This is our first design that features the permit, one of the toughest species to convince to eat the fly. "Made For The Sun", a mantra we carefully consider every time we make a product, sits right in the front while an elusive permit resides high on the back. The MFTS Permit Long Sleeve T-Shirt fabric is notably lightweight with one flat side and one piled side. This boldly simple knit has good drape and softness characteristics. Our jersey knit also has some natural stretchiness. In general, jersey is an excellent choice for summer clothing as it won't weigh you down. It is also extremely flexible so it adapts to layering as the seasons change.
