From Old French escharpe.
escharpe f (plural escharpes)
Possibly from Frankish *skirpa, *skirpja (“basket made of rushes”) or of other Germanic origin, compare Old Norse skreppa (“small bag, wallet, satchel”). Norse origin is suggested by the variants eschreppe, escreppe, escrepe (compare Medieval Latin scrippum (“pilgrim's pack”), further compare English scrip); maybe a Norse borrowing was conflated with a Frankish borrowing.
Alternatively from Medieval Latin scirpa, schirpa (“little woven bag of rushes, pilgrim's pack”) (compare Classical Latin scirpea (“large basket made of bullrushes”)), from Latin scirpus (“rush, bullrush”). The Frankish word itself may ultimately be borrowed from Latin, either directly from scirpea, or derived from scirpus.
