Why Birch? Swinging Birch feels like a perfect blend of Ash and Maple. It makes the most durable wood bat. It has flex which allows the ball to jump off the bat. It strengthens over time unlike Ash and Maple. We find our Birch bats to have as much pop as ever even after multiple years of heavy game/practice use. Birch is a great choice for veteran hitters and even those swinging wood for the first time.
