Limar Air Atlas MIPS helmet review: The latest aero helmet from a lightweight specialist

The best number on the scale only comes with the fairing removed; is anyone going to do that?

Cyclingnews Verdict

The Limar Air Atlas MIPS is a lightweight helmet but making it the lightest aero helmet I've tested requires removing a fairing and impacting aero performance. It's a marketing trick and it seems unlikely anyone will actually do it but the helmet might be worth a purchase anyway because of the comfort, wide range of adjustment from the rear cradle, and easy to clean padding.

Almost every modern helmet today uses Expanded Polystyrene (EPS) foam but it wasn't always like that. The innovation came to market in the mid-1970s and at the time, there weren't a lot of companies pushing the technology forward. While the bike industry began coalescing around the idea, Limar's parent company, Manifattura Polistirene Espanso (MPE), was already an experienced provider of shaped polystyrene for other applications. By the time Limar produced the brand's first bike helmet in 1988, the company already had over 20-years experience.

Testing scorecard and notes
Design and aestheticsIf you’d like to keep a little less flashy, the black or blue matte is plenty subtle enough you could pair it with a wide range of bikes. Go for the pink option with waves if you want to stand out more. I’m a fan of the style. 8/10
ComfortI’ve experienced helmets with better padding but the Air Atlas does a good job disappearing once you get it set right for you.8/10
VentilationThe more time I spend with aero helmets, the more impressed I’ve been. Limar has carefully modelled airflow through the helmet and this is a standout for ventilation.10/10
SafetyMIPS is a good sign but a lack of Virginia Tech testing always casts a shadow that is difficult to get past. 6/10
ValueStandard pricing for aero helmets is £229.99 / $299.99 and Limar is charging a premium for the Air Atlas with no obvious reason why.6/10
