The Authentic Logo T introduces a new look and feel into the true and tried HeadBlade line-up. Softer cotton and a more refined fit, the Authentic Logo T is a bit more restrained in its presentation. No logo or verbage on the back, just a medium sized logo on the front in a softer feel application. As they say; in with the new, out with the old. We like them both, but this is definitely the next level and rivals our Signature Series line of sweatshirts as 'most popular' attire in the HeadBlade offices.
