Sanction Helmet

The Sanction is Bell's lightweight, low-profile full face helmet aimed at dirt shredders and BMX riders. It's lighter and sleeker than downhill race helmets like the Full-9 or Transfer-9, but still has a robust ABS shell and EVA foam padding to absorb impacts in a crash. A moto-inspired mouth guard extends the shell to protect your face if you go over the bars, and 15 ventilation ports keep your head cool when you're ripping pump tracks or sessioning your local dirt jumps.

  • Lightweight full face for riders wanting low-profile protection
  • Smaller size and lower weight than most downhill race helmets
  • Tough ABS shell and EVA impact foam protect your head from impacts
  • 15 vents to provide cooling airflow on summer shred days
  • Adjustable visor that works well with goggles

Fit is an Issue

    I ordered the large which is a big as they come in, and while the helmet fit my head just fine, it was WAY to small in the jaw/face area. It pushed in so hard on my jawline that it very quickly became uncomfortable and unusable. It's a shame it did not fit, looks like a nice helmet. But when you read that it "fits slightly small" it's more like "fit's very small." Just know that when ordering. Take your measurements and then up-size one if available. Otherwise, it will squish your face.


    • Fit: True to size
    • Size Bought: LG

    price is right and fits just right. always get good feed back from other riders and people hiking on the trails

    Bell Sanction

    • Familiarity: I've used it several times

    Great helmet! Super light weight & very comfortable, make sure to order 1 size up from most other brands.

    Unanswered Question

    Is the Bell Sanction helmet sized for juniors?

    Buy 1 size up!!

      Great helmet, my head is 22in in circumference and instead of buying the medium, I bought the large. The large fits nice and snug, but not too tight!

      Security blanket

      • Fit: Runs small
      • Size Bought: large

      The large helmet was snug but fit. I've used it a few times, but it gets too warm causing my neck to sweat when on for more than an hour on days over 75 deg. F. I feel safer road biking with this helmet compared to a light weight cap style helmet.

      Great Helmet

        I love this Helmet! I am a girl with a small head and I needed a medium so make sure to size up. It's very sturdy and comfortable. Great helmet!

        sizes are too small

        • Familiarity: I returned this product before using it

        Caution, the size charts may not be accurate (unless my problem was general head shape or something, but I think my head's pretty normal!) - I got the medium, and size chart put my head circumference dead center in the middle of their "medium" measurement - but it was WAY too tight,especially at the cheek area. So I am now returning it, hoping the large will do the trick and not be too loose or something....

        Unanswered Question

        i wanted to know about the size, if fit true to the size? or is smaller?
        i'm normally M but i never use a full face helmet and what i tried so far Medium was my size...
        thank you

        Better than Ezra

          This is a helmet! It is a lid worthy of an ANSI test and not a throw away foam bucket that gets tossed to the side of the road when the EMTs load the gurney. No they will have to cut this one off at the emergency room with a rotosaw granted someone finds you unconscious on the side of the trail someday after colliding with a tree. This helmet is strong and will saw your head so if you do hit a tree you may be able to ride it back to the car

          Definitely not just for the groms

            I bought this as a park and DJ helmet but it ended up being so comfortable that it's a go-to now.

            best deal

            • Familiarity: I've put it through the wringer
            • Fit: True to size

            just right for the price and fits just right. bell helmet is good brand

            Perfect Helmet For The Kids

            • Familiarity: I've put it through the wringer

            I've been taking my kids to the bike park and trail riding more and they are getting more aggressive. My 7 year old took a bad fall to the face and I decided he needed a full face. This helmet is super light and not too hot. I got the small and it fits my 7 year old and 4 year old sons.

            Perfect Helmet For The Kids


              Great size, fits well and very light. I haven't taken in out yet but it fits great and the goggles sit in there just perfect. Great for the price.

              Great Dome Protector

              • Familiarity: I've used it several times

              Lightweight and fits great. Prefer the quick release buckle. Minor detail, but liked that it came in flat black.

              Great Helmet for the price!


              • Familiarity: I've put it through the wringer

              Super light- as light as my buddies carbon, or lighter.

              Super comfy- seems true to size

              The buckle strap may not be as strong as a friction loop thing, but it's 10x's easier. pretty rare that i'll crash and test the buckle strength though.
