Bell Full-Air Mips review

Bell's Full-Air Mips is a full-face helmet in the brand's US mountain-bike catalogue, not a half-shell with an interchangeable chinbar. The observed style is 100000001500000026 in Matte Black / L, SKU BL-7203665. Bell's exact US page presents it for climbing and descending, names several standards, and lists a mixture of ventilation, visor, pad and camera/light-mount features. This is a document-based assessment: I have not ridden, fitted, weighed or crash-tested the helmet.

A full-face format with removable pads

The distinction that matters first is the shell. Bell calls this a true full-face helmet. Its page says cheek-pad sections can be removed to increase airflow or added for more security, and it separately lists removable temple pads. Those statements describe pad changes; they do not say the chinbar detaches. A shopper seeking a helmet that converts to an open-face mode should not read “modular cheek pad system” as evidence of a removable chinbar.

Bell's catalog places the model in MTB, while its description talks about pedaling to the top and descending. The exact page lists ASTM F1952-15 Downhill and ASTM F2032-15 BMX, alongside US CPSC, NTA 8776 (E-Bike), CE EN 1078-2012 and AS/NZ 2063. This is a list from Bell, not a laboratory result produced for this assessment. The page doesn't give an age-specific CPSC statement, so I don't import age wording from other Bell models. Confirm the markings on the actual helmet and follow the instructions that come with that exact unit. Bell's general manual cautions that some helmets may not suit extreme riding and says the inside label identifies intended use; the Full-Air page's downhill language is a model-specific detail to compare against that label, not a reason to ignore it.

Four chart bands, one important discrepancy

Bell's US size-chart data lists S at 51–55 cm, M at 55–57 cm, L at 57–60 cm and XL at 60–63 cm. The neighboring bands meet at 55, 57 and 60 cm, so a number at a seam can appear in two sizes. A chart is a screening aid for selecting sizes to try, not proof that a particular shape, pressure pattern or retention adjustment will work for a particular head.

There is a source conflict in the L row: the chart's metric cell says 57–60 cm, but its imperial cell says 21 3/8–23 1/2 inches. Those endpoints do not agree when converted. Because the finder asks for centimeters, its L plan follows the displayed centimeter interval, while this review flags the mismatch instead of silently reconciling it. Check the current chart, selector and physical size marking before choosing L. Bell's linked instructions say to measure level above the eyebrows, repeat the measurement and use the larger reading; the page also advises sizing up when directly between sizes. Try the helmet on and check position, straps and retention as the manual directs.

Useful hardware—and claims with no measurement behind them

The listed equipment is specific: Advanced Mips Evolve, dual-density EPS, an in-mold polycarbonate shell, a two-position Flying Bridge visor intended for eyewear or goggle storage, a removable washable liner, Sweat Guide padding, a Fidlock magnetic buckle, removable temple pads and a breakaway under-visor action-camera/light mount. Bell says the cheek-pad system can be configured for more airflow or security. The page does not name a numeric vent count, provide an airflow or cooling measurement, specify a head-shape profile, or identify a dial-based fit system. It also provides no weight figure on the exact US page. “Lightweight” and “superior ventilation” are manufacturer descriptions, not measurements I can verify here.

Mips Evolve is the system the page names. It is not Bell's Spherical Technology, so the model does not satisfy a finder choice that specifically requires Spherical/Mips. That distinction can matter when comparing Full-Air with a documented Spherical full-face such as the Giro Coalition Spherical style 027; that Giro page's review explains a different rotational design and a separate US-CPSC evidence gap. Neither system label is a personal protection guarantee, and the two model pages are not comparative crash tests.

Who should put it on a try-on list?

It is a reasonable research candidate if you want a full-face mountain-bike format, the exact Bell page's US CPSC statement, Mips Evolve, and the published size bands—and if you can verify the chart discrepancy and the fit in person. The visor storage, Fidlock buckle, washable liner and under-visor mount are practical details to check against your eyewear, camera/light and care routine. Before treating the accessory mount or cheek-pad options as a reason to buy, confirm which pieces are actually included in the exact offer: Bell cross-lists replacement cheek pads and a visor, and those separate accessories are not proof of package contents.

Look elsewhere if your must-have is an open-face helmet, a documented Spherical/Mips system, a stated numeric weight, a confirmed adjustable fit mechanism, or an unambiguous L-size chart. The US page doesn't establish those needs. Bell's recall page checked for this assessment names other helmet families, not Full-Air Mips; the CPSC bicycle-helmet recall-category request available to this research returned HTTP 403. That dated manufacturer-page screen is not a unit-history clearance or a promise that no later notice exists.

Primary material reviewed

• Bell's exact US Full-Air Mips style page and its linked US helmet size-chart library.
• Bell Bicycle Helmet Owner's Manual for general measurement, use-label and fit-check guidance.
• Bell's US recall notice, checked 2026-11-01. The category-level CPSC page was inaccessible in the preserved 2026-10-31 request, so no agency recall clearance is claimed.
