Giro Dime MIPS Kids' Cycling Helmet

Full Review of the Giro Dime Kids’ Helmet

This is one of those helmets that will always be a favorite for your cycling kid(s). It will inspire safety in them because they will always want to wear the skater-style and rad-looking cycling helmet, the Giro Dime.

The Giro Dime comes with enough vents to allow the free flow of air into your kids’ hair when they ride, effecting the cooling effect, which is needed, especially during hot weather or when the kids sweat via their heads, which is expected during intense cycling sessions.

It is a comfortable, lightweight, high-quality, and stylish kids’ helmet. It has sealed pads, with the thick rear pad and the front pad only in the middle to allow maximum airflow.

Let’s dig deeper into what the Giro Dime offers for a parent looking for a good helmet for a kid who cycles.


One of the best features of any helmet is the adjustability that provides a good fit for the rider. A helmet that doesn't fit properly puts the child's head and brain at risk. Giro Dime has a good adjustability and super-sized system, which they base on their over 25 years of handcrafting skills and human scale factors.

The super-sizes fit riders comfortably like they are custom-made. The long straps and ears strap holders must be adjusted to fit the rider.

 The helmet also has a Fit Kit pad system which includes two sets of pads for each side and one for the front that goes on top of the existing pads. These pads are designed to offer a comfortable fit and prevent sweat from running down the rider's face, which could be distracting.

These pads have varied thicknesses; The one at the back is thick while that in the front comes in two thicknesses, and the middle is slightly thicker to allow a good flow of air.

The pads are swappable, so you can remove them if they are sweaty. You can also swap them when the rider grows to achieve a proper fitting.


Don't make the mistake of using the child's age as a basis for choosing a helmet. This is because most children have different head proportions, and kids of the same age may wear different-sized helmets. Check out our kids' helmet fitting guide for appropriate fitting and sizing of a kids’ helmet.

Since the helmet comes in two sizes, extra-small (47-51cm) and small (51-55cm), you have to measure the circumference of your child's head to get their proper size fitting.

If unsure how to do this, take a measuring tape, start in front of the child's center of the forehead just slightly above the eyebrows, and wrap it around the head right to where you started. Then use those measurements to purchase the correct helmet. Alternatively, you can ask the retailer for help. 

You have to get this right since the helmet lacks the dial-adjust system.

One of our testers, a four-year-old with a 51.4 cm head circumference, tried a small size, which was extremely large for them, even with the added pads. But after trying the extra small, his head fit perfectly, and they loved it.

We decided to get our second tester, a two-and-a-half-year-old, the extra small since he has a head circumference of 50 cm. He loved it, but it was a bit loose, and the straps were long, so it's unlikely they will get tight enough. There is about a 10" extra loop that we folded and tied to the opposite side ear to prevent it from dangling down his chest, as this could be a bit distracting.


The aim of wearing a helmet is to be safe, and you have to trust that what you are wearing is guaranteed to offer that. Giro Dime is certified by the US CPSC Safety Standard for helmets for people aged one and older, which means it has undergone proper tests to ascertain the fact.

Giro helmet is also fitted with the rotational mitigation technology known as MIPS. It is a thin web of high-quality plastic that flexes upon impact, reducing the rotational force that could easily be transferred to the rider preventing concussions. Giro makes helmets with MIPS and without. Therefore, it is worth noting that it can feel a bit heavy compared to one without.

The helmet's outer shell is made of ‎high-quality Acrylonitrile Butadiene Styrene (ABS) material which offers superb impact resistance. The inside of the shell is made of Polyurethane bumper coating, a high-quality and durable material that protects the exposed EPS liner from wear and tear, which increases its durability, making the helmet an excellent investment for your kids.

Design and Color

When buying a helmet for your young one you want them to wear, you have to consider that children are picky and stubborn, especially when gifting them. Let them choose the color and design they like to save you the headache. Though it doesn’t feature 3D designs like Raskullz helmets, it comes in various attractive colors like matte blue, black, Orange, and purple, which all kids will love.

Now that we've looked at what makes it tick let's quickly look at the pros and cons.

  • It comes in two models, one is equipped with MIPS technology, and the other isn’t
  • It provides good airflow
  • It comes in two sizes, small and extra-small
  • It is unisex
  • It doesn’t have a dial adjust system

Bottom Line

A helmet is essential when you are trying to introduce your young one to bikes, skates, or scooters. If you are looking for a helmet that a child can use for the neighborhood, street, or trail rides, consider Giro Dime; you and your kid(s) will love it.

The Dime is not just a kid-sized helmet; it's a miniature version of its adult counterpart. The concept is to take a full-grown adult bike helmet and shrink it to a smaller size with almost all the features, and the result is the fantastic Giro Dime helmet, which is perfect for kids and youths. It is solidly made with fun colors and won’t cost you much. It eventually takes the space of the best skater-style helmet for kids who cycle, as it is not dual-certified.

It is also available in two models, one with MIPS and one without, both perfect choices. The Giro Dime also comes with a one-year warranty from the manufacturer, beginning from the purchase date.

So, if you run into any problems, you can return it for repair or replacement. The Dime checks many boxes but doesn't have a dial adjust system.
