Item # BEL0027



Bell's Sanction Full-Face Helmet was originally designed as a lightweight domepiece for the groms, but it proved so popular that Bell sized it up to suit dirt-jumping, BMX-riding adults. It's lighter and sleeker than full-faces meant for gravity riding but has a hard-laminated fiberglass shell and EVA foam padding to absorb impacts. A moto-inspired mouth guard extends the shell and channeled ventilation helps keep your noggin cool when you're ripping pump tracks or dialing in your tail whips.

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

          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.

            great helmet

            • Familiarity: I've used it several times

            Great helmet no regrets I love the buckle strap instead of having to weave it through.

            for the price I would totally choose this over the other cheap full face helmets.

            Awesome helmet, Awesome price

              This helmet is amazing for the price! Although it does get a little hot, its not that bad. I got red and black one, and its one of the sweetest helments ive ever seen

              Good Deal, Looks Great!

                Great helmet. I have tried on many and the other helmet brands just don't fit my head right. I pretty much only wear this when I'm doing hard core stuff, but I have it in my equipment bag and bring it with me everytime I go riding. THat way I have it on hand if I'm feeling daring. I also use it for night riding and if it is really windy or nasty outside. It does get a little hot after extended climbs... but it's not really intended for that.

                Good Deal, Looks Great!

                First Full Face Helmet

                  I was very pleased with this helmet. The construction is fantastic for the price. I briefly owned another full face helmet I bought from Hn'R, a much more expensive one and returned it due to weight and lack of good ventilation.
                  This helmet is actually so lightweight, I almost forgot it was there. Never felt like my head was being weighed down.
                  The ventilation is also something that surprised me. with 15 vents, the airflow feels great when you're riding, and never felt too hot.
                  The Large size is quite snug on my 59cm dome, and I could see people with larger heads finding it too tight.
                  Overall, for the price, this is one great helmet. I would highly recommend it as a first full face helmet or replacement for an old one.
