Fill material determines how much liquid an underpad can absorb and how quickly it draws moisture away from the surface. Poly/rayon blends are popular for their quick absorption and good fluid retention, while other materials may offer different balances of absorbency and bulk. The Salk 1999 CareFor Deluxe Washable Underpad contains a 10 oz. poly/rayon soaker, making it highly absorbent and effective at trapping fluids. With various fill materials on the market, you can choose the one that aligns with your absorbency requirements and comfort preferences.
