Sun Barrier 100 Parka, Gray This is a fully light-blocking parka that cuts 100% of ultraviolet rays, 100% of infrared rays, and 100% of visible light. I purchased it about 3 years ago and used it for only one summer season. I haven't used it for the past two years, so I'm putting it up for sale. I used it for a short time while working. However, the mesh part on the sides has some fraying. There are no pockets.
