Engineered with a blend of military grade Japanese Cordura and cotton, the 100 Year T Shirt is just as soft as a regular cotton t shirt, but its 14x stronger. The challenge for the 100 Year T Shirt was simple build a t shirt thats tough enough to outlive you, but comfortable enough for you to want to spend the rest of your life in. The reality of most t shirts is that after a few years they start to break down, then theyre thrown out. The 100 Year T Shirt is different. While it looks like a regular cotton t shirt and feels like a regular cotton t shirt, its made from a material so tough it was originally developed for military combat uniforms.
