ABSTRACT:
A device is disclosed for protection of a wearer's exposed skin against biting insects, and consists of a collar having a backing strip resistant to passage of liquid therethrough, an absorbent layer of open-cell solid resin foam impregnated with finely divided absorbent, and an outer porous covering. Liquid insect repellent is applied to the collar and absorbed, but then desorbs and evaporates at a slow rate to provide efficient protection when the collar is worn. Longer term protection using less chemical repellent than conventional methods is provided.
