Giro Manifest Helmet Review

For years, Swedish helmet companies have engineered innovative technologies to improve impact protection, enhance ventilation and maximise comfort of the cyclist but most of the helmets have been targeted to a specific niche of cycling whether it be MTB riding, long-distance cycling or off-road trail riding.

The Giro Manifest bike helmet comes out at the top of the industry and features incredible engineering that works for all cycling disciplines. In this guide, we cover the specs of the helmet, provide details on how it improves the comfort of cyclists as well as how it could be improved for better experience.

n this breakdown, we review how a single feature of the Giro Manifest bike helmet takes the safety and convenience of the helmet up several notches and how it has surpassed expectations of pro and novice cyclists.

Shell Material and Safety

The Giro Manifest bike helmet is constructed of an in-mould tough polycarbonate shell fused with the interior foam liner for improved durability and lightweight structure.

Along with the exterior shell, a MIPS shell is engineered in a ball-and-socket design that not only removes the use of a hard plastic slip plane technology but also improves rotational impact protection via the movement of the outer shell against the inner liner.

To further improve the structural integrity of the Giro Manifest bike helmet, the company’s exclusively-made Aura Reinforcing Arch is added and it helps enhance the airflow to the vents as well.

Also, the interior is equipped with a dual-density EPS layer for absorbing shocks at high-speed impacts and a low-density EPP foam for low-speed impacts.

Size and Fit

The outperforming Swedish bike helmet is available in three different sizes: small, medium and large and comfortably fits head sizes between 51cm and 63cm.

The Spherical Technology in the Giro Manifest bike helmet is enhanced by the addition of a dial adjustment system which works together with the dual-density EPS foam and allows horizontal positioning of the helmet to the head. 

The triangle webbing of the side straps can then be pulled to buckle under the chin and securely hold the bike helmet to the head so it doesn’t fly off in the wind. The straps are made of faux leather, sit smooth against the skin and do not tangle with stubble or saturated with sweat.

Design and Aesthetics

The Giro Manifest bike helmet is designed in a streamlined low profile that helps reduce wind drag, cut down on wind whistles and optimise the ventilation of the helmet at every riding position – even a downward tilt!

Also, it is available in 11 different colourways which are mostly muted tones so cyclists of every age and experience can enjoy the sleek bike helmet. 

Ventilation

The Giro Manifest bike helmet is equipped with a total of 19 large vents that surround the front, top and back of the helmet to circulate cool air to every part of the head and expel funky air out the back after cooling down the neck.

It is facilitated by the addition of an internal air channelling system that circulates air down to the scalp and prevents head sores, heat exhaustion and sweat build-up. 

Coupled with the interior padding, the Giro Manifest bike helmet ensures sweat doesn’t run down, obstruct vision and compromise head safety.

Retention System

The feature-fed Giro Manifest bike helmet also boasts the addition of the company’s patented Roc Loc Trail Air retention system which works with the horizontal adjustment from the rear dial to vertically adjust the head and push it deeper inside so the helmet isn’t sitting on top of the head.

This also allows better coverage of the head and protects the neck from gravel rash as well.

Weight

The Giro Manifest bike helmet weighs 0.74 lbs which for a MIPS integrated lid is decent but for a bike helmet is more than average. However, the company’s patented fitting system, Roc Loc 5+ Air Trail, allows cyclists to vertically position the helmet better and distribute the weight evenly so it feels lighter on the road.

Comfort Level

The Giro Manifest bike helmet enhances comfort of the cyclist by stitching a layer of plush XT2 padding that is antimicrobial, removable and washable. Also, the helmet can be adjusted to an exact fit so riders practically forget that they are wearing something on the head.

Performance Limitation

The Giro Manifest bike helmet delivers all its claims perfectly and not a hair is out of place when the cyclist is wearing it. However, the more-than-average weight of the helmet may strain petite heads if not fitted well enough and this may slow them down or leave excess room inside.

Price

The Giro Manifest bike helmet costs around $260 and though this isn’t budget-friendly, it is decent for a MIPS integrated helmet that features dual-shells for safety and coverage, large vents for breathability, a patented fitting and adjustment system as well as a dual-lining of EPS foam for high and low speeds.
