runproof
Won't ladder, guaranteed
Runproof describes fabric, especially hosiery and stockings, designed to resist runs—those ladder-like tears that spread through knitted material when a thread breaks.
These runproof tights have survived three washes.
The term also applies to mascara and other cosmetics formulated not to streak or smear when wet: runproof eyeliner.
