Scuba Diver T-Shirts
Nothing screams “I Like Diving!” more than wearing an absolutely ridiculous scuba diver T-shirt. Everyone else is busy showing off their “I’ve been to the world’s most overcrowded reefs” shirts from Bonaire, Cozumel, Florida, the Maldives, Thailand… yawn. You? You’re smarter than that. You know style points matter. You have color-coordinated dive gear. You are ready to change things up.
That’s why we made CERTIFIED MOUTH BREATHER and ANEMONEFISH DIVER T-shirt designs. They’re not just shirts—they’re a declaration that you’ve got serious underwater talent, minimal taste, and a sense of humor that’ll surface faster than an over-inflated BCD.
Don’t just “try them on.” Buy them. Wear them. Flaunt them. And check back often—we’re dropping new designs regularly, because the ocean isn’t the only thing worth exploring. So is that awful collection of worn-out scuba shirts you buried in your bottom dresser drawer.

Whoever said being a mouth breather was a bad thing? Well, plenty of people, actually… but those judgmental erudites have probably never strapped on a tank and dropped below the surface into the abyss. Down there, mouth breathing isn’t lazy, it’s survival. It’s pure skill. It’s the mark of the entitled few who spent way too much money just for the privilege of doing it. That’s right: you, me, and all our dive buddies, we’re all CERTIFIED MOUTH BREATHERS.
Nose breathers? Cute on land. Absolutely useless at depth. This shirt takes an old insult and turns it into a diver’s badge of honor. It’s the perfect pre- or post-dive uniform, surface-interval conversation starter, and instant secret handshake for anyone who’s ever taken a sketchy fill and wondered if that jerk at the dive shop was trying to kill them. Available in both men’s and women’s designs, this isn’t just another ugly diver T-shirt, it’s a cheeky declaration of who we are at the most basic of. Wear it proudly. Because underwater, every last one of us is nothing more and nothing less than a CERTIFIED MOUTH BREATHER.

Sure, the ocean is full of sharks, rays, and epic wrecks—but let’s be honest, nothing pulls a diver’s heartstrings quite like an anemonefish (clownfish) peeking out of its anemone home. The circular designed ANEMONEFISH DIVER series of T-shirts pays homage to the many species of anemonefish, wrapped in a reef-inspired frame that makes it as stylish topside as it is underwater.
It’s bold without being loud, playful without being silly—perfect whether you’re rinsing gear on deck, grabbing post-dive drinks, or just reminding landlubbers that you actually know Nemo personally.
Because who says a diver T-shirt can’t be as graceful as the person wearing it? Look for more designs coming soon...

Behold! You thought a single CERTIFIED MOUTH BREATHER tee was enough to cement your place among the chosen, but lo—Version #2 rises from the depths, adorned with not one, but two sacred emblems.
On the front, a crest declaring your allegiance. On the back, the same banner carried proudly between your shoulder blades, so as you stride across the dock to that broken-down scow of a dive boat, the neoprened flock may witness your devotion from bow to stern.
Yes, this garment commands a higher tribute of bullion, but such is the price of glory. For when the boat deck howls in laughter and sighs with envy, when shipmates shout, “Name your shirt source, noble diver!”—you shall know the investment was just.
Cast aside the feeble rules of fashion. This is no ordinary shirt. This is a rite. A relic. A wearable proclamation: I breathe through my mouth, and I am certified.

Sharks, rays, eels. All macho fish species that can be found, well, in any ocean—but nothing shows your well-traveled manhood quite like a T-shirt proclaiming your soft spot for one of the ocean’s most flamboyant and flirty inhabitants. Yes, my friend. You are a camera-equipped Anemonefish Diver.
These charismatic little fish are only found in the warm, exotic waters of the Indo-Pacific, Red Sea, and Great Barrier Reef—exactly the kind of places where real divers go to “test gear.” If you’ve ever hovered motionless for 17 minutes just to get a clean shot of a clownfish peeking out of a waving anemone (and trust, me we know the feeling), this shirt is for you!
Wrapped in a coral reef frame bursting with color, this design reminds everyone that while the rest of the dive group was chasing pelagics, you were getting the money shot. Bonus points if your camera rig weighs more than your checked luggage.
Perfect for post-dive beers, camera room bragging rights, or casually letting the world know that you’ve dived the Coral Triangle and have the anemone footage to prove it.
Coming soon: More designs for divers who take their style almost as seriously as keeping their dive budget a secret from their significant other.

Forget cleansing breaths, Wim Hof breathing, and whatever your smartwatch tells you about “mindful inhalation.” You’re a scuba diver, which means you’ve mastered the ancient art of sucking air through a hose like your life depends on it—because it literally does. That's right, you are a CERTIFIED MOUTH BREATHER.
This bold design makes an equally bold statement, and is a heck of a lot more fun than explaining to non-divers why your hair never looks the same after a dive trip. This design pairs well with our similarly designed CERTIFIED MOUTH BREATHER: MALE #2, which is a great match if you regularly dive with a male counterpart, but only if you want to acknowledge knowing that big lug who makes you carry your own tanks.
Why buy it? Because lady divers already know the score: you’ve traded lip gloss for salt crust, mascara for mask face, and still manage to look better than the guys at the rinse tank. This shirt is your unapologetic dive membership card—perfect for post-dive debriefings, boat deck selfies, or reminding land lubbers that yes, you really can breathe underwater. Why? Because you are a CERTIFIED MOUTH BREATHER!

There’s something unforgettable about drifting over a coral garden and spotting a flash of orange darting back into its exquisite backdrop of a home.
The Anemonefish Diver #2 tee captures that moment of delight every well-traveled diver knows well—a reminder that even the smallest residents of the reef can make a dive unforgettable. Bold colors, flowing lines, and that unmistakable little, curious fish give this design a playful edge, perfect for anyone who dives with equal parts curiosity, joy, and an urge to simply "clown" around.
Available in assorted colors and sizes for both men and women.
Coming Soon!
Certified Mouth Breather:
Bob Edition
Forget pranayama, belly breathing, and whatever your smartwatch says about “mindful inhalation.” You’re a scuba diver, which means you’ve perfected the noble skill of inhaling compressed air through a regulator with grace, poise, and past an influx of saltwater as you smile uncontrollably at depth. That’s right, you are a CERTIFIED MOUTH BREATHER.
This version celebrates divers who keep it short and smart—because if you rock a bob, we’ve got you covered. Whether it’s tucked under your hood or doing a jellyfish impersonation at depth, your hairstyle is a statement that you mean business: you came to dive, not to detangle.
Pair it with our long-haired CERTIFIED MOUTH BREATHER (Female #1) or our Male #2 edition for that perfect buddy-team match-up that is ideal for couples, dive buddies, or anyone who knows the rinse bucket is not a beauty salon.
Why buy it? Because divers with bobs know the truth: short hair doesn’t mean low maintenance, it means efficient hydrodynamics. You’ve traded blowouts for a streamlined profile. Wear it on your next liveaboard trip, beach cleanup, or after-dive burgers and beers—because you’ve earned it, Certified Mouth Breather.
