<p>An elastic material is disclosed, including a breathable, closed cell foam panel. The elastic panel (310) includes recessed portions or channels (312) on at least one side, and apertures (314) therethrough, the apertures disposed in the channels (312). The channels may intersect to produce a network of flow paths for heat and sweat transfer, or may comprise nonintersecting channels that establish a directional flow path. In another embodiment, the channels define a plurality of protrusions, such as circular protrusions (332) or rectangular protrusions (342). The elastic panel is preferably formed by compressing a sheet of closed cell foam between a pair of oppositely disposed, heated plates (410, 420), wherein one of the plates includes a plurality of pins (422), and the other of the plates includes apertures (414) adapted to receive the pins. One or both of the plates includes protrusions (412) for forming the recessed portions or channels. <IMAGE></p> |
