Do I need a full-face helmet for dirt jumping?

It depends on the size of the jumps and your skill level. For small to medium dirt jumps and skatepark riding, a standard BMX helmet provides adequate protection. For large dirt jumps (over 10 feet of air), step-up jumps, or if you're learning tricks with high consequences, a full-face helmet provides additional jaw and face protection that could prevent serious injury. Some riders use a BMX helmet for practice and a full-face for competition or when attempting new tricks on large jumps.
