How do you determine your ski helmet size?

To choose the helmet, you need to determine the size of the ski helmet that will be suitable for you. This process is vital since the wrong measurements can ruin the size of your helmet. You can easily determine the right size for your ski helmet following the steps below:


The first step in determining the size of your ski helmet is to find a suitable measuring tape. You can use a fabric measuring tape for this.

You can also use a thread to measure the circumference of your head and then later measure the length of the thread with a regular scale.


Once the measuring tape is ready, you can now measure the circumference of your head. For this step, it is better to take someone’s help. They need to be set slightly above the brows. Then take the measurements.


When all the measurements are ready, look for a ski helmet according to those sizes. Put on your helmet and check for proper fit. If all the measurements are correct, they should fit perfectly.


Now check for gaps. If all of the linings within the helmet are snug against your head and there are no gaps, the helmet is a perfect fit. A correct size helmet should fit snug on your head.

Ski Helmet Components:

Ski helmet has been a crucial gear for the sport for a long time. In this long period, ski helmets have changed a lot. From technology to comfort, there have been massive changes in the qualities of these helmets.

ABS Hard Plastic outer shell:

The outer shell is the hardest part of the ski helmet. They consist of tough plastic. These plastics although, are very hard, are very light in terms of weight. The outer shell is made of ABS plastic.

 This outer shell forms the main structure of the helmet as well as acts as the primary protective layer.

Shock-absorbing EPS foam liner:

Under the ABS plastic shell is a layer of shock-absorbing foam. An EPS foam liner resides here to absorb shocks and provide added security. This layer absorbs all shocks both from skiing or when you fall over.

 When buying a helmet, make sure there is a shock-absorbing layer in the helmet. This layer is vital for the protection of your head.

Comfortable foam liner:

That is why this layer provides warmth and overall comfort while wearing the helmet. This layer is removable, and you can wash them as well.

Comfortable ear pads:

There are soft, foam ear pads to cover the ears in the ski helmet. These ear pads provide abrasion resistance during any accident. In addition, they also keep the ears warm.

Protective goggles:

Some ski helmets have pre-adjustable goggles. These goggles offer eye protection. They also improve visibility in snowy circumstances.

Quick-lock chin strap:

There is an adjustable chin strap attached to the helmet. You can tighten the helmet using this chin strap. This strap also provides a bit of protection for the chin.

Ski Helmet Construction:

As a ski helmet is a safety gear, these helmets have multiple durable layers of safety materials. Here’s how manufacturers construct a ski helmet:

The core contains layers of polystyrene and shock-absorbing foams. On top of them, there is a layer of soft foam lining is.

Air vents:

After infusion of the core and shell together, the base of the ski helmets is ready. Then air vents are made on the base of the helmets. These vents help in air ventilation inside.

Paint and finishing:

After cutting the air vents on the shell, the helmet is ready for painting. At this stage of the construction, the helmets are painted and get branding logos on them.

Earpads and chin strap:
