Full Review

Giro’s Tremor and the Hale recently made a quiet entrance into the kid’s helmet market, but we want to shout from the rooftops how much we love both of them!  The Tremor is similar to the very popular Bell Sidetrack, except that for just $5 more, it’s a much better helmet. The Hale is an update on Giro’s own Raze helmet, and they fixed everything about the Raze that we thought was a bit annoying. Two big thumbs up to Giro for taking kids’ helmets to the next level! Both models are available in optional MIPS safety technology, so can we give them four thumbs up?? Both the Tremor and Hale are exceptional helmets, and for most kids, it just comes down to style or color preference.

Coverage and Size

Coverage

Because the Tremor is stylized like a mountain bike helmet while the Hale is a junior cycling helmet, the Tremor has more coverage in the back and sides, but both helmets provide plenty of coverage to keep your child’s head safe in the event of a crash. 

Size

The Tremor and the Hale are standard “Youth” sized helmets fitting kids’ heads in the 50 – 57 cm circumference range. At their widest point, they’re 16.5 cm, just slightly smaller than the Sidetrack at 17 cm. It’s incredibly important to remember that heads come in many different shapes. You could have two kids with a head circumference of 55 cm, but they many not be able to fit in the same helmet depending on how wide or tall their head is.

While the Bell Sidetrack‘s sides narrow when the dial adjust knob is turned to make the helmet smaller, the sides are fixed on the Tremor and the Hale. So if your child’s head is a little wider than average, the Giro helmets would probably be the better choice. If your child has a very wide head, skater-style helmets like the Melon, are usually the route to go.

Adjustability 

Giro’s Roc Loc adjustment system is A++ and is definitely a step up from the Sidetrack and most other helmets we’ve seen.

Dial Adjust

The dial adjust system of both the Tremor and Hale feature a slightly larger dial that’s covered in a rubber grip to make it so much easier to adjust, especially when it’s already on a child’s head. The Sidetrack dial is harder to grip and also doesn’t dial-in nearly as smoothly.

Dial Adjust and Pads on Tremor & Hale vs. Bell Sidetrack

Dial adjust on Giro models have larger, rubber dial, while Bell Sidetrack's is cheaper plastic. Pads for Giro Tremor are high-quality with air channels, while Giro Hale and Bell Sidetrack do not have air channels.

Pads

While many higher-end helmets come with multiple sets of pads of different thicknesses to better customize the fit for your child, it seems to be a trend to forgo the extra set of pads. This keeps costs down, and also gives parents one less thing to worry about when adjusting the size of their child’s helmet. And while it may be nice to have a set of thinner pads to exchange out as your child grows, if you can manage to keep track of them that long, you’re far better parents than we are. 🙂

The Tremor and Hale are both lined with high-end sealed pads to prevent sweat from dripping down your child’s face, but also, the side that touches the skin is a high-end athletic performance material called Quick-Dry padding. These pads are definitely among the nicest we’ve seen and are an upgrade from the pads of the Bell Sidetrack and the Giro Raze, which are sealed but don’t feature the technical fabric.

There is a slight difference between the pads on the Tremor and Hale. The cushioning of the Tremor’s pads are broken up periodically with small air channels to promote better air flow and ventilation, while the Hale’s is not.

Side Straps

Correctly adjusting the sliders on a helmet’s side straps is one of my least favorite things to do in life. It is SUCH A PAIN but completely necessary to have a truly great and lasting fit. THANK YOU, Giro for removing this first world problem from my life.

The Tremor and Hale both feature side straps that are fixed, don’t need to be adjusted and aren’t part of their fit system. (Most kids’ helmets require adjusting the side straps to get a proper fit.) We love it! We also love that the side traps are a much softer and more tightly woven fabric than the traditional nylon found on the Sidetrack and most other helmets. They feel soft against the skin and look pretty sweet.

Side Straps and Buckle on Tremor and Hale vs. Bell Sidetrack Side straps of Giro models do not have side strap adjusters and are higher quality material than the standard on Bell Sidetrack. The buckle on the Giro models is standards while the Sidetrack features PinchGuard.

