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.

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.

Great shirt for being in the sun. Size up if you can!

This is an awesome rash guard, but i bought it as a sun shirt. I got a 2 XL which is generally loose on me for other clothing, and this fits like a rash guard, so it's tighter than i like for walking around town or hanging at the beach. That being said, it would work for me snorkeling or surfing fine, since it's supposed to be tight and not dragging in the water. I'll order a different style in 3 XL and see how that works. Great product, love the way it fits if I go scuba diving could wear under my gear to look like something most fish don't want to eat. :) (FYI, i am 5-11 and 210-215 lbs) I would say the fit is OK if you are at the low end of the scale (2 XL chest is 45-49 where as 3 XL is 49-53) for a sun shirt, top end of the scale is a rash guard fit. So i'm a 48 chest, so a 2XL fits like a rash guard and 3 XL like a sun shirt. Hope this clarification helps!
