Features

  • One-Piece Bike Helmet Construction: Extremus cycling helmets adopts a one-piece construction with a shock-absorbing PC material outer shell and EPS inner foam (made in the USA). Its crafted design is not glued together like other MTB bike helmets, and the external shell fully covers the EPS foam, which ensures a longer-lasting durable yet safer structure. This safety technology is lightweight yet super tough and provides all-around protection for your head while riding.
  • Quick Dry Cooling System & Shock Shield Technology: Our bike helmets for adults has a specially designed Quick Dry Cooling System and Shock Shield Technology to provide extra comfort and maximum protection for your head. The soft liner combines mesh pads with sponge material that improves comfort while also absorbing sweat and cooling your head. And the Shock Shield Technology has a specially engineered silicone cushion that provides enhanced full-spectrum shock absorption in collisions.
  • 16+3 Aerodynamic Ventilation System: This bicycle helmet has a unique mold design that contains 16 aerodynamic 3D vents and 3 extra vents on the forehead section. This streamlined construction maximizes airflow, prevents overheating, and increases aerodynamic efficiency while also ensuring security. The road bike helmets includes a padded adjustable chin strap for a safer and smoother ride.
  • Size Adjustable Dial + Safety Lights: Our road bike helmets for men and women has a convenient size adjustable dial: using one hand, turn the dial on the back of the helmet to adapt the built-in helmet framework for a perfect fit. The integrated dial includes a red rear safety light that has three lighting modes: slow flash indicator, fast flash SOS, and normal night mode. With one-hand adjustability, you dont need to remove the helmet to tighten the fit or change the light.
  • Multifunctional Design Bicycle Helmet: This mountain bike helmet includes a thick detachable sun visor that extends twice as long as other helmets, which provides you more sunshade and extra protection during riding from overhead branches. Simply snap on the visor to lock into place, or detach and store the visor when not needed.The soft protective interior liners are also removable for hand washing in between rides.Perfect for cycling, biking, skateboarding, rollerblading, or scootering.

  • Great Helmet for MTBing
Color: Stryker Green Size: M/L( 23-24in/58-61CM)
I have a good helmet for my road bike but it has a mirror permanently attached on the left side. I find that it sometimes catches branches, when I am on my MTB bike. I have purchased some other extremus products (cooler, travel mug, ski bag and sunglasses) and the quality has been great. So I ordered this and it did not disappoint. Comfortable, easy to adjust, removable sun visor and a great price point. Would buy again. ... show more

  • Very comfortable
Color: Fluorescent Green Size: S/M(21.3-22.8in/54-58CM)
It was important to me to have a hard brim, because as a first responder I've seen how a hard brim can help protect the nose in a crash. I like that it has that feature and is comfortable.

  • New vs old
Color: Stryker Green Size: M/L( 23-24in/58-61CM)
Short and sweet review. In the picture the new helmet to the left and the old helmet to the right. As the old one had plenty of use but never felt just quite right so in came this new one. Initial reactions are good, it's sturdy, comfortable, and the little light is a nice touch. Not had a solid ride to govern it's feel after a hour or so. Things can feel different once your out and about but I'm hopeful. Color option matched up well with my bike. All in all as it was caught on sale for 40 bucks and arrived pronto so that's a win no doubt. ... show more

  • Comfortable sturdy
Color: Stryker Green Size: S/M(21.3-22.8in/54-58CM)
I haven't had a chance, thankfully, to see if it prevents major head injuries. But I know it's sturdy and seems to be well padded. The light on the back is great. Fits my head well. I have a tiny head for an adult and it is snug. Very comfortable

  • Nice quality, perfectly fine helmet.
Color: Stryker Green Size: M/L( 23-24in/58-61CM)
I paid $30, and am perfectly satisfied, it's nicer than the department store helmets in the same price range, I looked at those first and was just going to buy one the next time I needed groceries, and figured I may as well check on Amazon.

  • safety features (rear lights on helmet)
Color: Bluish Grey Size: M/L( 23-24in/58-61CM)
Loved it. My old helmet had seen better days (no crashes but replacement was recommended). Easy to assemble and fits well. Great value.

  • Comfortable bike helmet
Color: Fluorescent Green Size: M/L( 23-24in/58-61CM)
I really like this bike helmet because it is more comfortable than the several other helmets I tried. The bright yellow green stands out and makes you visible to other bikers. I’ve had a lot of compliments on this helmet. The flashing light on the back of the helmet is a nice safety feature.

  • Keeps falling forward
Color: Stryker Green Size: M/L( 23-24in/58-61CM)
No matter what I do with the straps, it keeps falling forward. It's so annoying. I had to take of the front visor part because it kept blocking my view.
