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
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

Husband likes it. Said it’s comfortable and his head doesn’t get hot. Also like the visor aspect.

  • Looks and feels good, adjusts easily
Color: Navy Blue Size: S/M(21.3-22.8in/54-58CM)
Some reviews mentioned some trouble attaching the visor, but we had no trouble after following the advice to put the center pin in first. Have to say that the pieces don't line up absolutely perfectly but it is nothing you would notice. The visor is longer than the one on most helmets, which is great for keeping the sun out of your eyes. It also looks good. The helmet contains lots of air vents, which is great, and the vents are not just holes but contain netting which will keep bugs out. You can make the helmet looser or tighter simply by twisting the knob which is also a light in the back. This is very convenient. What is not convenient is that the space between the back bottom of the helmet and the light is not large enough to get hair through to keep it off your neck, and the light is far down enough that you have to use a very skinny rubber band in order to make a ponytail under it, and that ponytail may be slightly lower than you would like. The helmet is not shiny, whereas most bicycles are, so this helmet is not likely to completely match your bicycle. That said, it is advertised as matte, or not shiny, and the advantage to that is that the person riding behind you will not suffer from glare from your helmet. The important thing is that you don't notice it once it's on and it keeps you safe. ... show more

  • 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

  • Ok bike helmet
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.
