Sierra says: The Trace is the perfect crossover helmet. So if you ride snow, skate, and bike this is the perfect helmet for you. The injected ABS shell will keep your head safe, while the removable ear pads and front vent plugs will keep you warm. R.E.D. says: Twice the stoke as the interchangeable Trace flows on snow and grinds summertime.

Sierra says: Go from mountain to mini-ramp in seconds with the Trace 0.5's easily changeable features. Burton's R.E.D. Trace Helmet is so light, you'll forget it's there. Full venting and easily removable features equal year-round skate, and snow and BMX comfort.
