HealthDri™ undergarments look almost identical to classic ladies' panties - but they offer absorbency and protection previously found only in disposable bladder control products. The secret is a patented moisture management design that rapidly takes moisture away from the skin, keeping it dry and reducing the possibility of irritation. The ultra-soft liner protects against leaks, rashes and odors. The absorbent insert disperses liquid without the uncomfortable lump associated with some undergarments. Made with 100% cotton for breathable comfort. Withstands more than 300 machine washings. Designed for heavy absorption (up to 6 oz.). Women's size 12 fits 38"-40" waist.
