Quarpel is a durable water-repellent and oil-resistant treatment for textiles developed at the Quartermaster Research and Development Laboratories in 1959.

The Quarpel treatment could withstand up to 15 launderings without re-treatment and still retain greater water repellency than the best vapor permeable raincoats then on the market. Fabrics treated with the compound remained vapor permeable and free from uncomfortable moisture condensation.
