For the young guns Weighing in at 950 grams, the Sanction is Bell"s fully-ventilated, low-profile helmet specifically designed with the younger rider in mind. Its sizing skews smaller than both its predecessor (the Bellistic) and the more robust Full-9 and Drop models. Though we originally envisioned the Sanction for youths, we see quite a few adults who want more coverage than an open-face trail lid choosing this helmet. If it fits you, we"re OK with that. But our rule-of-thumb is if you"re taking a chairlift, go with the Full-9 or Drop.if you"re pedaling - say super-D, BMX or Enduro - the Sanction should serve you well.
