Brand Giro
Model Year 2019
Road Helmet Type All-round helmet
Weight 270 grams
Extra protection Yes


The Giro Aether MIPS is a revolutionary helmet considering its head protection in a fall. With this helmet, Giro created a build that significantly reduces rotational forces that occur during an impact. In addition, the shell is equipped with the MIPS technology, which greatly reduces chance of head injuries after a fall.

The technologies mentioned above don’t impact the ventilation properties of this helmet. Aside from the vents visible on the outside, this helmet also has internal vents. This will keep your head cool even on the hottest days. In addition, the Giro Aether MIPS has the Roc Loc ® 5-Plus fit system which allows you to adjust the helmet’s fit in seconds.

Exemplary service from Mantel!!!

This is a sensational helmet. I did a lot of research before purchasing & it's true what pretty much all the other online reviews say, this is a stunning helmet. Spherical MIPS, comfortable, fast & it looks great too! In addition to all this, the service from Mantel was absolutely exemplary! Great communication & super fast delivery. I will definitely be a returning customer. Thank you Mantel and thank you for designing the helmet Giro

Can't fault it

Great price and speedy delivery from Mantel. I can't find anything to fault with this helmet. It's very light and has many ventilation holes which work well in hot weather. It's very comfy straight out of the box, all I had to do was adjust the strap and take the label off. I bought it on the back of all the positive reviews in the press (and reviews from people who had bought it), they weren't wrong.

Can tell difference with this helmet

Purchased primarily for safety - but weight and looks a big factor. Only one slight niggle is (at least for me) wearing cycling glasses with it is a little challenging to fit in properly around the straps. Cracking helmet though - half weight of previous. Pricey too - but mantel deal twisted my arm... Very comfortable and hardly know you're wearing it.

Detailed product description

In-Mold Construction:
The In-Mold Construction combines a sturdy polycarbonate outer shell with a shock-absorbing foam lining on the inside. Due to the fusing process it’s possible to create an efficient ventilation system, which allows the In-Mold helmets to be lighter and more cooling than traditional helmets.

Wind Tunnel Ventilation:
Giro helmets were designed with the help of Giro’s Wind Tunnel ventilation system. This system combines active vents with internal exhausts. This combination provides the cyclist with cool, refreshing air on and around their head, while warm and stale air is disposed of. The innovation of these vents turned out to be a huge success. Cyclists were immensely positive about it, they noticed a new air flow around their head which kept them cool!
