sun visor

Car sun visor extenders are commonly made from materials like TPR (thermoplastic rubber) or polycarbonate. Women's sun visors and sun hats are often made from polyester or straw.

Care varies by product: many car visor extenders recommend spot cleaning or wiping clean. Some sun hats specify hand washing and then line-drying or laying flat to dry.

Many car visor extenders advertise UV protection (including UV400 in descriptions). Many women's sun hats advertise UPF 50+ protection, which blocks a high percentage of UVA/UVB rays.

They use adjustable mounting systems such as straps or clip-on locking mechanisms. Most are designed for quick, tool-free installation and to fit most car visors.

Many include adjustable closures (like Velcro) to customize fit—often accommodating head sizes up to about 22.8 inches—and some have ponytail openings for different hairstyles.

Women's visor hats commonly advertise wide brims around 4.5 inches, with some styles listing up to about 4.9 inches for extra coverage.
