• Stay positive shark tee: a grinning snorkel boy gives a thumbs up as a huge shark bursts from the waves behind him, for dark humour fans and beach days
• Sizes S to 5XL, unisex fit, in many colours
• Material: 100% cotton across three qualities; Standard Gildan 5000 is the everyday midweight, Heavyweight Comfort Colors 1717 is thicker with a washed feel, Premium Bella Canvas 3001 is the lightest and softest; heathers are blends
• Printing: with DTG the ink soaks into the shirt itself, so you cannot feel the design; with DTF it is pressed on as a thin layer, so the retro colours stay bright on a dark shirt
• Wash inside out in cold water and tumble dry low

Optimism, whatever the odds.
