We've dialed in everything adventurers love about the Astroman fabric and created a custom cut for women that takes into consideration backpack belts, hip-hugging harnesses, and pocket placements. Meet the Women's Astroman Sun Hoodie: Our best-selling lightweight, stretchy, and ultra durable fabric packed with the highest rating of UPF 50 sun protection. Named after the legendary climb in Yosemite Valley, the Astroman was built for exposed and rugged climbs, but works equally as well for hiking, paddling, backpacking, or any other activity when you're headed out in the blazing sun. The hoodie version might be our favorite for protecting ears and back of neck, while fitting easily underneath a helmet. It even packs up small into its own zip pocket, taking up minimal space in your backpack for a handy extra layer of sun protection.
