Every deep diver knows the rule of thumb: for every 33 feet you drop, it can feel like knocking back another drink on an empty stomach. Our "Martini's Law" Graphic Tee celebrates the ocean's funniest underwater phenomenon — nitrogen narcosis — with a sharp, minimalist design that speaks directly to the technical and recreational dive community.
Perfect for dive boat captains, divemasters, or anyone who loves a clever surface-interval icebreaker, this shirt lets everyone know you're a proud, law-abiding citizen of the deep.
• 100% ring-spun cotton
• Sport Grey is 90% ring-spun cotton, 10% polyester
• All Heather colors are 65% polyester, 35% cotton
• 4.5 oz/yd² (153 g/m²)
• Shoulder-to-shoulder taping
• Quarter-turned to avoid crease down the center
Note: The White color variant may appear off-white due to fabric properties.
