Made of 100% polyester mesh fabric, the Sentinel Headnet keeps your head protected against pesky bugs during all your outdoor adventures. The headnet is treated with an Insect Shield finish to repel mosquitoes, ticks, ants, flies, chiggers, and no-see-ums. This odorless treatment is EPA-registered and is guaranteed to last over 70 washes. The Spring-Ring metal hoop keeps the mesh off your face, while the drawcord closure seals in the netting. The Sentinel is designed to be large enough to accommodate wide-brimmed hats, and folds easily for compact storage. Built-in pocket. Imported.
