5 T Shirt Niches Nobody's Talking About

About this video

Martinez presents five simple, low-competition niches he says can sell all year, aimed at POD beginners and sellers busy with Q4, giving the niche, the competition count and a design prompt for each, and reminding viewers to always double-check trademarks and copyrights. He says he mixes Amazon, Etsy, social media and other tools, and uses Ideogram AI and ChatGPT to generate the example images, recommending Kittl to upscale and remove backgrounds. The niches are: ‘The official sleep shirt’ with a cute animal on a pillow (242 results), positioned as a big pajama shirt for the holidays, and scalable by swapping the animal, e.g. to a baby panda; ‘I love dad tattoos’ featuring a dog (93 results), scalable across dog breeds and to ‘I love mom’ variants and Father’s Day angles; ‘Wild floral horses’ (322 results, $19.97 on the example), where he points to repeated BSR drops over the last 30 days as evidence of multiple sales; ‘I love my bass player’ (138 results), a simple text-and-heart style he says could generate over a hundred designs across band roles, with variants like ‘bassist’ and ‘my heart belongs to a bass player / drummer’; and ‘Med tech life’ (191 results), aimed at the medical field ahead of Valentine’s Day appreciation. He also promotes his Top Research Design Vault at $10 a month, saying it gives access to over 1,600 already-researched niches plus 20 new niches every week with keywords, design angles and prompt ideas.

Key takeaways

• Always double-check trademarks and copyrights yourself, even when a niche is presented as researched
• ‘Official sleep shirt’ animal designs (242 results) scale by swapping the animal — the video demonstrates changing the prompt to a baby panda in seconds in Ideogram AI
• Very low competition exists in specific pet phrases: ‘I love dad tattoos’ with a dog had only 93 results and can extend across breeds and to mom variants
• Synonyms create new listings: ‘bass player’ vs ‘bassist’ and ‘my heart belongs to a bass player’ are treated as separate design opportunities (138 results for the bass player search)
• Use Kittl to upscale AI images and remove backgrounds before upload, rather than relying only on Ideogram’s built-in tools
