Attends Air Dri Breathables Plus are designed specifically for air-flow therapy beds. These underpads improve air flow when the pad is wet or dry. Super absorbent polymers channel and lock fluids into the core and help prevent odor. The soft, cloth-like top sheet and back sheet covers the entire surface to promote healthy skin and reduces heat retention. Air Dri Breathables Plus Underpads have a heavy absorbency level.
