Abstract: A bottle holder includes an anchor arm a grip loop, and a rigid member. The anchor arm includes a plurality of bends and a plurality of segments. A segment is a portion of the anchor arm between two adjacent bends of the plurality of bends. At least two segments of the plurality of segments of the anchor arm each include a snap aperture. The grip loop forms a bottle aperture for holding a bottle disposed at a proximal end of the anchor arm. The rigid member is disposed at a distal end of the anchor arm. Each snap aperture of the at least two segments of the plurality of segments of the anchor arm are configured to receive the rigid member. In some cases, the grip loop, the anchor arm, and the rigid member are made of a single piece of elastic silicon material.
