Your needs, this model
Does it fit your priorities?
What size does Giro suggest for a 49 cm circumference?
The youth table puts 49 cm at the shared XS/S boundary: XS is 45–49 cm and S is 49–53 cm. The Scamp II page identifies XS for ages 1+ and S for ages 5+, but those age notes do not replace a careful fit check; try the exact helmet and follow its instructions.
Explore this need in the finder →Is the Scamp II the same as the Scamp Mips II?
No. The Scamp II page names Roc Loc Jr., 13 vents and no Mips feature, while the separately reviewed Scamp Mips II page names Mips Evolve Core. The two model identities are not finish variants, and the Mips label is not evidence of Spherical Technology.
Explore this need in the finder →Does the Scamp II page state US CPSC compliance?
The exact style-362 page lists CE EN 1078 and 225 g for size S; it does not state US CPSC compliance. Treat that US-standard field as unknown in this evidence set and inspect the actual helmet label if needed.
Explore this need in the finder →Scamp II is Giro's small child-oriented half-shell without a Mips system named on the reviewed page. The current US style-362 product page lists two youth sizes, a Roc Loc Jr. dial, 13 vents and 225 g for size S. It also gives different age guidance for the two sizes. Those published details help distinguish the helmet from its Scamp Mips II sibling, but they do not determine whether it fits a particular child.
Style, finish and size options
The observed catalog entry is Giro Scamp II, family style 100000001400000362. The selected color route 0877 resolves as Matte Pink/Green, with SKU GR-7202773 shown for the selected S variant; Giro also offers XS. This is a child helmet in the bicycle category, not an accessory or merely an adult finish. Its separate Mips version has a different rotational-system configuration and requires its own assessment.
Giro describes the model as intended for young or future riders, including trailer use and bicycle riding. The page says XS is designed for riders age one and older and S for riders age five and older. That language is manufacturer size guidance, not a replacement for supervision, fit instructions or checking the physical helmet label. Age alone does not decide circumference, head shape or whether a shell sits securely.
Chart values and what the single figure means
The exact page offers XS and S. Giro's youth bicycle chart lists XS at 45–49 cm and S at 49–53 cm, leaving 49 cm at the shared boundary. A measured value inside a range is only a starting point: parents should check level positioning, even pressure, forehead coverage, strap placement and stability on the child. If the shell rocks or presses unevenly, a chart match is not a reason to keep it.
Giro identifies Roc Loc Jr. as a dial system shaped for a child's head and describes a large knob for adult adjustment. That description does not tell us how the helmet will fit each head shape, and the page does not provide a head-shape profile. Giro's weight figure is 225 g for S only. It is not an XS figure, not an independent measurement, and not enough by itself to establish that one child will prefer this model over another.
13 vents, no Mips claim
The page lists 13 deep vents and an in-mold foam-and-shell construction. That is useful identifying information, but the source does not report independent airflow or cooling results. Vents cannot be converted into a comfort score without comparable testing and conditions. The Scamp II page does not name Mips. A shopper looking for a documented rotational-impact system should compare the separately reviewed Scamp Mips II instead of assuming the family name or shell shape implies the same feature.
The two Scamp models are particularly easy to blur because both use Roc Loc Jr. and offer XS/S child sizing. Their functional descriptions differ: the Mips II page names Mips Evolve Core, while the regular Scamp II page does not. Neither exact page's reviewed certification section states US CPSC compliance, so that essential filter cannot be satisfied by either entry based only on the captured pages. This is a difference in documented evidence, not a claim about the physical label on every unit.
Certification and recall checks
Giro's exact style-362 US page lists CE EN 1078 and a size-S weight but does not state a US CPSC compliance claim. That leaves the CPSC field unknown here. Inspect the physical helmet and ask for model-specific documentation if US CPSC marking is essential; do not infer it from the US storefront, age guidance or a nearby style.
The manufacturer recall page checked for this review describes a recall affecting certain Merit helmets manufactured before January 2023 and does not identify Scamp II. It is a date-specific source check, not a guarantee against a new notice. Confirm model and date markings, check current Giro/CPSC notices, follow replacement guidance after a crash and verify that the seller's exact model is the one described.
When the non-Mips version makes sense to compare
Scamp II is relevant when the child-specific XS/S range, the Roc Loc Jr. dial and the stated size-S weight are useful distinctions. The Scamp Mips II is the direct comparison if a Mips label is important; its page lists Mips Evolve Core and a 13-vent configuration, but that feature is not Spherical/Mips and its CPSC wording is also absent on the exact reviewed page. The choice should turn on real fit, source-supported requirements and the physical unit, not a broad inference that one version is safer or more comfortable.
Before choosing an offer, verify style 100000001400000362, the selected size and color, the physical labels, the fit on the actual child and the return policy. Sources include Giro's exact US style page, the bicycle size chart and Giro's recall page.
