The most obvious reason to use round neck t-shirts as part of your business visibility strategy is that they're an incredibly practical way to spread your brand's name. Whenever someone wears a t-shirt with your logo or brand on it, they are literally advertising your company for you. Plus, if the printed t-shirt looks good, then you are already synonymous with quality before even being contacted directly. Even a simple cotton tee can do incredible things for your marketing strategy, by helping you to raise awareness.
