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.

Designed by pitchers. Tested in Miami.
Kachi was started by two former MLB pitchers — Julio Teherán, two-time All-Star with six consecutive Opening Day starts for the Atlanta Braves (tied with Warren Spahn), and Carlos Castillo, who pitched for the White Sox and Red Sox across an 18-season career that took him through Japan’s NPB and Taiwan’s CPBL — the leagues where Japanese Kip leather is the professional standard.
Every Kachi pattern is field-tested at Kachi Baseball, Carlos’s training academy in Miami, before it goes into production. Built with Japanese Kip — 30% lighter and roughly 2× stronger than steerhide. Free heritage-flag embroidery for every Latin & Caribbean baseball nation. Lifetime craftsmanship guarantee.
