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!

Perfect helmet for the price.
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!

Not quite black
Overall the helmet is okay. Safety is the most important thing, and I am confident it will do its job well, and it fits good, secure, comfortably. I ordered black but in the sunlight, (which is where I will wear it hopefully) it appears to be very dark blue... not quite black. Also the LED light was a pain to get out. It says no tools required but I had to get out a flat head screw driver, and it felt like the plastic tabs were going to break before it popped out. As you can see from my photo, I think maybe the light wedges too deep into the helmet on the left side. It took a lot of prying and it scuffed up the back of the helmet.

Great product great fit great price
Great fit.. nice safety light on the back. Adjustable tightness to your head. I'm glad I picked this one out of all the choices I could have made

Quality Helmet, too small for petite female.
Helmet is good quality, looked really nice on me and was comfortable. Unfortunately my head is slightly under 54cm and had a bit of wiggle room so I have to find another helmet which is a bummer. Would recommend though if your head is 54cm exact or over.

A STYLIN BRAIN BUCKET
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.

Breathable, Visible, & Pretty!
Pretty, light weight, functional, and most importantly breathable. My climate gets super hot and humid. This helmet allows for plenty of airflow. The reflectors and led lights are visible. I have a large head and the adjustable dial was easy to work with. I will warn though if you wear extensions or have an xlarge head this may not fit.

Pretty sure it saved my life
I weight about 225 lbs, my ebike weighs about 110lbs. So 335 lbs combined. That's a lot of inertia.I was cruising at about 25 mph when I lost traction and slammed front wheel first into a large boulder off to the side of the trail I was on.I of course went over the handlebars and my head smacked the boulder, helmet first and I heard a crunch.Have you ever had time slow down when something awful was happening when you have an unreasonable amount of thoughts take place in a very short period of time? From the time of the crunch to the moment I hit the ground, I was so thankful I was wearing a helmet and I from the sound of it, I was POSITIVE the helmet was done for.After laying on the ground for a few minutes determining if I was bleeding profusely / if anything was broken, I got up, popped the helmet off to take a look at it and it looks as it does in my picture. Hardly any damage! And my head is 100% fine. I don't even know that I got a bruise out of it.I'm quite confident this helmet saved my life.That being said, the padding seems to be great, it's not uncomforable to wear at all. I often forget I'm wearing it. It offers great cooling. My head actually feels cooler when wearing the helmet and riding than without the helmet.The size fit really well and offers a wide amount of adjustment to get a good fit.Any helmet that prevents bad injury is worth whatever the cost but the cost of this product is especially a great value compared to other larger name, comparable helmets in the segment.

Very comfortable
I have never liked wearing a helmet for biking but realize that safety comes first so I bought this helmet. It’s so comfortable I forget I’m wearing it. I also love the light blue colour.

Léger et confortable
Le look old school j'adore. En plus il est léger, confortable, procède un ajusteur dernière la tête et 3 différentes fonctions de lumière. Pour le prix c'est parfait.Je ne donne pas 5 étoiles parce qu'il y a une très légère bosse sur le dessus du casque (sur le plastique). J'ai essayé d'enlever la lumière dernière le casque mais après une dizaine de tentatives j'ai arrêté pour éviter d'endommager le casque (il n'y a pas de vis pour cette lumière).
