The Mountain Mermaid doesn’t choose between saltwater and summits — she belongs to both. Born of rivers, carried by tides, and crowned by sky, she’s as untamed as the world itself. This performance sun shirt carries her spirit: butter-soft against your skin, moisture-wicking to keep you cool, and UPF 50+ strong for every high ridge or wide horizon you chase.
It’s for the dreamers and wanderers who know their soul isn’t bound to one place — but to all of it.
Why you’ll love it:
Butter-soft feel with 100% microfiber performance polyester
Moisture-wicking fabric to keep you cool + dry
UPF 50+ sun protection for long days outdoors
Lightweight, classic fit with long sleeves for full coverage
Mountain Mermaid artwork printed bold on the back
Made in small batches, printed in-house
Small-Batch Release:
Like the river that runs to the sea, the Mountain Mermaid won’t stay long. Once this drop disappears, there’s no telling when it will return.

I ordered this two sizes larger than what I would normally get so when I need to wear it, it’s not so tight during the summer. It’s really nice very good material, it was exactly what I was looking for.
Nice shirt. Thanks
Love love love it! Shirt is so soft and perfect to wear in the sun and water .
When I get too much sun on my arms, I get sun bumps so this will definitely help me to stay out in the sun having fun longer.
Really comfortable and lightweight. Great for the Texas summer when it was 100° with humidity and a heat index of 112°.
The Siren Brew sun shirt arrived exactly as I hoped. The color was beautiful and I got so many compliments wearing it!
LOVE this shirt. It’s done a good job protecting me from the sun while on the water.
