This Curity Unna Boot with Calamine is formulated with nonhardening zinc oxide paste which allows the bandage to remain flexible thereby encouraging patient ambulation and compliance, and it is gelatin-free thus eliminating the need for preservatives which in turn reduces the chance of adverse skin reactions. Plus, it is made of soft, non-raveling, 100% cotton gauze; conforms well to leg contours for a comfortable fit; and helps deliver firm, even compression therapy for a multitude of bandaging needs.
