A device includes a textile main body, and one or more indicator elements on the textile main body, or on a label fixed to the textile main body, for indicating date information. The indicator elements include a plurality of severable portions spaced from the main body or the label on which they are provided. Each of the severable portions is associated with date information such that by cutting one or more of the severable portions a date of use of the device or a date of inspection of the device is indicated. A device having indicator elements of this type has the advantage that the indication of a date of first use or a date of inspection can be made easily, can be read easily and will be durable over many laundry cycles.
