Lightweight Sturdy Construction

Bell Sanction Adult Full Face Bike Helmet uses the sturdy and lightweight ABS Hard Plastic shell design. It is a modern, durable material that is not bulky on your head. Instead, its low-profile style looks like the standard cycling helmet. And, its high luster paint finish keeps the color themes shining for long, regardless of the exposure to harsh sunshine.

Narrow Fit, Wider Size Options

Do you have petite or oval facial features? If so, finding a helmet with a snug fit can be challenging. Well, the Bell Sanction Adult Full Face Bike Helmet seeks to address this.

First, it retails in a narrow construction that feels firm on the sides. Plus, it has convenient cheek pads that guarantee a comfortable, sweat-free fit. Here, if you have regular facial features, we recommend picking at least one size bigger. 

Second, there is an X-small helmet size catering for riders with a 49 cm head circumference. And its broadest size suits a head circumference of up to 60 cm. This way, the helmet is appropriate for kids and adults of both sexes.

Optimal Ventilation

There are 15 strategic ports all around the Bell Sanction Adult Full Face Bike Helmet. These vents allow for air channeling into and out of the helmet for a dry, refreshing ride. Their localized heat transfer mechanism prevents the MTB riders from overheating. And, as a budget helmet, the design of the vents further improves the structural integrity of the ABS hard shell.

Detachable Visor 

Now, a visor is essential when it comes to dirt jumps or riders on single narrow tracks. You know extreme stunts can result in loss of teeth or nasty cuts to the face and eyes.  And, low hanging tree branches on single narrow tracks can hurt your face or make you lose your balance.

Bell Sanction Adult Full Face helmet opts for a detachable visor with an anti-fog, scratch-resistant finish. This removable shield on the ABS shell guards your face and eyes against dirt and sand. The design can withstand harsh handling by extreme riders. 

Likewise, the visor protects the riders’ eyes from direct sun glare, flying objects, or strong winds. Hence, no more stretching out one hand to clear low-hanging branches while moving at top speeds. Instead, enjoy unrestricted visibility on a hot or foggy trail. 

As a removable unit, you can detach it from the helmet when you don’t need it. And, in the event of a collision or a fall, this visor snaps off the helmet, minimizing further injuries. 

Permanent Chin Bar

Bell Sanction Adult Full Face Bike Helmet uses a permanent chin bar for the ultimate jaw protection. It is a plus for MTB riders prone to hitting their jaws during major impacts. 

Quick-Release Buckle Chin Strap

Bell Sanction Adult Full Face helmet uses an adjustable buckle chin strap that stays put as you tackle your extreme stunts. It is a simplistic quick release mechanism for a secure fit. Besides, you can easily adjust the straps with or without wearing your gloves.

4 thoughts on “Bell Sanction Adult Full Face Bike Helmet Review”

  1. Thank you for a very interesting article. I was just looking for a good BMX helmet, but it is not easy to choose with so many options on the market. But looking at your review, Bell product is what I’m looking for. It guarantees safety, and I like the design, and the price is really reasonable. I am looking forward to testing it in practice.

    • Hi, Cogito, and thank you.

      Thank you for your kind words.

      I believe you would like to see this post about many good helmets for both genders.

      Great to hear about your benefit of the article too.

      Don’t hesitate to contact me to help you with anything else or if you have any questions.

  2. I think the best features of the O’Neal helmet are the detachable liners and the magnetic buckle. My 3 sons get super sweaty when out bike riding, so the ability to remove the liner and throw it in the washing machine. I didn’t see any liner information for the Bell Sanction helmet, but I would assume it has something similar.

    • Hi, Kelly Smith, and thank you.

      Thank you for your kind words.

      Yes. The Bell Sanction has similar.

      Don’t hesitate to contact me to help you with anything else or if you have any questions.
