Ultimate Sun Protection Hat

Practical, lightweight and stylish, the Ultimate Sun Protection Hat is perfect for any activity where you spend prolonged periods in the sun, whether running a marathon or taking a walk around the block. The reflective panels block 99.8% of UV rays and reflect up to 80% of the sun’s heat rays. Stay cooler on sunny days with an advanced radiant barrier technology approved by NASA to protect astronauts from solar radiation in space. With a moisture-wicking sweatband, ventilated sides, adjustable sizing, and a chin strap, this hat is ready to take on the extremes, whatever your expedition. Covered by a wire mesh that protects the radiant barrier from damage, this creates the hat’s durable, breathable, and lightweight nylon construction. Packs easily (crush it) for travel.  One size fits most. 4 1/2" brim. UPF tested 800+.
