The Mosquito Repelling UPF Hat

This is the hat that uses a permethrin-permeated fabric layer to repel mosquitos. Recommended by the World Health Organization and the U.S. Centers for Disease Control and Prevention for use on apparel, permethrin is an odorless synthetic insecticide that simulates the natural repellent compounds issued by chrysanthemums. The hat is EPA-registered and helps to prevent insect-borne illnesses such as the Zika virus, West Nile virus, and Lyme disease, as well as the discomfort of welts. Unlike repellent sprays that must be constantly reapplied, the hat provides continuous protection against insects without DEET or fragrances. The nylon mesh keeps the head cool with a moisture wicking sweatband and breathable ventilation system built into the crown, and protects against the sun with a 3 1/2" wide brim and UPF 50+ rating. An adjustable chin strap keeps it securely fastened. Retains mosquito repellency for 70 washings. Imported. Khaki. If in between sizes, order the next size up. M (hat size 7-7 1/8; head circumference 22-22 1/2"), L (7 1/4-7 3/8; 22 3/4-23 1/4"), or XL (7 1/2-7 5/8; 23 5/8-24").
