pourpoint (n.)

also purpoint, "something quilted," used especially of garments worn by men late 14c.-15c., early 15c., from Old French porpoint, noun use of the past participle of porpoindre "to perforate," from *por-, a Vulgar Latin variant of Latin pro- (itself here a substitute for per- "through") + poindre "to stab, pierce with a pointed object, from Latin pungere "to prick" (from suffixed form of PIE root *peuk- "to prick").

Not to be confused with pour-point "temperature below which an oil is too viscous to be poured" (by 1932).
