Abstract
A bladder includes a first polymeric film, a second polymeric film attached to the first polymeric film to form a chamber, and one or more grooves formed in an exterior surface of the chamber. In one configuration, the grooves are formed in the exterior surface of the chamber by subjecting the chamber to a laser-etching process.

A method comprising:
- providing a bladder comprising one or more polymeric films defining a chamber of the bladder;
- and
- lasering at least one of the one or more polymeric films forming at least a portion of an exterior surface of the bladder to form one or more depressions in the exterior surface of the bladder.
A bladder comprising:
- a first polymeric film;
- a second polymeric film attached to the first polymeric film to form a chamber;
- and
- one or more depressions formed in an exterior surface of the bladder at one or more locations on at least one of the first polymeric film and the second polymeric film, the at least one of the first polymeric film and the second polymeric film having a reduced thickness at the one or more locations compared to surrounding portions of the at least one of the first polymeric film and the second polymeric film.
