Iconic MK-5 T-Shirt - Maroon

$40.00

Maroon runs deep — and so does the story behind this tee.

The MK-5 helmet at the center of this design is a nod to the hardhat divers who pioneered the deep, surrounded by an umbilical line that represents the lifeline between diver and surface. A north star sits above it all — the same one that's guided sailors and divers home for centuries.

This colorway isn't subtle. Maroon commands attention the same way a diver commands the water — with confidence, purpose, and a little edge. Wear it as a statement of who you are and where you come from.

  • CVC Tee — 60/40 combed ring-spun cotton/polyester blend
  • Lightweight 4.3 oz premium fabric
  • Pre-laundered for reduced shrinkage
  • Modern athletic fit
  • Bold MK-5 helmet graphic with umbilical and north star design
  • For dive enthusiasts, veterans, and ocean lovers

Wasn’t skeptical at all about these shirts. I’ve seen too many people with them and felt left out, so I picked up 3 of my own. My expectations were passed - no surprise. These shirts deliver. Super soft, super light and an overall great fit!

Just right

This shirt is just what I was hoping for. The design is very defined and appears that it will survive many washings. The fit is just right, the maroon color is really nice, and the material is very light and comfortable. Great product with equally great customer service.

Didn't receive order

We actually never recieved this shirt in the mail. I had it sent to my parents house in Texas. Is there anyway we can figure out how to send it again, or get a refund please?
