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 a Full 9 or Drop..if you're pedaling say Super D, BMX or Enduro the Sanction should serve you well.
