A neck gaiter for sun protection, also known as a sun gaiter or UV neck gaiter, is a versatile piece of clothing designed to shield the neck and face from harmful ultraviolet (UV) rays, and sometimes also from cold or wind. It's a tubular fabric, made of UPF-rated material.
 
Sun Protection: Neck gaiters are designed to protect the wearer from sunburn and the long-term effects of sun exposure, such as premature aging and skin cancer. 
 
UPF Rating: Look for gaiters with a UPF (Ultraviolet Protection Factor) rating, which indicates how effectively the fabric blocks UV radiation. 
 
Versatile Wear: They can be worn in multiple ways, including around the neck, over the nose and mouth, or as a headband, providing flexibility for different activities and weather conditions. 
 
Breathable and Moisture-Wicking: Many neck gaiters are made from breathable, moisture-wicking fabrics, keeping you cool and comfortable during warm weather activities. 
 
Warm-Weather and Cold-Weather Use: While often associated with sun protection, they can also be useful in colder weather to protect against wind and cold. 
 
Outdoor Activities: Neck gaiters are popular for various outdoor activities like hiking, running, fishing, biking, and more. 
 
Alternative to Sunscreen: They can be a convenient alternative to sunscreen, especially for extended periods outdoors or for those who prefer not to use sunscreen.
