Giro Scamp MIPS II Youth Bike Helmet Review: Is It Worth It?

Updated November 2026

The giro scamp mips ii youth bike helmet is aimed at young riders who need MIPS-equipped protection in a small, lightweight shell with a fit system that can grow with them. It suits parents buying for kids who ride on paved paths, neighborhood streets, pump tracks or light trails, especially children whose heads fall within the Small sizing range. It is a weaker choice for families who want a full-face helmet for aggressive downhill or jump riding, for children with heads that measure outside the listed size, or for buyers who need a helmet with a visor or chin bar. Before buying any youth helmet, measure your child’s head circumference and check the manufacturer’s size chart. If your child has a medical condition affecting balance or head protection, or you are unsure which category of helmet fits their riding, ask a pediatrician or a qualified bike fitter for guidance.

Product Overview

The Giro Scamp MIPS II is a youth open-face bike helmet in a Matte Pink/Green colorway, listed in the Small size. Its listing describes it as small but feature-packed, combining modern protection with airy comfort. Giro positions the Scamp line as a kid-focused option within its broader helmet range, and the MIPS version adds a low-friction liner intended to reduce rotational forces in certain angled impacts. The helmet is designed for general cycling use: riding to school, around the neighborhood, on bike paths and on casual trails. It is not designed as a full-face or downhill-specific helmet.

Giro has built a reputation across road, mountain and youth categories, and the Scamp name has been used for several generations of kids’ helmets. The MIPS II version is the update that adds the rotational impact system to the lightweight youth shell. Owners tend to discuss it in terms of how easy it is to adjust, how light it feels on a child’s head, and how well the ventilation keeps things cool during warm-weather rides. Because product details can change between model years, check the current packaging and manufacturer documentation before you buy.

Pros & Cons

Pros

• Includes MIPS rotational impact protection, which is uncommon in lower-priced youth helmets.
• Lightweight shell that most children find comfortable for longer rides.
• Vent layout is designed for warm-weather riding, and owners often mention it stays cooler than heavier kid helmets.
• Dial-style fit adjustment makes it easier to get a snug fit without straps that rub or slip.
• Matte colorway and a kid-friendly look that many children want to wear.
• Comes from an established helmet brand with a long history in youth cycling.

Cons

• Open-face design offers no chin or face coverage, so it is not suitable for jumps, drops or downhill runs.
• Only one size is shown in this listing, so children at the edges of the Small range may need a different size.
• Fit depends heavily on correct measurement; a helmet that is too large can shift during a crash.
• The lightweight shell may feel less substantial to parents who are used to heavier kid helmets.
• Some colorways and sizes sell out quickly, so availability can be inconsistent.

Performance Analysis

Performance for a helmet like this comes down to three things: how well it protects, how well it fits, and how comfortable it is over time. On protection, the MIPS liner is the headline feature. MIPS systems are designed to allow a thin low-friction layer to move slightly relative to the head during oblique impacts, which can reduce rotational forces that are associated with certain brain injuries. The benefit is real but should be understood as an added layer of protection, not a guarantee against injury. Helmets of any type only work as intended when they are the right size, correctly positioned and not damaged.

On fit, the Scamp MIPS II relies on the adjustment system to secure the helmet. Owners generally report that the dial makes fine adjustments easy, which matters because children grow and change shape over the course of a season. The helmet should sit level on the forehead, about two finger-widths above the eyebrows, with the side straps forming a V under each ear. The chin strap should allow one or two fingers to slide under it when fastened. If the helmet rocks forward, back or side to side when your child shakes their head, it is too loose.

On comfort and ventilation, the lightweight shell and multiple vents are the main draw. Owner feedback commonly mentions that the helmet feels airy during warm rides, which helps children stay focused and less irritable on longer outings. Heat and sweat can still build up on very hot days, so a quick check of the padding after rides is a good habit. Replace the helmet after any significant crash, and follow the manufacturer’s guidance on replacement intervals, which is typically several years from the manufacture date regardless of visible condition.

