Our sun shirts allow you to spend hours outside in the sun without overheating or cooking your largest organ in UV radiation. Lightweight, airy, stylish, and fun, sun protection as rad as you!

Known for their show stopping appearance, venomous spines, and voracious appetites, invasive Indo-Pacific lionfish (Pterois volitans & Pterois miles) are the first non-native marine fish to become established in the Atlantic. Lionfish pose a significant threat to local marine ecosystems due to widespread predation of native species, prolific reproduction, and lack of controlling predators.

Advocate Apparel Inspired by the Indo-Pacific lionfish (Pterois volitans & Pterois miles)

Lionfish in their native range, from the South Pacific to the Red Sea, are an important part of the coral reef ecosystem and population numbers are kept in check through natural processes.

However, they are non-native to the Atlantic ocean and have become established as a harmful invasive species in this region, posing a significant threat to local marine ecosystems due to widespread predation on native species, prolific reproduction, and lack of controlling predators. Humans must intervene to reduce their impact in the invaded waters, and our Invasive Lionfish collection exists to promote action and awareness on this issue.

Beginning in the 1980s, two visually identical species of lionfish (Pterois miles and Pterois volitans) were introduced into the Atlantic via the US aquarium trade and have become the first non-native marine fish to become established in the Atlantic. Over the past decade, invasive lionfish densities in these non-native areas have exploded, as they have been documented along the entire US East Coast from Florida through Massachusetts, east to Bermuda, and south throughout the Caribbean. The expansion has been extremely rapid and exponential in scope.

Great fit; love the colors; just what I was hoping for!

Nice quality

I wear a ladies S/M and ordered a men’s S sun shirt with hood to use as a beach coverup top. It fits nicely over my swimsuit without being too tight or baggy. The hood design is good for a windy day if not wearing the hood; it doesn’t flop around in the wind. The fabric is slightly lighter than that used for leggings. Hence, it is not too thick and hot which I was worried about. Great product and fast delivery.

Rashguard hood is a problem

I hove my lionfish rashguard however I had to cut the hood off. It traps the air I breathe out and then makes the hood float. My shirt ends up strangling me. Suggest a rashguard without the hood.
