I chose this because of the magenta/purple color and love it. While it's marketed as a youth helmet, it can fit a woman's head. I 'm a 5' 4 '' adult woman, and my head size is 55- 56, so within the 50- 57 size. I tend to have a `` hot head, '' but the ventilation on this helmet is excellent, so my hair was n't wet after a 1- hour bike ride. It fits well, is super lightweight and comfortable, and the Roc- Loc fit system allows a perfect fit. My only scare was the Roc- Loc was fully tightened when shipped, so when I first tried it on I thought it was too small. Once we loosened it, it fit well, and then even better once tightened.

My wife and I enjoy biking both solo and together. We usually go slow and enjoy the scenery. Two summers ago my wife said her sister who is a physical therapist started wearing a helmet after working with patients who had been injured in accidents and my wife started considering a helmet. A few months ago my wife bought a retrospect rowan helmet She wears it on almost every ride. A few days ago i took a ride and she offered it to me to try and i must say i do feel Safer with it on.

I did n't have much expectation wise when buying a helmet online but honestly I could n't be happier with this purchase. This helmet is more comfortable than a bike helmet has a right to be. Very breathable and the color and look is just the icing on the cake. Love this helmet and will be buying upgrades for the rest of the family.

[ 2nd time buying. Great helmet. Low profile so doesn ’ t look like you have a garbage can on your head. Very comfortable. Only issue I took the inner liner out to wash and broke the mips plastic holding tabs. They don ’ t service them so I had to buy a new helmet. Keeping my old one for spare tabs in case it happens again. Also huge plus they sell replacement liners so you don ’ t have to throw it out when it gets nasty from sweat. Overall favorite helmet I ’ ve owned so far

My husband and I did not wear helmets. As my husband started riding more mountain and off road i purchased him a bell 4forty for his off road adventures. He generally only wears it in the woods and even then not all the time( which is fine by me). He says it fits nice and is comfortable and feels very substantial and he is often glad he has it. A few weeks ago I decided to go on a leisurely ride solo. As I was loading my bike I decided to borrow my husbands helmet for the ride since i was headed into town. I tried it on and got it adjusted it was very easy to adjust and comfortable although heavier than my ball cap. During the ride It was so snug and airy i kept forgetting it was on. I did feel Safe And rode more naturally. I always assumed helmets were clumsy and bulky and poor fitting. However I am now considering my own helmet as a little extra protection could never hurt

This is my fourth Forefront helmet. They fit perfectly never get too hot and are light and durable. The only parts that are subject to wear and tear are the pads. They do a great job of resisting sweat but eventually after drenching them a few hundred times they succumb.( I am amazed at how long they last given what ’s tossed at them, but wish I could buy replacements.

[ I went from a more expensive helmet that needed to be replaced, due to age, to this helmet and glad that I did. It feels like a more expensive helmet. Size chart was accurate, it sits well on my head, and stays put while riding. The visor position is fixed but is exactly where I need it to be. Will but again when the time comes.

[ Feel like the title says it all. Been wearing a POC helmet for mountain biking for a few years now and have been completely satisfied with it, so when the time came to get a new road helmet, it was a no- brainer to stick with POC again. Wanted a low profile helmet, with good coverage and lots of ventilation. This helmet checks all the boxes. Could have gone up or down on sizing, but ultimately sized up to give me the flexibility of fitting a cap or thin beanie underneath. Helmet sizing has been easy to adjust and stays put. Totally satisfied.

This helmet looks sick and fits like a dream. The new MIPS Air Node system is very neat, hopefully I don ’ t test that out any time soon, and the Boa system for adjusting fit works very smoothly, and drops back into the helmet for transport and placing on tables. Over all this matches the Smith gold standard to a T.

The color is not as orange as the picture, it looks coral in person which I liked better. The sizing was good. I ’ m not sure what the other person is talking about in the other review. I apparently have a big head( the giro women ’s universal helmet didn ’ t eve fit on my head). I tried on a medium of this helmet in the store and it was perfect, a tiny bit of space and used the adjustable knob to make it tighter. It ’s very lightweight and looks pretty good for a helmet. Very low profile but with full coverage on my head that feels safe for my e- bike. It also has MIPS protection. It also has a lot of holes so seems very breathable.

Justin P.
This is easily the most comfortable full face I 've ever used. The pads included allow you to really dial in the fit. The lack of the front mesh piece makes it easy to get a bit valve or squirt from a bottle. There is some noticeable MIPS rattle, but with everything else going on around me when I 'm riding downhill, it's of no concern.

Love this helmet. Fits great, light weight, plenty of ventilation
When selecting a lightweight mountain bike helmet, consider features such as ventilation, fit, and safety certifications. A well-ventilated helmet will keep you cool during rides, while a secure fit ensures comfort and stability. Additionally, look for helmets that incorporate advanced safety technologies to protect against impacts.
The weight of a mountain bike helmet can significantly impact your performance, especially during long rides or climbs. Lighter helmets reduce fatigue and allow for better maneuverability, making them ideal for mountain biking. However, it's essential to balance weight with safety features to ensure adequate protection.
Lightweight mountain bike helmets are typically made from materials such as expanded polystyrene (EPS) foam for impact absorption and polycarbonate or in-molded shells for durability. These materials help keep the helmet lightweight while maintaining safety standards. Some helmets may also feature moisture-wicking liners for added comfort.
While lightweight mountain bike helmets are designed for performance and comfort, their suitability can depend on the type of riding you plan to do. They are great for cross-country and trail riding, where weight and ventilation are crucial. However, for more extreme downhill or enduro riding, you may want to consider helmets with additional coverage and protection.
To ensure a proper fit for a lightweight mountain bike helmet, measure your head circumference and refer to the manufacturer's sizing chart. The helmet should sit level on your head, with the front edge just above your eyebrows. Adjust the straps and retention system for a snug fit without causing discomfort, ensuring it stays in place during rides.
