Ethical stewardship, crafted on demand on eco-friendly, GRS-certified fabric. Your purchase supports our family apostolate and our mission to give back to pro-life and Catholic organizations.
Palm trees and the "It's Three O'Clock Somewhere" slogan all over print. High visibility color for water safety. The design says "It's Three O'Clock Somewhere", inspired by the classic Jimmy Buffett anthem but dedicated to the hour of "MerSea"! It's a reminder that no matter where the tide takes you, it's always the right time for grace.
To make your swim gear last longer, thoroughly rinse off after each use to get rid of any chlorine/salt residue.
• Very soft four-way stretch fabric that stretches and recovers on the cross and lengthwise grains
• Flat seam and coverstitch
Disclaimer: To make your rash guard last longer, thoroughly rinse it off after each use and get rid of any chlorine/salt residue. This product runs small and is quite fitted. For a more comfortable fit, we suggest choosing one size up.
This product is made especially for you as soon as you place an order, which is why it takes us a bit longer to deliver it to you. Making products on demand instead of in bulk helps reduce overproduction, so thank you for making thoughtful purchasing decisions!

At MerSea Designs, we believe in evangelizing without saying a word. We create high-quality, Catholic-inspired apparel and accessories that help you wear your faith on your sleeve—literally. Driven by a passion for design and a love for the Church, we’re here to help you reflect Christ everywhere you go.
MerSea Designs is a small family apostolate, not a large corporation. We started this journey because we are in love with our Catholic faith and wanted a way to share that love through beautiful, well-crafted fashion.
When you shop with us, you can rest easy knowing your values are protected. Unlike many modern brands, we never funnel profits into causes that oppose Catholic teachings. Instead, a portion of every sale goes directly to pro-life and pro-Catholic organizations. When you support MerSea, you aren’t just buying a shirt—you’re supporting a small family apostolate that believes what you believe.
Thank you for your patronage, we are humbled by your prayers and support.
I saw a group of people praying the rosary on the beach a couple of them were wearing these awesome shirts. They showed me the website and now I have a few of the catholic button up shirts, I'm always getting the best compliments about them.
Product quality is top-notch. Size and fit are AMAZING. Will be wearing this to my upcoming retreat. I honestly can’t recommend them enough.
Awesome catholic hoodies. So cozy! Great Fit! It's perfect. Great way to wear my faith on my sleeve! I will definitely be coming back.
We are a Catholic, family-owned apostolate based in sunny Southern California and dedicated to sharing our Faith through Fashion for the Greater Glory of God. Our name is a playful nod to the ocean we love {inspired by Christina's love for the sea} and a tribute to the daily gifts of Grace and Mercy we receive.
Led by designer (and self-proclaimed mermaid) Christina Chidley, we balance our addiction to summer fun, with a deep devotion to faith and family. Based in landlocked reality, but with a saltwater soul, Christina, balances her time between her growing family, teaching catechism with her homeschool co-op, creating awesome designs, and being a Son Chaser (as well as a sun-chaser).
Whether you found us online or at a pop-up event, we are honored to serve you.
We hope our "Catholic" Hawaiian Shirts help you "Live in the Light", to be Salt & Sol (light) for those around you. We believe every creation we make should honor God, which is why, a portion of every sale supports Pro-Life and Catholic charities.
