Custom First Base Mitt – Pro-Grade Design

The First Base Mitt You Build, Not the One You Settle For

First base is deceptively demanding. Scoop low throws. Stretch to the long throw. Secure the high throw over your head without losing sight of the runner. Every action has a specific shape, and a compromise mitt — which is what retail usually sells — makes every action slightly harder than it needs to be.

Kachi's custom first base mitt is built to the specs that first basemen at the college and pro level actually ask for. Extended reach, deeper-than-average pocket for secure scoops, Japanese Kip leather for weight savings that matter when you're extended for a full 9 innings.

Why Not a Retail First Base Mitt?

Rawlings, Wilson, and Mizuno all make good first base mitts. They're also built to a general-market spec — a compromise between youth fits and adult hands, between the short-throw scoops and the stretched-out catches. Kachi builds yours to your actual hand size, your actual reach, your actual league.
