I love my Coolibar UPF50+ Women's ZnO Seaside Hoodie!!! It's very light and soft. I used it while I was back home in Hawaii.  It worked great as a cover-up to keep the sun off my arms. With the island trade winds blowing and sun shining, it worked great. But without winds blowing, it was a just a little warm on the arms, but at least it was light in weight, so I could still wear it.
