At just 850 grams, the Bell Sanction Full Face MTB Helmet is a low-profile full-face mountain bike helmet aimed at dirt shredders and BMX riders who don’t need the more robust Full-9 or Transfer-9. The Sanction has become the choice of adults who want full-face protection but prefer a smaller size and profile. If you’re riding a chairlift, go with a Full-9 or Transfer-9. But if you’re pedaling BMX or dirt jumps, this helmet will serve you well.
