“I bought my son and myself one of these shirts. They feel SO good to wear, and scream quality. They are substantial, yet light weight. We need them for Texas heat, and Colorado sun. We wore them all day and kept from getting burned to a crisp, while others did. When you need it, the hood pops up and fits SUPER comfy without being in your way. When wet, they do act like an air conditioner, allowing evaporation to hit your skin and cool you down in the oppressive heat/sun. Easy to wear all day, or week, on adventure.”
