Worn by serious downhill racers and dirt jumpers with an appetite for going big, the Leatt DBX 4. 5 Neck Brace allows you to focus on shaving time off downhill runs and expanding your bag of tricks without wrecking your neck in the process. Its fiberglass reinforced nylon construction protects you from impact, and the injected foam padding allows for a comfortable fit over your shoulders, while softening impact from costly downhill crashes and jump mishaps. Its two way adjustable design provides a near custom fit, provided you've selected the proper size for your upper body dimensions. Moreover, you'll find an emergency release for easy removal, should friends or medics need to pop this sucker off in the event of a serious crash.
