  • In-mold helmet construction bonds a flyweight shell to a high-performance expanded polystyrene foam liner for excellent protection and low weight
  • Ventilation channels on the interior of the helmet's liner bring cool air in through the front, pass it over the head and flush warm air out of the rear ports
  • The easily-accessible Speed Dial fit system adjusts to a glovelike fit with a simple twist of the dial
  • Cam-lock strap levers make it easy to adjust the straps around your ears: simply open the cam, position comfortably and close the lever for a secure fit
  • Coolmax® padding moves perspiration away from the head, where it evaporates quickly, allowing the rider to feel cooler and more comfortable
  • The Bell Stoker Bike Helmet for men features a visor for extra protection; goggles compatible

Rated 5 out of 5 by from Excellent fit This helmet replaces a Giro that I've used for many years. I've never cared for the way the Giro sat high on my head and I've never felt that it fit securely (could be my fault). The Stoker was easy to fit to my head and it feels much more secure. I also like the additional protection the Stoker offers for the back of my head. Overall there seems to be more of the helmet in contact with my skull than I had with the Giro. The visor on the Stoker also provides better protection at low sun angles during early morning rides. Highly recommended.

Rated 4 out of 5 by from Comfortable I purchased this helmet about 8 months ago as an upgrade to my very old BMX race helmet. The adjustment wheel on this works extremely well for customizing fit quickly and easily. The vent holes provide enough airflow for me to stay fairly comfortable and avoid fogging my glasses in hot weather, and I've found they do not make me unnecessarily cold during the winter. I would have liked an option to mount a blinky light on the back for improved nighttime visibility when riding with traffic aside from looping a zip tie through the rear vent holes, so I just affixed some SOLAS reflective tape.

Rated 5 out of 5 by from LOVE THIS HELMET Searched around a lot for a truly comfortable MTB helmet that I wouldn't be fidgeting with on the trail. This Helmet in a Mens Small fits my cranium just perfect. Super comfy pads and straps. I forget I have it on! Highly recommend it.

Rated 4 out of 5 by from Great Helmet When a Full Faced Helmet is not required this fits the job for those All Mountain adventures; even fits biking googles. It feels very much like my XC helmet, I may just shelve my XC Helmet for this added protection. Ease of adjustment for cold weather riding with an insulated skull cap.

Rated 5 out of 5 by from First REI purchase I've been riding for about a year. This was a great first purchase at REI. Best light weight helmet I've ever had, with a nice color. The adjustment is a little bulky, but you shouldn't need to do it often. Great buy. I ride on MT trails mostly, and the lower head protection is nice.

Rated 5 out of 5 by from NIce helmet This is a good all around helmet. I use it for commuting, road riding and off road. It has fewer vents than traditional helmets but it has not been a problem so far. It looks fairly decent and it fits nice. I'd recommend it.

Rated 4 out of 5 by from solid brain bucket good helmet. The speed dial fit is especially nice. The helmet fits well in warm weather and can be adjusted for the cold weather when wearing a beanie style hat under the helmet. I bought the matte black, but added some reflective stickers. Simple, unobtrusive, lightweight with good ventilation. The speed dial makes sure that the helmet doesn't bobble around while you ride.

Rated 4 out of 5 by from Excellent helmet that will last for time I use this helmet when I ride to the gym and trail riding which makes it an all around good choice.
