Mandelbaum Gym Performance Hoodie

Any real Seinfeld fan knows about Mandelbaum Gym, Izzy Mandelbaum, and the phrase It’s Go Time. We first met Izzy in Season 8, Episode 17 of Seinfeld, The English Patient. This shirt design reminds us of Izzy strapping on his boxing gloves in Jerry Seinfeld’s first training session.  It's Go Time! 👕 50% cotton / 50% polyester 👕 Dri-Power® Moisture Wicking Technology 👕 Russell R logo flagtag on left hem 👕 Double-ply hood with drawcord, Set-in sleeves, Front pouch pocket & Rib-knit cuffs/bottom band
