When the water’s black and visibility drops to zero, real divers earn their stories. The Nil Viz T-Shirt is a salute to those who thrive in conditions others can’t navigate. Crafted from a soft cotton-polyester blend with a relaxed fit, it’s designed for comfort on deck, at the pub, or wherever the tide takes you.
Featuring the iconic Siebe Gorman 12-bolt helmet with a dark, funky twist, this ocean-inspired tee captures the grit, humour, and heart of the diving life. Perfect as a gift for divers, adventure enthusiasts, or anyone who appreciates authentic Brass Hat spirit — both in their glass and their wardrobe.
When purchased individually, the Nil Viz T-Shirt comes in its own presentation box, ready to post through your letterbox — a thoughtful and effortless gift.
Wear the adventure, sip the spirit — pair your Brass Hat apparel with our small-batch rums for the perfect gift for divers, ocean enthusiasts, or anyone who loves adventure-inspired apparel.
