Abstract
A neck dam collar is formed of a substantially vapor-proof material. Resiliently compressible portions of the collar either act as a cushion, a spacer, or both between a neck dam and the wearer's neck. In one embodiment, the collar is a discrete, cylindrical tube of flexible, elastic material. In another embodiment, a protective garment includes the neck dam collar.
