Bamboo bats are generally the most durable wood bats ever thanks to their tensile strength, which is greater than steel. The bat is BESR certified. The Maple Bamboo performs well in hot and cold weather. The bat is constructed with a core of bamboo and maple on the outside of the barrel. The maple resists denting and ball marks as well as strengthening the sweet spot. This product and more available at http://baseballtips.com/bamboo.html.
