Frequently Asked Questions
How does it protect against the sun?
A: The tightly woven fabric provides physical coverage that helps shield skin during long sun-exposed days on the water or trail.
How fast does it dry?
A: The polyester-rich weave wicks moisture to the surface and dries much faster than cotton, so it stays light after spray, sweat, or a quick rinse.
Is it breathable in heat?
A: Yes. The lightweight, airflow-oriented weave is built for warm and humid conditions.
Can I wear it over a base layer?
A: It is designed as a warm-weather layer worn next to skin, but the athletic cut leaves room for a thin base if you prefer.
How should I wash it?
A: Machine wash cold and hang or tumble dry low. Avoid fabric softener, which can reduce wicking performance.
