Sun Barrier 100 Short Jacket This is a completely light-blocking jacket that cuts 100% of UV rays, 100% of infrared rays, and 100% of visible light. The length is shortened, and mesh material is used for the lining to eliminate the stickiness of sweat, reducing stuffiness. It firmly guards areas that tend to be unprotected, such as the arms, neck, and back of the hands. (Quoted from the official website) I received this, but it doesn't fit, so I'm selling it. This has only been tried on once. It is unknown whether it is after or before the renewal. No significant price reduction.