Who Should Buy This Product?

This helmet fits best for children who ride casually and need a MIPS-equipped, lightweight option. Good candidates include kids riding to school, learning to ride on bike paths, joining family rides on paved trails, or starting to explore gentle dirt and gravel routes with supervision. Parents who want a helmet their child will actually wear, rather than one that feels heavy or hot, will likely appreciate the design.

You should skip this helmet if your child rides BMX, jumps, practices downhill or rides aggressive trails where face protection is important. In those cases, a full-face youth helmet is a more appropriate choice. Parents of children whose head measurements fall outside the Small range should also look elsewhere, and anyone who needs a helmet with a visor or extended coverage should consider other models.

Buying Guide

Before you buy any youth helmet, follow these steps:

1. Measure head circumference about one inch above the eyebrows, around the widest part of the head, using a soft tape measure.
2. Compare that number to the manufacturer’s size chart, not to a generic age range. Kids of the same age can have very different head sizes.
3. Choose the size that matches the measurement, then check fit with the helmet on: it should be level, snug and not shift when the head moves.
4. Confirm the CPSC certification label is inside the helmet, which indicates it meets US safety requirements for bicycle helmets.
5. Plan to replace the helmet after any crash, even if no damage is visible, and check the age guidance from the manufacturer.

If you are comparing options, two well-known alternatives are worth considering. The first is the Giro Scamp II Youth Bike Helmet, which uses the same general Scamp design in a lightweight, easy-fitting package and suits families who want a helmet at a more basic specification level:

Another route is a youth full-face helmet for children who do more aggressive riding, which offers chin and face coverage the open-face Scamp does not. Read the sizing and fit guidance carefully before choosing a full-face model, since these helmets are heavier and must fit snugly.

For families who want a different youth helmet with a similar fit system, the Trek Tyro is another option to compare.

FAQ

Is the Giro Scamp MIPS II good for beginner riders?

Yes, it is generally suited to beginners on paved paths, quiet streets and easy trails. Its light shell and adjustable fit make it practical for children who are still learning balance and braking. Supervise new riders closely and make sure they know how to stop safely.

What size should I buy for my child?

Measure head circumference and compare it to Giro’s current size chart. Do not rely on age alone. If the measurement falls between sizes, try both on and choose the one that sits level and snug without pressing hard on the head.

Does MIPS make a helmet crash-proof?

No. MIPS is designed to reduce rotational forces in certain angled impacts, but no helmet can prevent all injuries. The best protection comes from correct sizing, proper fit, consistent use and replacement after crashes.

How do I know if the helmet fits correctly?

Check that it sits level on the forehead, 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 underneath. Ask your child to shake their head; the helmet should stay in place.

Can my child wear this helmet for mountain biking?

It can be used on light, non-technical trails with supervision. For jumps, drops, downhill or aggressive trail riding, a full-face youth helmet offers protection the open-face design does not provide.

How often should I replace the helmet?

Replace it after any significant impact, even if there is no visible damage. Also follow the manufacturer’s guidance on age-based replacement, which is commonly several years from the date of manufacture. Check the helmet for cracks, loose padding or worn straps regularly.

Where is the safety certification on the helmet?

Look for a sticker or label inside the shell. It should state that the helmet meets the US Consumer Product Safety Commission standard for bicycle helmets. If you cannot find it, do not use the helmet.

Final Verdict

Is the Giro Scamp MIPS II worth buying?

For casual youth riding on paved paths, neighborhood streets and gentle trails, the Giro Scamp MIPS II is a solid choice. It adds MIPS rotational protection to a lightweight, ventilated shell with a dial-style fit system that makes adjustment straightforward. Its main limitations are the open-face design and the need to confirm that your child’s head measurement fits the Small size. Measure carefully, confirm the safety label, and choose a full-face helmet instead if your child rides aggressively.
