Made with Microfine antimicrobial fibers technology, Ultra-Dry Crate & Kennel Pads protect your dog during transport or while spending time in their crate. Constructed with a "stay-dry" material next to your dog that is porous and non-absorbent allowing fluid to pass through to three middle layers of Microfine moisture dispersion fabric. The bottom layer is a barrier layer that prevents urine from soaking through and protects the orthopedic foam core of the pad.
