Wear a shirt that fits your exact body type with the 3 FIT Theory Ideal Fit T-Shirts. This line of apparel offers three different fits to help you find the one that is right for you. Suitable for all body types, 3 FIT Theory offers fits from “sizes” X-Small to 3XL (tall guys welcomed, too). In addition, the ideal fit t-shirts don’t shrink either. They also remain the same even after washing and drying them in the dryer with other clothes. To get started, each member receives three black, crew neck t-shirts to try on at home. Once you find your ideal fit, you unlock more colors including Military Green, White, Navy Blue, and Carbon. Offering lifetime membership, 3 FIT Theory includes prepaid return mailer so you can send back the shirts that don’t fit at no extra cost.
