I would use elastic. Works on my underwear.
Elastic bands.
Elasticity is usually determined by far it can extend without breaking. A good example of something is very elastic is molten steel. When it is cooled, the elasticity is mostly removed.

Rubber bands
Elastic potential energy is stored in stretched or compressed elastic materials, such as a rubber band or a spring. When the material is deformed, this energy is stored in the material and can be released when the material returns to its original shape.
Most are made out of elastic bands with some type of material around the elastic (usually a nylon-type)
Muscles are made of a type of elastic tissue (sort of like the material in a rubber band).
Elastic deformation is a reversible change in shape or size of a material under stress, where the material returns to its original shape once the stress is removed. This type of deformation occurs within the elastic limit of the material, meaning it can withstand stress without undergoing permanent changes.
Factors that affect elastic energy include the material's elastic modulus (stiffness), the amount of deformation or stretching applied to the material, and the shape or configuration of the material. Additionally, temperature can also affect the elastic properties of a material.
The relationship between stiffness and elastic modulus in materials is that the elastic modulus is a measure of a material's stiffness. A higher elastic modulus indicates a stiffer material, while a lower elastic modulus indicates a more flexible material. In other words, stiffness and elastic modulus are directly related in that a higher elastic modulus corresponds to a higher stiffness in a material.
known as the elastic limit or elongation at break. It varies depending on the type of material and its tensile properties, such as strength and ductility. Once a material reaches its elastic limit, it will undergo plastic deformation and potentially tear if stretched further.
