The NEC Moon Mammoths Replica 39THIRTY brings authentic ballpark style to your everyday lineup. This stretch-fit cap is similar to the design worn by players on the field, featuring the iconic Moon Mammoths wordmark embroidered across the back. The structured 39THIRTY fit delivers all-day comfort and a classic baseball look that works whether you're cheering from the stands or repping your team around town.

The Moon Mammoths brand is a creation of Last Week Tonight with John Oliver, in partnership with Major League Baseball and the Erie SeaWolves.
