The Sirianni Snapback (All Black)

Sizing guide

Introducing the Sirianni Snapback, inspired by Eagles head coach Nick Sirianni, the man who made our original Snapback famous by literally never taking it off. During a recent conversation with Jason Kelce on the New Heights Podcast, Coach Sirianni requested that we make another version of the hat, this time in all-black. "For you, coach? Anything."

This all-black, mesh-back trucker hat will become a faithful additional to your daily gear. Built on the extremely durable Flexfit 110® platform, this retro-inspired 6-panel design features a buckram front panel and visor, a super breathable mesh back (made from recycled plastic bottles), a snapback closure, and an elastic band that adapts to you. Best of all, this hat is custom embroidered with the Underdog logomark on the front as well as the wordmark on the back.
