From MLB.com:

A new titanium mask engineered and crafted by Nike, which is as light as a feather but is 10 times stronger than steel. The rods are smaller to help catchers see through better and the durability is, according to Posada, endless. ...

Posada has gone to the Nike headquarters in Portland, Ore., during the offseason the past two years to give suggestions and to listen to new ideas from the engineering team. He has worked specifically with the Nike Sport Research Lab (NSRL) to figure out ways to improve everything from chest protectors to cleats.

The NSRL is a state-of-the-art center where designers are devoted to bringing products to the market that take athletic performance beyond the next level. The lab works with professional athletes in every arena to develop and test the newest in sport technology. ...

Posada will also go to battle this year with a new type of chest protector that has padding that is smaller and lighter but also stronger and more durable than in the past. It also is created of microfibers that pull the sweat away from the body, keeping the catcher dry during the hot days of summer.
