Capture the spirit of the 1940s with this Vintage BYU Sailor Mascot Sweatshirt. The design showcases BYU Cougars' iconic mascot, Cosmo the Cougar, donning a classic sailor hat. This nostalgic piece salutes BYU's sports history, setting a trend for sports apparel lovers. Originally introduced in 1953, Cosmo has been the heart and soul of Brigham Young University and its teams. This sweatshirt pays homage to a previous version of Cosmo, reflecting the buoyant ambience of the school's Provo campus. It's more than a sweatshirt, it's a piece of BYU sporting heritage. Embrace the vintage, appreciate the journey.
