Giro Scamp II Youth Bike Helmet Review: Features and Performance

Updated November 2026

The giro scamp ii youth bike helmet is a lightweight, well-ventilated option for kids who ride bikes, scooters and balance bikes on paved paths, neighborhood streets and easy trails. It is best suited to parents who want a helmet that feels comfortable enough for a child to actually wear on every ride, and who plan to fit it carefully. It is less suited to kids who ride aggressive downhill terrain or who need a full-face or MIPS-equipped helmet as a requirement. Parents shopping for a more protective variant should also look at the MIPS version of this line.

Product Overview

The Giro Scamp II Youth Bike Helmet in Matte Blue Jewel, size Small, is a youth-sized, in-mold style helmet from a brand that has produced cycling helmets for decades. The product listing describes it as a lightweight Scamp II helmet that delivers cooling comfort and an easy fit. Those are the two claims most parents will care about: a helmet a child will not resent wearing, and one that stays adjusted without constant fiddling.

The Scamp II sits in Giro’s youth lineup as a non-MIPS model. That distinction matters. The MIPS version adds a low-friction liner intended to reduce rotational forces in certain impacts, while this version relies on standard in-mold construction. Both are designed for recreational riding, but they are not interchangeable in terms of features. If you are weighing the two, the sibling model is covered in our article on the Giro Fixture MIPS II Bike Helmet, which explains how MIPS-style liners work in adult helmets and what that means for a rider’s choice.

Because this is a youth size, the sizing system is built around children’s head circumferences rather than adult ranges. Small is the size most often associated with younger riders, and the listing specifies this size explicitly, so buyers should measure their child’s head before ordering rather than guessing by age alone.

Key Features & Specifications

The table below lists only the details that are stated in the product name or are consistent with how this model is generally described. Where a specification is not confirmed in the listing, it is omitted rather than estimated.

Feature	Details
Product type	Youth bike helmet (recreational riding)
Brand / model	Giro Scamp II
Color	Matte Blue Jewel
Size	Small (youth)
Weight positioning	Marketed as lightweight
Comfort claim	Cooling comfort
Fit claim	Easy fit
MIPS	Not included in this model (MIPS version is a separate listing)
Helmet style	Standard youth shell, not full-face

Before buying, confirm the helmet carries the safety certification required in your region. In the United States, bicycle helmets are expected to meet the CPSC standard for bicycle helmets (16 CFR 1203), and reputable youth models carry a permanent label stating compliance. Check the label inside the shell rather than relying only on the listing text.

Pros & Cons

Pros

• Marketed as lightweight, which many younger riders find easier to tolerate on longer rides.
• Cooling comfort is a stated design focus, helpful for kids who overheat in warm weather.
• Easy fit is a listed feature, and youth helmets with simple dial or strap systems are generally quicker to adjust for a child’s head shape.
• Available in a Small youth size that targets smaller head circumferences.
• Matte finish and blue colorway are often preferred by kids who want a helmet they will wear without argument.

Cons

• No MIPS liner is included in this version, so parents who want that feature will need the sibling model.
• Not a full-face design, so it offers no chin protection and is not intended for aggressive off-road or jump riding.
• Sizing is limited to the Small youth size in this listing, which may not suit every child in the same age bracket.
• Fit and comfort depend heavily on proper adjustment, and a poorly fitted helmet will underperform regardless of its design.

Performance Analysis

Performance for a youth bike helmet comes down to three things: how well it protects in a crash, how well it stays on the head, and whether the child will keep wearing it. The listing does not publish impact test data for this model, so any analysis here is based on the product’s stated design goals and on common patterns that owners and parents tend to discuss.

On protection, the core job of any certified helmet is to absorb energy through an expanded polystyrene liner and spread impact over a larger area. A non-MIPS helmet like this one depends entirely on that liner and the shell. The absence of a rotational-force liner is the most significant difference from the MIPS variant. For low-speed falls on pavement, which make up most childhood bike accidents, a certified in-mold helmet is designed to meet the required standard. For higher-speed or more complex impacts, a MIPS model offers an additional layer of design intent that this version does not.

On comfort and cooling, the stated focus is on airflow. Lightweight helmets with multiple vents tend to feel cooler, and owners of youth helmets frequently mention that a lighter shell reduces neck fatigue on longer rides. Many parents report that comfort is the factor that determines whether a child wears the helmet at all, so this emphasis is practical rather than cosmetic.

On fit, owners of youth helmets commonly report that the adjustment system and strap positioning determine whether the helmet stays level. The rule to follow is simple: the helmet should sit two finger-widths above the eyebrows, the side straps should form a V under each ear, and the chin strap should allow one or two fingers between the strap and the chin. A helmet that rocks side to side or tilts back exposes the forehead and should be readjusted or resized before the next ride.

