Abstract: A collection bag has a bag body sized to fit along a wearer's torso. A back wall of the bag body is positionable in contact with the wearer's torso. A front wall is opposite the back wall. The back wall is formed from material that is generally impervious to items in the bag, while the front wall is generally pervious to water flow. The front and back walls are joined together along lateral and longitudinal margins to define the interior of the bag. Attachment members are attached to the bag body for supporting the weight of the bag body against the wearer's torso. A first sealable opening through the front wall allows the wearer to place collected items into the bag. A second sealable opening positioned along the lateral margin near the wearer's waste region allows the wearer to easily empty collected items from the bag.
