Our review

It’s a very light helmet, but one that’s pretty expensive when compared with the competition

If you’re the kind of mountain biker who hates wearing a lid, Limar’s claim to have built the world’s lightest noggin-protector is likely to make you sit up and take notice.


The Ultralight Pro 104 is indeed 50 percent lighter on the scales than most of the competition – and that’s a difference you can feel.

With the full-circumference cradle adjusted and the straps tweaked, it’s easy to forget that you’re wearing anything at all up there, despite the minimal padding.

Ventilation isn’t as good as most, though, thanks to shallow internal channels. There are other downsides to the featherweight approach, too.

The Ultralight sits higher than most mountain bike helmets, with slightly less protection to the side and back of the head. And the adjustable peak (US: visor) only really stays put in one position.


Plus, the overall finish isn’t great for the price and suggests it’ll need careful handling to withstand the rigours of day-to-day use.