Overall, the Scamp II appears to be a reasonable choice for recreational youth riding when it is properly fitted and checked for certification. Its strengths are comfort and ease of use, while its limits are the lack of MIPS and its non-full-face design.

Who Should Buy This Product?

This helmet suits parents of children who ride bikes, balance bikes or scooters on paved paths, neighborhood roads, bike parks with easy terrain, and casual trails. It is a sensible choice for a child who needs a comfortable, light helmet for everyday riding and who is not attempting jumps, drops or steep technical descents. Parents who want a helmet their child will wear without constant reminders will also find the lightweight, cooling design worth considering.

Parents who should skip this model include those whose children ride downhill, dirt jumps or motocross-style terrain, where a full-face youth helmet is the more appropriate category. Families who want MIPS as a standard requirement should choose the MIPS variant instead. If your child has a head shape that does not sit well in a standard youth fit, consider trying the helmet in a store before purchasing, or consult a helmet fitter for guidance.

Buying Guide

Choosing a youth helmet is less about the brand name and more about getting the right size, the right certification and the right coverage for how your child rides. Use the steps below before you order.

1. Measure the head. Wrap a soft tape measure around the head about one inch above the eyebrows and above the ears. Compare the number to the manufacturer’s size chart, not to the child’s age.
2. Confirm the certification. Look for the CPSC label inside the helmet. Helmets without a visible certification label should be avoided.
3. Decide on MIPS. If your child rides on varied terrain or wants the additional rotational-force design, choose a MIPS model. If you want a lighter, simpler helmet for paved and easy riding, a non-MIPS helmet may suit.
4. Match the coverage to the riding. Standard youth helmets cover the top and back of the head. Full-face helmets add chin protection and are the right category for aggressive riding.
5. Test the fit. Adjust the retention system, buckle the chin strap, and shake the head. The helmet should not move independently of the skull.

Several well-known alternatives are worth comparing if you are still deciding. The MIPS version of this same line adds rotational-force protection and is the most direct upgrade, and you can see its details here:

FAQ

Is the Giro Scamp II a certified youth bike helmet?

Youth bike helmets sold in the United States are expected to meet the CPSC bicycle helmet standard. Check the certification label inside the helmet before purchasing, since listing text alone is not enough to confirm compliance.

What size should I buy for my child?

Measure your child’s head circumference about one inch above the eyebrows and compare it to the manufacturer’s size chart. Do not rely on age alone, because head size varies widely between children of the same age.

Does the Scamp II have MIPS?

This model is the non-MIPS version. The MIPS variant is a separate product in the same line and includes a rotational-force liner.

Is this helmet suitable for mountain biking?

It is designed for recreational riding. For aggressive trail riding, downhill or jumps, a full-face youth helmet is the more appropriate category.

How do I know if the helmet fits correctly?

The helmet should sit level, about two finger-widths above the eyebrows. The side straps should form a V under the ears, and the chin strap should allow one or two fingers between the strap and the chin. The helmet should not shift when your child shakes their head.

How long does a bike helmet last?

Manufacturers generally recommend replacing a helmet after a crash, after visible damage, or after a set number of years of use as stated in the owner’s manual. Heat, sunlight and sweat can degrade materials over time, so inspect the helmet regularly. For specific guidance, consult the manufacturer or a qualified bike shop.

Can I use a sticker or accessory on the helmet?

Stickers can be applied but should not cover vents, straps or the certification label. Check the manufacturer’s guidance on adhesives and avoid anything that could affect the shell or liner.

Should I buy a MIPS helmet instead?

If your child rides on varied terrain or you want the additional rotational-force design, a MIPS model is worth the consideration. For easy, paved and neighborhood riding, a non-MIPS helmet with a good fit and proper certification remains a sensible choice.

Final Verdict

The Giro Scamp II Youth Bike Helmet in Matte Blue Jewel, Small, is a lightweight, comfort-focused helmet for children doing recreational riding. Its stated strengths are cooling comfort and an easy fit, and those qualities matter most for kids who need to wear their helmet consistently. It is not a full-face helmet, and it does not include MIPS, so it fits best for paved, neighborhood and easy trail riding.

If your child is a casual rider who values comfort and simplicity, this helmet is worth considering after you confirm the size and certification. If your child rides more aggressively or you want rotational-force protection, look at the MIPS version or a full-face youth model instead. As always, a helmet only protects when it fits properly, so measure carefully and check the fit before every ride. For personal guidance on fitting or safety, consult a qualified bike shop or helmet fitter. View on Amazon
