This is a great top for sun protection. I especially like the white color, as it doesn't get too hot and looks nice. This is, as other reviewers have noted, on the loose side. It might not be ideal for lots of time in the water, where a form fitting top would be best. However, for sun protection and a nice loose fit, this top is great.
This is the most useful rashguard. The 3/4 length sleeves are good for sun protection in the summer without being too hot, or are a good length to fit under a wetsuit in the winter. I love the white because it doesn't get too hot in the sun.
This rashguard is a really nice length, it's slightly longer than average. I usually size up a size on my rashguards which worked well with this one too. It's snug and doesn't stretch out in the water.
