff so that a lower end area of a wearer's garment sleeve can be inserted into the sleeve accomodation groove. A groove base formed in the lower cuff edge is sealed so that water from the sleeve accomodation groove cannot reach the interior of the glove. The overlength of the cuff sleeve is dimensioned such that when the wearer holds the hand in such a position that water can accumulate in the sleeve groove, water from the sleeve groove cannot reach the upper edge of the cuff.
