The MK-5 is more than a helmet — it's a symbol.

For generations of Navy Divers and commercial divers, the Mark-5 diving helmet represented the pinnacle of underwater work. Heavy, unforgiving, and built for the deep — it demanded respect. This hat carries that same energy topside.

The 15 Fathoms Mark-5 Hat features our iconic MK-5 woven patch front and center, a breathable mesh back panel for all-day wear, and an adjustable snapback closure that fits any head size. Whether you're on the water, at the dock, or just repping the dive life on dry land, this cap holds its own.

Built for those who know what it means to go deep.

Iconic MK-5 woven patch on front panel
Flexfit blank — premium comfort and structure
Breathable mesh back for all-day wear
Adjustable snapback — one size fits all
Assembled in California
Perfect for divers, veterans, and ocean enthusiasts

I love this hat more than I ever knew was possible. I never liked snapbacks until I wore this and I now own 5 of them! My wife also loves the classic shirt!

Great Hat!

As a career research diver, I have been looking for a cool "DIVE" related brand that represented the lifestyle. Found it!! What is cooler than the old school hard hat dive helmet? Nothing! I have been wearing this hat almost every day since it showed up! Keep up the great work Thomas!