Buckle

The buckle on both the Tremor and Hale is a standard-style buckle. While more expensive helmets are starting to upgrade to magnetic, pinch-free buckles, we don’t mind a traditional buckle if it helps keep costs down. We also love this buckle because, while basic, it’s easy to use. The Sidetrack and many other child helmets feature a buckle called the “Pinchguard” that supposedly prevents your child from getting pinched while buckling or unbuckling. Sometimes it works, sometimes it doesn’t, but it’s also really hard to use and just kind of annoying.

The excess buckle strap on the Tremor and Hale is spot on – just enough for what you need without all the excess strap found on other helmets.

 

Construction, Vents, & Visor

This area is where the Tremor and the Hale differ the most.

Weight

With more coverage and less venting, the Tremor weighs 306 g while the Hale is one of the lightest weight helmets we’ve seen, at 247 g. The Tremor, however, does way about 14 g less than the similar Bell Sidetrack.

Construction

The Tremor and Hale feature in-mold construction which means that the outer shell is fused with the inner foam core so the helmet is one solid piece. This is the preferred type of helmet construction because it keeps quality high and the weight low. The Raze does have slightly more coverage over its foam core than the Tremor. Exposed foam can get damaged more easily, so while still providing adequate protection, helmets that have more of the foam covered do have a bit more durability. This is the one area where the Sidetrack actually beats the Tremor. That said, the Tremor’s coverage is absolutely sufficient and worthy of a high-end helmet.

Slight Differences in Tremor, Hale, and Sidetrack Outershell CoverageIn-mold construction covers more foam on the Hale than the Tremor but Sidetrack has best coverage of all.

Visor

The visor on the Tremor extends out farther than most visors we’ve seen, including the Sidetrack, providing more protection from the sun. The visor on the Hale is much smaller, but is also consistent with other cycling helmets.

The visor on the Tremor is longer than the Hale's.

 

Venting

Continuing the legacy of the Raze as a helmet with superior ventilation, the Hale still features 22 vents and 5 air channels running from front to back. If you live in a hot climate, the Raze should be high on your list of helmets to consider.

The Tremor also features 5 air channels, but only 18 vents. This is better, however, than the Sidetrack with just 15 vents.

MIPS

For an additional $20, the Tremor and the Hale both offer versions available with MIPS (Multi-directional Impact Protection System). MIPS is the latest and greatest in helmet technology and is a feature we highly recommend. Helmets are not fashion accessories, but safety accessories. Anything that can make a helmet more safe for your child is something you should consider.

The foam core of a helmet protects a child from direct impact but does not protect the head and neck from twisting during an impact.  MIPS (Multi-directional Impact Protection System) allows the energy from the crash impact to be absorbed by the helmet regardless of what direction the impact is coming from. The MIPS system works by allowing the helmet to slightly rotate around the head during a crash. The rotation is possible due to rubber anchors that adhere an inner plastic MIPS shell to the outer foam shell of the helmet.  In an impact, the anchors stretch to allow the outer foam shell to rotate around the innder plastic MIPS shell.

While in earlier versions of MIPS helmets the MIPS anchors would snag on long hair, the Tremor and Hale’s internal pad system covers the MIPS anchors so this is a non-issue.

Giro’s New MIPS Upgrades vs. Bell Sidetrack

Inner MIPS layer on the Giro Tremor vs. the Bell Sidetrack. The Tremor has much less plastic, allowing for better ventilation.

What we’re most excited about with the MIPS system we’re seeing in these new helmets is that they’re actually incorporated into the dial-adjust cage and are slimmer in design. What this means is less plastic making your child’s head sweat! Besides long hair catching on MIPS anchors, sweaty-head-syndrome has been the other small issue with MIPS. While we strongly believe that the added safety MIPS provides has been worth these minor inconveniences, it looks like Giro and MIPS are making great strides in comfort. The Sidetrack’s pads do cover the MIPS anchors, but that helmet does not feature the upgraded MIPS cage design.

While we still think the Bell Sidetrack is a great helmet, the truth is, the new Giro Tremor is just better.

The Raze was a great helmet, but Giro’s upgrades with the Hale really do make a big difference!

Bottom Line

The Tremor and the Hale are both phenomenal options for your child’s next helmet. With one of the highest quality and easiest to use adjustment systems available in a kid’s helmet, great ventilation, durable and lightweight construction, and optional MIPS models, Giro has hit a home run with these helmets.  When choosing between the Tremor and Hale, it might just come down to which colors and designs your kid likes better!
