  • Offers safety; easy to fit & comfortable to wear

This is a good helmet! It's comfortable & easy to use, fit, & adjust. I love that it has a light for being seen. It's a nice color & a reasonable price. Finally, I feel that it offers a good level of safety & I'm going to dispose of our old helmets. It is lightweight & has ventilation. This new helmet is SO much nicer than the old helmets! ... show more

  • Great Safety Helmet!!!
Color: Matte Stone Size: One Size Style: Helmet
Well, I purchased my first ever electric scooter (at 74) that has a seat and rear basket from Amazon and in the product manual it states to use safety gear. Well, I only travel 1/2 mile round trips to work so I ignored that warning; the result was I took a hard fall and bruised my ribs; banged my knee; scraped my elbow and yes, banged my head on the sidewalk. That was a hard lesson learned !!! So this was one of the safety items I purchased. The helmet is solid! It’s a one size fits all so I’m not sure what to say about that. I do know that out of the box it fits me perfectly; a little tight but I prefer it that way. I really like the added safety light in the back of the helmet. Lights really well for when I leave work at midnight. Not sure how to change the battery, when needed, but I’ll worry about that when the time comes. I guess my only gripe is that rain visor on the front of the helmet; it comes off easily but that is actually my fault because I store it in my old backpack that is secured to the rear basket which is probably a little bit too tight for my helmet. But, at work I have to store it or everyone will play with the helmet and light. This is definitely a 5-star product!!! Well constructed; great added safety feature with the rear helmet light; solid straps; comfortable! ... show more

  • A STYLIN BRAIN BUCKET
Color: Matte Black Size: One Size Style: Helmet
Take a load off. This helmet is so light you forget you're wearing it the second you snap the chin strap, With the many vents the air flow is so coool around your dome you'd think it had AC. Nice touches everywhere. First and foremost the padding is plenty tuff and gives peace of mind,( literally), that it will keep your coconut protected. There are two reflective tabs at back that blast and oh yeah, a fantastic triangular light for a day or night heads up for the traffic behind you. 3 settings - straight - blink and my fave a circular pattern. When my Lennon helmet came the light had a glitch. Worried about customer service with Retrospec? Fuggedaboudt it. I emailed the their guy and had new light in 3 days. My only quibb is it is very difficult to pull the light off the helmet with your fingers to (some day) change the long lasting flat battery. Solved that prob with my fave tool, a butter knife. I live in area with steep hills. Around sundown the pitch points you eyes directly into the sun. The small visor gives a surprising amount of shading. It is also priced around at a mind blowing 40 bucks. Last but not least, it's got a stylin look. No easy feat with a bike helmet. Props Retrospec. ... show more

  • Tight Fit

  • Sleek, modern, tight fit
Color: Matte Black Size: One Size Style: Helmet
The media could not be loaded. Love this bike,! Purchased it to remain safe while riding my bike on main roads through our town. Love that there is a feature of the LED light on the back to provide extra caution and safety when riding my bike. The helmet is a very comfortable, I love that it adjust with the knob on the back to provide extra comfort and ensure that the helmet fits tight enough to my head. We live in sunny Colorado and I can get pretty warm going on long bike rides, there are holes in the helmet that allow for airflows so that you do not get extra sweaty and have matted bike helmet hair for the rest of the day. That helmet is versatile, It could be shared between people with different head sizes due to the adjustability, and the look can change- the sunvisor can come on and off to give you a different look, the light can be turned on or off on the back. It procides great protection and performs, as I would expect, great value for what you were getting in this product, much cheaper than other bike stores sell it for yet provides the protection needed! ... show more

  • Perfect helmet for the price.
Color: Matte Black Size: One Size Style: Helmet
I have been using this helmet for over 6 months now and its been fantastic. The padding and build quality are excellent, and it has held up really well using it multiple times a week. It also has excellent ventilation, and I feel like my head sweats a lot less in this helmet than previous ones I have owned. I have been lucky enough not to crash to fully test it out, but based on the overall quality, I am certain it is very safe and will perform well. The battery life on the rear light of this helmet is also excellent, and the red lights are very bright. They have performed well when riding at night. This is a great helmet for the price and also looks awesome! Grab this one! ... show more
