What experts liked

This helmet features a simple design and an easy fit for the rider who prefers the safety and protection of a classic bike helmet without the added bulk or compromised performance. Molded construction helps to minimize the overall weight while an easy one-handed dial adjustment system makes it simple to find the ideal size and fit. The head will stay cool even in warmer weather thanks to a total of 22 vents.
- Heavy
There is ample padding on the inside that is pretty comfortable. The internal shape of the helmet is good too and felt comfortable on my head. This helmet is consistent with other Giro helmets, which seem to suit a wide range of different peoples heads. The padding is also removable, meaning you can wash it if it starts to get smelly and sweaty after several rides – a feature you don't always see on entry level helmets at this price point.
- Cycling Weekly
Fit for me was comfortable and a lot better than cheaper helmets that I have worn in the past. In fact, there wasn't a lot to distinguish it from helmets four times the price in this aspect. The fit is helped by borrowing from the premium helmets the Acu Dial system, a single dial you can adjust with one hand for tension around the head. It allows a fine step adjustment to minimise pressure points, and if it does feel too tight, that can be easily remedied on the bike.
- Road.cc
This Adult helmet comes in 1 size(s) and rated Excellent in our impact testing. With the number (3) and type of features for adjusting the retention strap, it provides a(n) good ability to customize the fit. And with an approximate weight of 281 grams, the weight of this helmet is considered best relative to other helmets tested.
- Consumer Reports
This helmet does what is says it is a utilitarian helmet and adjustable while fitting comfortable on your head. It provides you with protection when needed the most. It keeps my head cool, especially on hot days as the extra holes on the back keeps your whole head cool and great for me.

What experts didn't like

Runs a bit small. Strap design could be better. Could use more side padding.
- Heavy
Slightly heavy. Retention system is little bulky. The chin strap is different from the standard clip on other helmets. This slide through design is bulkier and heavier.
- Cycling Weekly
The vents are smaller and with greater spacing than you'll find on a performance helmet. The weight is more noticeable as you move your head about.
- Road.cc
It scratches easy when riding through the woods. It does not have that much padding.

An Overview On Bike Helmets For Women

Wearing a bike helmet is an excellent way to ensure you stay safe on your adventure. While all bike helmets for women in the U.S. need to meet the same high standards for impact protection, there is still a lot of variety between brands and styles.

When you’re selecting a bike helmet for women, the most important thing to consider is how it fits. A bike helmet for women that does not fit properly may not protect you properly during a crash. Be sure to find a helmet for women that fits snugly and is easily adjustable. Measure the circumference of your head to see which size you need for your helmet. When you’re wearing your helmet for women, be sure to adjust the tightness. You may need to open the adjustment wheel fully when you place the helmet on your head, and then tighten it to fit you.

The chin strap also needs to fit snugly, but not too tightly. You should be able to comfortably open your mouth wide with the chin strap buckled. If it feels too tight, you will need to loosen the strap slightly. Keep in mind that brand sizing for helmets for women vary, so always measure your head circumference first. If you find that you’re between sizes, then opt for the smaller size, which will give you a better fit.

In addition to how the helmet for women fits, you’ll want to consider the features the helmet provides. Ventilation is important for some riders because it helps keep you cooler and more comfortable. The number of vents also affects how heavy the helmet for women will be. Some riders prefer to have a visor on their helmet, helping to keep the sun out of their eyes. If you like to film your adventures, you may want a bike helmet that has mount compatibility for a light or a camera.

The Bike Helmet For Women Buying Guide

  • The fit is the primary factor to consider when selecting your bike helmet. The fit affects not only the level of comfort but the level of safety your helmet provides. Be sure to measure your head circumference when selecting your helmet size, and keep in mind that different brands may have a variance in sizes. Be sure to check for several adjustability features so you can customize the fit of your helmet for your head.
  • The sole purpose of a bike helmet is to protect your head from impact if you fall off your bike. Because of this, it’s important to consider the kind of safety features your helmet has and whether they meet the needs of the kind of rider you are. Most helmets have two separate parts, the plastic shell and the interior liner. The goal of the plastic shell is to provide puncture resistance and protect your head by sliding on impact. The liner’s role is to slow down the movement of your head and dissipate the force of the impact.
  • Riding your bike will cause you to sweat, so many riders prefer to have a bike helmet for women with a well-constructed ventilation system. You don’t want to be dripping with sweat during your ride, then ventilation in your helmet can help to keep you cool and comfortable.
  • Whether you’re riding your bike around town or taking it off-roading, you may want to consider anti-theft features of your helmet for women. While it’s convenient in some situations to take your helmet with you after you have locked your bike, you may also want the option to leave your helmet with your bike — and know that it’s going to be there when you get back.
