Only available from Hammacher Schlemmer, this is the 100% cotton beach towel that repels mosquitos from your personal space. It uses a nanoparticle matrix to bind a non-toxic repellent approved by the World Health Organization to the towel’s fibers to provide odorless protection against mosquitos. The active ingredient (IR3535) is a synthetic amino acid developed in the 1970s commonly used in lotions and sprays that distort mosquitos sense of smell and keeps them up to 18" away. The towel helps protect against insect-borne illnesses such as the Zika virus, West Nile virus, and Lyme disease, as well as the discomfort of itchy welts. While standard insect repellents must be reapplied after swimming or sunbathing, this towel provides continuous and environmentally friendly protection against mosquitos without DEET, sprays, candles, or fragrances. 100 wash efficacy. Imported. Red. 67" L x 39 1/2" W. (27 oz.)
