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.

  • GOOD HELMET BUT THE VISOR WAS BROKE/UNABLE TO ATTACH
Color: Gray Size: M/L( 23-24in/58-61CM)
STURDY, COMFORTABLE AND GOOD VALUE. COMPANY NEEDS TO REVISE THE HELMETS VISOR DESIGN BECAUSE MINE WAS NOT ABLE TO ATTACH AND CAME LOOSE/OFF DURING A SPEEDY CYCLE RUN. THAT WAS A TAD DANGEROUS AS IT OBSTRUCTED MY VIEW TEMPERARELY. GOOD THING I HAVE QUICK REFLEXES TO STOP AND ADJUST. WOOD GLUE RIGGED IT INTO PLACE BUT FOR WHAT I PAID. IT SHOULD HAVE BEEN DESIGNED BETTER TO ATTACH. :( ... show more

  • Ok bike helmet
Color: Fluorescent Green Size: M/L( 23-24in/58-61CM)
Nothing fancy or stylish about this bike helmet. About average quality for helmet at this price. Color is very bright for safety purposes/vehicles to see from a distance.

  • New vs old
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

  • Great Helmet for MTBing
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

  • Keeps falling forward
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.

  • 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.
