Activity ostomy bag

An ostomy receiving bag comprising a front wall sealed to a rear wall along a sealed rim and having a top end and a bottom end,

• the top end of the rear wall is provided with an inlet and the bottom end provides an outlet tail extending away from the front and rear walls with a closable outlet at the bottom end;
• a cover sheet separate from the outlet tail and secured to the sealed rim of one of the front and rear walls, the cover sheet including a cut that at least one of a top edge and an opposing bottom edge of the cover sheet has a central portion that is not attached to one of the front and rear walls;
• and
• one of a first half of a fixation pair is placed on a top end portion of the receiving bag, and a second half of the fixation pair is placed on a bottom end portion of the receiving bag;
• wherein attachment of the second half of the fixation pair to the first half of the fixation pair locates the outlet tail on the top end portion of the receiving bag between the cover sheet and one of the front and rear walls to reduce a collection volume of the ostomy receiving bag and to cover a majority of the outlet tail from view;
• further wherein separation of the second half of the fixation pair from the first half of the fixation pair allows expansion of the collection volume of the ostomy receiving bag for use with the closable outlet closed.
