Alchemi Labs River Sun Hat with Radiant Barrier Technology

Stay cooler on hot, sunny days by reflecting the sun's heat with advanced radiant barrier technology from Alchemi Labs. The reflective panels block 99.8% of UV rays and reflect up to 80% of the sun's heat rays. The same technology is used 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. The streamlined crown and asymmetrical brim (wider in the back) is suitable for more active use, and is a favorite for paddle sports, gardening, hiking, and much more.

• Radiant barrier on top of crown and brim: UPF tested 800+, blocks 99.8% of UV rays, reflects up to 80% of the sun's heat waves
• Moisture-wicking sweatband
• Adjustable cinch strap to fine tune sizing
• Chin strap with barrel lock to help secure the hat on windy days
