The AFTCO Sun Protection Hood is a mask/hood garment featuring a UPF 50 sun protection rating which offers the wearer protection from the sun's harmful UV rays. The sun protection hood, from AFTCO, is designed to offer complete coverage of the neck, face and head. This hood is extremely light in weight and quite comfortable due to the stretchy nature of the 92/8 polyester/spandex blend fabric and the use of over-lock stitching that won't cause any irritation or chaffing. The material is naturally breathable allowing good air circulation throughout and features laser cut holes at the nose/mouth area for increased ventilation keeping sunglasses from fogging up. While the weather may be beautiful, the harmful UV rays can be quite dangerous and have been linked to skin cancer as well as other diseases. According to the Skin Cancer Foundation, clothing is the single most effective preventative measure against skin cancer. The UPF 50 rating displayed by this garment, is the highest attainable for clothing and will protect the wearer all day without issue. At the very least, wearing this hood will prevent a nasty sun burn and allow you to more thoroughly enjoy your time fishing. We offer the AFTCO in a single "one size fits most" size.
