ADULT 30-DAY WARRANTY BATS Adult model BamBooBat baseball bats are made with the highest quality bamboo available. We use a proprietary mix of various bamboo, to create a durable and weight-appropriate bat for players 13 years old to adult. Our adult bats come in sizes from 29"" to 34"" with one-inch increments in between. The durability and performance that our bats provide make them the best value for the dollar in the industry. BamBooBat baseball bats are much stronger than the traditional ash or maple baseball bats found on the market today.Players who have never used a wooden bat before, don't understand the difference in using a wood bat compared to using a composite bat. Many players break traditional wooden bats regularly, so the added durability of the BamBooBat allows players to hit with more confidence. Unlike regular wood bats, this model BamBooBat come with a 30-Day Warranty against breakage from the time of purchase.
