I bought this for a vacation in Hawaii and it was my go-to top the whole time. I used it for hiking, paddle boarding, snorkeling, all of it. I pulled the hood up during rain storms, I protected my face from bugs and my neck from sun, and I often appreciated the extra lightweight, breathable, layer when the wind kicked up. And it looks cute on.I�m a size 14 on top with thick upper arms and a 38DD chest. The large fit me perfectly.My only complaint is that the sleeves are really, really short. The end of the sleeve fell two full inches short of my wrist, which was extra annoying because there are thumb holes I wanted to use but needed about 5 more inches of sleeve to even think about it.Overall this is a great top from a quality brand. Highly recommend.
