An insulating device can include an aperture having a waterproof closure which allows access to the chamber within the insulating device. The closure can help prevent any fluid leakage into and out of the insulating device if the insulating device is overturned or in any configuration other than upright. The closure may also prevent any fluid from permeating into the chamber if the insulating device is exposed to precipitation, other fluid, or submersed under water. This construction results in an insulating chamber that is substantially impervious to water and other liquids when the closure is sealed.

A buoyancy dry bag includes an air valve unit, and first and second body parts that are connected to each other and that cooperatively define a receiving space. The first body part has a lining layer made of thermoplastic polyurethane, and an external layer structure having an inner layer disposed at an outer side of the lining layer and made of thermoplastic polyurethane, an outer layer contacting an outer surface of the inner layer and made of polyester, and a pattern layer contacting the outer layer. The first body part defines a first air chamber between the lining layer and the inner layer. The air valve unit includes a first air valve mounted to the external layer structure for injection of air into the first air chamber therethrough.
