Built for First Basemen

First base is a high-demand position — you're receiving throws from every infielder, digging balls out of the dirt, and stretching for off-target throws all game long. The Acadia 37S1's deep pocket and Two Bar Post web create the structure and security needed to handle the volume. The 12.5-inch profile provides the surface area to make more plays, while the M Type fit system ensures the mitt stays locked to your hand through every aggressive stretch and pick.

The M Type Fit System

First basemen face unique demands — the mitt needs to stay in place during aggressive stretches and big scoops. The M Type fit system's integrated thumb and pinky sleeves with enhanced thumb stall cushioning deliver a personalized fit that gives you the confidence to go all-out on every play without fighting your equipment. It's the difference between a mitt you're wearing and a mitt you can trust.
