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.
