Abstract
A perspiration dissipating support assembly for head-mounted-display (HMD) devices. Variations of the perspiration dissipating support assembly disclosed herein enable supporting forces for an HMD device to be spread over a large portion of a user's head while facilitating dissipation of both liquid perspiration and vapor perspiration via respective dedicated dissipation mechanisms. In some embodiments, the perspiration dissipating support assembly includes a vapor-permeable contact layer that contacts the user's head and a vapor-permeable spacer that provides a Moisture Vapor Transmission Rate on the order of several times greater than that of the vapor-permeable contact layer. The vapor-permeable contact layer may have wicking properties that tend to draw perspiration (e.g., via capillary action resulting from a particular technical-weave pattern) away from the user's head and into the vapor-permeable spacer through which the perspiration evaporates into the ambient environment. The vapor-permeable spacer may be a three-dimensional fabric and/or an open-cell foam.
