The measured head circumference decides the size, not the S/M/L label · review
A recreational adult helmet covering 58 to 62 cm (22.8 to 24.4 in) from one shell, with a dial, washable padding and a removable visor.
Our conclusion The cheapest helmet here at $25.59, with the widest single size band — 58 to 62 cm (22.8 to 24.4 in) from one shell — a dial, washable 360-degree padding and a removable visor. It is also the only helmet on this page to name the CPSC provision it meets, extended head coverage, and the only one to count its own vents twice: twenty in one bullet and twenty-one in another.
An adult recreational helmet for heads of 58 to 62 cm (22.8 to 24.4 in), ages 14 and up: microshell construction, an adjustable dial with side and chin strap adjustment, full-coverage removable and washable padding, a removable visor, and moisture-wicking pads. $25.59 — the cheapest helmet on this page.
| label | range | |
|---|---|---|
| This helmet | one size | 58–62 cm (22.8 to 24.4 in) |
| BATFOX | L | 58–61 cm (22.8 to 24 in) |
| Favoto | L | 58–60 cm (22.8 to 23.6 in) |
The buying advice on this shelf is to compare your measured circumference to the range, not the letter — and this is the clearest demonstration on the page. A 62 cm (24.4 in) head fits only this helmet of the three that publish a range at all.
What a four-centimeter band means in practice: the dial is doing more work. At 58 cm (22.8 in) it is wound well in and at 62 cm (24.4 in) nearly out, and the pads carry the difference. A helmet at the very top of its range has least adjustment left if the fit needs changing with a thin cap in winter.
“Complies with U.S. CPSC Safety Standard for Bicycle Helmets for Persons Age 1 and Older (Extended Head Coverage).”
That parenthesis is the detail. CPSC’s bicycle helmet standard has two test configurations — one for helmets for ages five and over, and an extended head coverage version with a lower test line, used for helmets intended to cover more of the head.
No other helmet on this page names a provision. The BATFOX cites ASTM F1447 by number, which is the other way of being specific; the Favoto names three markings without numbers; the Giro and OutdoorMaster name none.
As everywhere on this shelf, this is a manufacturer declaration we report. Nothing here assesses how a helmet performs in a crash.
“Twenty air vents keep you cool”, in the fourth bullet. “21 flow vents to keep you cool”, in the seventh.
Same helmet, same page. It is a small thing and it is the kind of slip worth noticing on a listing, because it tells you which figures were checked. The BATFOX helmet on this page has a comparable slip: its bullet heading says three sizes, its sentence says two, and it lists three.
Either way this sits mid-field: BATFOX 18, Schwinn 20–21, OutdoorMaster 25, Favoto 26.
“Microshell construction for lightweight durability.”
A microshell is a thin plastic skin taped or bonded over an EPS liner — simpler and cheaper than the in-mold construction the Favoto and BATFOX describe, and much simpler than the Giro’s two-piece hard shell with a fused lower wrap.
What a microshell gives up is edge durability: the bottom rim of the foam is less protected, which is where a helmet meets the floor of a car boot. At $25.59 that is the trade, and the listing does not pretend otherwise.
“Full-coverage padding surrounds the head in 360° comfort and can be removed and washed”, plus moisture-wicking pads.
On a recreational helmet worn daily this is the feature that decides whether it is still pleasant to put on in year two. The Favoto and BATFOX helmets on this page say the same; the Giro and OutdoorMaster do not mention washing.
No rotational-protection layer, like the Favoto, BATFOX and Exclusky on this page.
No weight at all — not even a shipping figure on the record. This is the only helmet in the group with none.
And the fifth bullet: “Schwinn is the original American bike brand. We’ve spent over 130 years building the bicycle industry… each product is designed in Madison, WI.” That is a statement about the company.
No weight of any kind, no MIPS or equivalent, no EPS thickness, no vent count that agrees with itself, and no strap material. What it does publish — a four-centimeter circumference band and a named CPSC provision — is more than two helmets here manage between them.

It covers 58 to 62 cm (22.8 to 24.4 in), which is the widest band on this page — a 62 cm (24.4 in) head fits nothing else here that publishes a range. What four centimeters means is that the dial carries the difference: wound well in at 58 cm (22.8 in) and nearly out at 62. If you are at the very top of the band, there is little adjustment left for a thin winter cap, and that is worth knowing before ordering.
A CPSC test configuration. The US bicycle helmet standard has two: one for helmets for ages five and over, and an extended head coverage version tested to a lower line on the headform, for helmets meant to cover more of the head. Schwinn naming the provision is more specific than any other listing on this page except the BATFOX, which cites ASTM F1447 by number. It is a manufacturer declaration, and nothing on this page assesses crash performance.
The listing says both — "twenty air vents" in its fourth bullet and "21 flow vents" in its seventh, on the same page. Nothing turns on one vent; what it tells you is which figures on a listing were checked. Either number puts it mid-field here, between the BATFOX’s 18 and the Favoto’s 26.
