Mavic’s latest helmet, the Deemax MIPS, is designed for trail and enduro riders.
The helmet offers decent levels of head coverage, a MIPS liner and plenty of vents.
Finishing touches include rubberised sunglasses ports, an adjustable visor and fixed straps.
Updated since Alex Evans first reviewed it in 2020, I liked the Deemax MIPS a lot in testing. It’s a comfortable helmet that feels light on the head, offers a high level of ventilation and looks good.
Mavic Deemax MIPS features and performance

The distinctive angular cut-out over the ears is a visual nod to the low drop of the shell below the skull, boosting the area of protection offered on this all-rounder MTB helmet.
There’s temple protection too, ahead of the ears, in line with other enduro-focused half-shells.
Inside, onto which the comfortable Coolmax pads are attached, the MIPS liner helps protect against rotational impacts.
No fewer than 19 vents litter the shell, with moderately deep internal channels helping pull cool air over your head to the large exhaust ports at the rear.

The three vents over the brow are particularly good at cooling your head, while there’s a nod towards anti-fogging with small cut-outs on the inside edge of the shell, over the brow.
While I tested the helmet predominantly with mountain bike sunglasses, Mavic says it’s compatible with MTB goggles too. Such features, in my experience, help reduce fogging.
Combining these vents and internal channels makes the Deemax MIPS one of the cooler helmets of this ilk I’ve tested.
Full of features

Mavic has given the Deemax MIPS a large three-position visor, there to keep the sun from your eyes and rain from your lenses.
The visor is relatively high, and so I never moved it from the lowest position. Even there, I found it unobtrusive, to the point where I wanted it a touch lower to better keep the sun from my eyes.
Pushed up, there’s ample room for goggles to sit, if that’s how you stow them on a climb.

On the top of the helmet, there’s a pair of rubber covers over the profile of the lid, under which the arms of your sunglasses can be pushed to store them safely.
This can be done under the visor or over the back of the helmet.
The storage is secure, although I found it tricky to locate the arms under the covers, especially while pedalling.
Fit and forget

The Coolmax pads are comfortable and have resisted smelling so far. They soak up some sweat, but fortunately don’t seem to drip it too readily onto the lenses of your sunglasses.
The Ergo Hold SL+ cradle is also padded. Its turnwheel offers fine-tuning of the fit, and despite a less-rounded internal shell shape, its fixed points being at the temple means the helmet should fit all but the roundest heads.
There’s multi-point cradle-height adjustment, too.

The straps are fixed in place, which I like. They’re anchored in a sensible position and the strap splitter is low-profile and comfortable against the face.
The buckle is a simple click mechanism. On a helmet at this price, I’d rather see the superior magnetic Fidlock buckle, which is easier to use with one hand.
You’ll need to pay an extra £20 / $21 / €20 for this, as found on the Deemax Pro MIPS.
My Medium helmet came in at 405g, a touch over the claimed weight of 390g.
Mavic Deemax MIPS bottom line
![Mavic Deemax mountain bike helmet](https://c02.purpledshub.com/uploads/sites/39/2024/06/Mavic-Deemax-helmet-vents.jpg?webp=1&w=1200)
With a competitive weight and excellent ventilation, the Deemax MIPS is a solid choice for those looking for a do-it-all open-face helmet.
The lid has plenty of features, most of which are great. I’d like the glasses storage to be a little more intuitive to use, and in low sun, the visor a little lower down.
But, otherwise, there’s little to complain about and the Deemax MIPS is likely to be a regular sight on my head this spring.
