KASK Rex Helmet Review [2022]

KASK Rex Helmet Review

Mountain biking has been considered a dangerous sport for decades because of the tough terrains and up-hill unsteadiness. As the manufacturing of bike helmets started, cyclists were pleased to have some impact protection while riding up murky mountains.

However, traditional bike helmets are designed in a low-profile style and do not cover the side or the rear of the head which compromises safety. To combat the inequality, KASK recently launched their Rex mountain bike helmet which offers incredible head coverage – from the temple to the base of the skull.

In this guide, we go into complete detail of the incredible engineering that KASK Rex bike helmet boasts along with the pros and cons of buying it. 

KASK Rex Helmet Features Review

When picking up an MTB helmet, you really have to dig into the specs of the helmet to ensure that it offers the best it can in terms of impact protection, durability and coverage. We’ve reviewed below every detail you’d need to know before zeroing in on the KASK Rex bike helmet.

Design and Aesthetics

The KASK Rex bike helmet comes in six different bright colours, including a matte black and a stark white. The neon red and fiery orange add to the reflective visibility of the helmet making it a perfect pick for nighttime cyclists.

Shell Material and Safety

KASK Rex is constructed using high-quality polycarbonate that is fully in-moulded to shave off some weight without compromising the impact protection of the bike helmet. 

Under the shell is a layer of plush EPS foam that absorbs shock upon sudden impact and disperses it so the head isn’t injured and not a scratch is in sight.

The deal-maker though is definitely the low back of the MTB helmet. Not only does it protect the top and side of the head but it extends down to the base of the skull so the head is cradled comfortably and positioned perfectly inside.

Maximising coverage is a high-pivot peak at the front of the helmet that adjusts easily to protect against the sun’s glare.

Size and Fit

The KASK Rex MTB helmet is available in two sizes: medium and large and fits head sizes up to 62cm. Though it isn’t available in a size smaller than 52cm, the fitting system is adjustable and can accomodate head sizes till 50cm if the shape sits according to the contour of the head.

Speaking of the fitting system, the Rex helmet features the OctoFit system which adjusts the helmet to the head in an exact fit so the weight is distributed evenly around. 

Ventilation

The second best feature of the KASK Rex enduro helmet is its incredible aerodynamics. It is fitted with not one, not even ten but 20 massive vents that air out the temples, the top of the head, even the back of the neck and still manage to be whisper-quiet on the road. 

Maximising ventilation is the CoolMax padding that bulks up the interior, protects the head from impact forces and can be removed easily to wash or replace. The KASK Rex also features a brow pad that wicks away moisture and prevents sweat build-up.

Retention System

The KASK Rex MTB helmet is further optimised by the secure retention system that surrounds the head like a ‘halo’ so the head is positioned perfectly and the helmet doesn’t fly away in the wind. It can be adjusted using two foam pads at the rear end.

It doesn’t end there, along with a comfortable faux leather chin strap, two side straps are present with strap guides to adjust the height of the helmet and fit it perfectly on the head. Also, it is waterproof and prevents sweat buildup.

Weight

The KASK Rex MTB helmet weighs 0.59 lbs, lighter than most enduro helmets but just as impact protective. Coupled with its incredible ventilation system, the cooling interior and the exact fitting, the bike helmet feels feather-light on long distance rides and keeps the cyclist safe against accidents.

Comfort Level

The KASK Rex MTB helmet defines comfort through its massive vents, sweat-proof padding as well as a chin strap that does not scratch stubble or skin. Also, it can be worn with goggles easily. In fact, the bike helmet comes with a small clip on the back to securely hold the goggle strap in place when enduro-riding.

Performance Limitation

Despite the multitude of features in-built in the bike helmet, the KASK Rex has been opted out of choosing because of the lack of rotational impact protection. Safety technologies like MIPS have been introduced in MTB helmets (at the same price point) which keeps the Rex from moving forward in the industry.

Price

The KASK Rex can be purchased for $245 which for a MTB helmet is quite steep, especially considering MIPS isn’t integrated. However, at this price, the Rex offers full coverage which is rarely seen in a bike helmet for enduro riders. The helmet may not be a must-have but it is true to claim.

Final Thoughts:
