These revolutionary pads offer temperature specific to each treatment area, allowing for consistent cold delivery. The ergonomic design provides exceptional coverage, static compression, and user comfort. Intelli-Flo Pads are compatible with Polar Care Kodiak only. Proper use requires an insulation barrier between the Intelli-Flo Pads and the users skin. The water impermeable Sterile Polar Dressings offered by Breg provide an appropriate and complete barrier between the pad and the users skin (NOT INCLUDED).
