An 11-year-old with autism founded his own business and invented a range of t-shirts for kids with sensory issues - selling more than 700 in their first release.br br Like others with autism, Max Palfrey struggles to wear regular t-shirts because he finds the materials "itchy" and the labels and seams irritating.br br He designed a super-soft top, without seams and labels, and with two hidden fidget poppers in the bottom hem for discreet self-regulation on-the-go.
