When the bugs are biting and the sun is beating down, cover up with the BugsAway® Baja Sun Hat. The structured all-around brim shields your eyes and head from the sun. Mesh-lined side panels provide maximum ventilation. The removable, adjustable clip-on chinstrap keeps the hat on, even in windy conditions. This soft, lightweight hat easily packs in your luggage or carry-on. BugsAway® apparel is treated with Insect Shield® technology, giving you the invisible, odorless protection of Permethrin that lasts up to 70 washes.
