Surfing clothes generally use elastic fabrics, add astigmatism materials and filter ultraviolet rays. Generally, the SPF coefficient can reach more than 50. The advantage is that there is no need for sun protection. Swimsuit is usually cotton or quick-drying.
2. Different styles:
Surfing clothes are tight. Swimsuit is a loose style.
Usage: just wear it on your body, which can be understood as a tight-fitting long-sleeved sunscreen T-shirt made of swimsuit fabric.
