The measured head circumference decides the size, not the S/M/L label · review
A 260 g (9.2 oz) commuting and road helmet in 58 to 60 cm (22.8 to 23.6 in), with twenty-six vents, in-mold EPS construction and three declared safety markings.
Our conclusion The only helmet on this page that publishes its own weight — 260 g (9.2 oz) — along with a circumference range in centimeters, twenty-six vents, three declared safety markings and a 360-day warranty. It is $26.99, a fifth of the Giro, and what it does not have is MIPS or any rotational-protection layer at all.
A commuting and road helmet weighing a published 260 g (9.2 oz), in 58–60 cm (22.8 to 23.6 in) (called Large), with 26 air vents, a high-density EPS core in in-mold construction, a snap-on detachable visor, a rear dial, washable padding and a 360-day warranty. $26.99.
“Weighing in at a mere 260 g (9.2 oz).”
That matters on this shelf for a reason beyond the number: the introduction to this page used to say that no helmet in the hub published a weight at all. Every other helmet in this American survey gives only a shipping figure — 320 g (11.3 oz), 380 g (13.4 oz), 399 g (14.1 oz), and 671 g (23.7 oz) for the Giro, all of which include the carton.
Two hundred and sixty grams is a genuine road-helmet weight, and it is the one figure here that can be compared with anything.
“Fully complies with U.S. CPSC and ASTM standards, as well as European CE safety regulations.”
Three, where the Giro and the OutdoorMaster on this page name none and the Schwinn names one. The BATFOX names three as well, and goes one better by citing ASTM F1447 by number.
These are manufacturer declarations, which is all a comparison page can report. Nothing here assesses how a helmet performs in a crash, and the buying advice on this shelf is worth repeating: a helmet is a replace-after-impact item by every maker’s own instructions.
BATFOX 18, Schwinn 20 or 21, OutdoorMaster 25, Favoto 26, Giro not stated.
“Twenty-six strategically placed cooling vents… actively pulls heat and humidity away.” What it does not describe is internal channelling, which is what the Giro’s Wind Tunnel system adds: vents move air across a shell, channels move it across the scalp.
Vent count is the comparable figure; channelling is the one that is not published here.
58–60 cm, two centimeters.
| label | range | |
|---|---|---|
| This helmet | L | 58–60 cm (22.8 to 23.6 in) |
| BATFOX | L | 58–61 cm (22.8 to 24 in) |
| Schwinn | one size | 58–62 cm (22.8 to 24.4 in) |
Three products, three different bands, all for a head of about 59 cm (23.2 in). That is exactly why the buying advice on this shelf says to compare your measured circumference to the range and not to the letter — a 61 cm (24 in) head fits the BATFOX L and the Schwinn, and not this.
No MIPS, and no rotational-protection layer of any kind. The OutdoorMaster on this page has MIPS at $59.99 and the Giro at $119.95; this is $26.99.
That is the trade, stated plainly. What $26.99 buys is a certified, light, well-vented in-mold helmet with a published weight. What it does not buy is the slip plane.
“High-density EPS foam core and rugged in-mold construction.”
In-mold means the polycarbonate shell is bonded to the foam in the mold rather than glued on afterwards, which is lighter and does not delaminate. It is the standard construction at this price and above, and the 260 g (9.2 oz) is consistent with it.
The Giro adds a hard outer shell over the in-mold layer; the BATFOX describes the same in-mold fusion in one sentence.
Not a year — 360 days. Only the Bone phone mount elsewhere on this site publishes a comparable figure, and no other helmet here publishes any.
No MIPS or equivalent, no internal channelling, no EPS thickness — where the brand’s own helmet already published on this shelf states 20 mm — no strap material, and no statement of which of the three markings the actual shell carries.

For a vented road helmet, yes, and it is the only figure on this page that can be checked against anything — every other helmet here publishes only a shipping weight with the carton included, from 320 g (11.3 oz) to the Giro’s 671 g (23.7 oz). A 260 g (9.2 oz) in-mold shell with 26 vents is a genuinely light helmet, and the construction is consistent with the number.
Measure it. This Large is 58–60 cm (22.8 to 23.6 in); the BATFOX Large on this page is 58–61 cm (22.8 to 24 in) and the Schwinn is sold as one size covering 58–62 cm (22.8 to 24.4 in). A 61 cm (24 in) head fits two of the three and not this one. The buying advice on this shelf exists for exactly that: compare your measured circumference, taken just above the eyebrows, to the stated range rather than to the letter.
That is the real choice on this page, and it is yours to make. This helmet has no rotational-protection layer; the OutdoorMaster has MIPS at $59.99 and the Giro at $119.95. MIPS is a slip plane intended to reduce rotational forces in angled impacts, in its makers’ own hedged words. Nothing on this page assesses how any helmet behaves in a crash — what this one gives you instead is three declared markings, 260 g (9.2 oz) and $26.99.
