Positionable container sleeve

A container sleeve, comprising:

• a body further comprising an interior surface, an exterior surface, and defining an inner volume;
• an attachment element connected to the body and exerting a magnetic force sufficient to support the body and a container in a predetermined position;
• and
• a cap connected to the body and positioned over a first surface of the attachment element so as to conceal the attachment element from the exterior surface of the body, wherein the cap has a coefficient of friction larger than a coefficient of friction of the exterior surface of the body.

A container sleeve comprising:

• a cylindrical body having an interior surface and an exterior surface, the interior surface defining an inner volume that holds a fluid container containing a fluid;
• the body further comprising an open end and a closed end;
• an attachment element coupled to the body, wherein the attachment element exerts a magnetic pull force;
• a strap that closes around the container at the open end;
• a strap adjuster that adjusts a length of the strap and holds the length of the strap;
• a cover attached to the exterior surface of the body and positioned to at least partially enclose the attachment element, wherein the cover supports a combined weight of at least the container, the fluid, the attachment element, and the cover and wherein the cover has a coefficient of friction that is at least a ratio of the combined weight divided by the magnetic pull force, and wherein the cover exerts an elastic force less than the magnetic pull force.
