Two wings, one current. The Aloha Mantas Long Sleeve features a pair of manta rays gliding through deep blue water, sunbeams streaking down from above and a faint island tribal pattern drifting behind them, with our signature lightning bolt glowing on the sandy seafloor below. It’s a graceful tribute to the quiet magic of a manta encounter, and to the warm-water dives that make it possible.

MY WORK UNIFORM
"These Grateful Diver UV shirts are pretty much my uniform. I'm a jet ski guide and am in the sun and on water all day so I need a lightweight shirt like this that looks good, dries fast, and adds some sun protection.

GRATEFUL DEAD MEETS GRATEFUL DIVER
Grateful Diver was created in 1995 when Grateful Dead co-founder and drummer Bill Kreutzmann, an avid diver, had the inspiration to design a Grateful Diver logo by placing the iconic Grateful Dead lightning bolt on a red dive flag. This iconic logo has raised money for marine conservation for almost 30 years.
