SMK ALLTERRA

2 INJECTION-MOULDED EIRT SHELLS

SMK Allterra is produced in two physical outer shell sizes made from EIRT (Energy Impact Resistant Thermoplastic). This impact-resistant thermoplastic material is used by SMK to create the protective helmet structure.

The two shell sizes help optimise dimensions, weight and fit for different head sizes.

MULTI-DENSITY EPS

The internal energy-absorbing layer uses Multi-Density EPS. It is an important part of the passive protection system and is designed to absorb impact energy.

ECE R22.06 + DOT

SMK Allterra complies with modern international safety standards:

ECE R22.06 - current European motorcycle helmet safety standard.
DOT FMVSS No. 218 - US motorcycle helmet safety standard.

MICROMETRIC BUCKLE

The helmet is equipped with a practical Micrometric Buckle. This system allows the chin strap to be fastened and released quickly and conveniently while also allowing precise length adjustment for a comfortable and secure fit.

The micrometric mechanism is convenient for everyday use. It can be adjusted quickly to achieve the required strap tension and secure the helmet firmly on the head.

PADDED CHIN STRAP

The chin strap features a Padded Comfort Chin Strap with soft padding that helps reduce pressure on the skin and improves comfort during longer rides.

EXTRA-WIDE EYE OPENING

Allterra features an Extra-Wide Eye Opening that provides a broad view of the track and surrounding area.

This is especially important in motocross and enduro, where the rider needs to assess terrain and obstacles quickly.

DESIGNED FOR MX GOGGLES

The shape and dimensions of the front opening are specifically designed for use with motocross goggles. The large opening allows goggles to fit securely inside the helmet while providing a wide field of vision during off-road riding.

MX PEAK

The extended motocross peak helps protect the eye area and goggles from direct sunlight, dirt and airborne debris during off-road riding.

MULTI-POSITION ADJUSTMENT

The Adjustable Multi-Position Sun Peak Mechanism allows the rider to adjust the peak position according to riding conditions and personal preference.

REMOVABLE DESIGN

The peak can be easily removed for cleaning, maintenance or replacement. SMK offers separate replacement peaks for Allterra, including versions with graphics matching specific helmet designs.

ENHANCED AIRFLOW SYSTEM

SMK Allterra is equipped with an Enhanced Airflow System developed with the high physical demands of motocross and enduro riding in mind.

CHANNELLED VENTILATION

The Channeled Air Intakes and Exhausts system uses internal channels to direct fresh air through the helmet and exhaust warm air to the outside.

CHIN VENTILATION

Chin vents provide an intensive supply of fresh air to the front section of the helmet.

FRONT VENTILATION

Additional front air intakes increase the amount of air entering the internal ventilation system.

TOP VENTILATION

Upper vents direct airflow towards the head area and help maintain comfort during active riding.

HOT AIR EXHAUST

Rear exhaust channels help remove warm air from inside the helmet and maintain continuous circulation.

SOFT AND SECURE FIT

The Allterra interior combines softness with secure support. The close fit helps keep the helmet stable during active movement, jumps and riding over uneven terrain.

BREATHABLE HYPOALLERGENIC LINER

The inner liner is made from breathable and hypoallergenic materials, which is especially important during intensive physical activity.

REMOVABLE AND WASHABLE LINER

The inner liner and cheek pads can be removed for cleaning. This makes helmet care much easier after training sessions and active off-road rides.

MOISTURE MANAGEMENT

The fabric features Moisture Management properties that help control moisture build-up inside the helmet during intense physical activity.

ANTISTATIC FABRIC

The interior materials feature antistatic properties, providing an additional level of comfort during regular use.

HOW TO CHOOSE THE CORRECT SIZE

1. Use a flexible measuring tape.

2. Wrap it around your head above the eyebrows and ears, around the widest part of the head.

3. Compare the measurement with the SMK Allterra size chart.

4. Put the helmet on and correctly fasten the chin strap using the micrometric buckle.

5. The inner liner should make even contact with the head, while the cheek pads should fit firmly against the cheeks.

6. When turning your head, the helmet should move together with your head and should not slide independently.

7. The fit should be snug without creating painful pressure points.

Important: trying the helmet on before purchase is strongly recommended.
