Find the right size by measuring your head circumference or trying on helmets at a snow sports store. If using a measuring tape, position it slightly above the ears and about 1cm above the eyebrows. Measure the longest circumference around your head to determine your head size, and then find the appropriate helmet size by comparing it to the sizing chart on the helmet packaging.
A good skiing helmet should feel comfortable but not too tight. If the helmet can move back and forth, it is too loose. Adjust the size using thick pads and push the front and back of the helmet with your hands. If the helmet moves, tighten the chin strap: the strap should be snug against your throat but still allow you to chew food comfortably, and not too tight to cause discomfort.
Size: Choose a skiing helmet that fits your head size. If you have a habit of wearing a hat inside the helmet, you can choose a slightly larger size. Otherwise, choose a smaller size, because the liner of the skiing helmets is soft and will fit your head after a few wears. A helmet that is too big can affect the quality of skiing.
Removable and washable liner: A removable and washable liner makes it easier to keep the inside of the ski helmet clean, so choose a ski helmet with a removable and washable liner whenever possible.
High breathability: Skiing helmets with high breathability have enough ventilation ports to let in cold air and expel hot and humid air. It is recommended to choose a skiing helmet with an automatic adjustment vent, which can adjust the airflow immediately without interrupting your skiing. Closing the adjustment knob can prevent snow leakage during skiing.
Check the safety label: Check if the helmet has a production permit and if it meets national safety standards.
Check the helmet's strength: When choosing a helmet, you can turn it over and press the front, back, and two sides inward to see if it is easily deformed. If the helmet is easily deformed or soft, it will not provide good protection to the head in the event of an accident.
Try it on: The key to trying on helmets is to feel. One is whether the shape and size are appropriate, because tightness can cause pressure on the head, and even dizziness, affecting driving safety. If the helmet is too loose, it will move and fall off easily, and a slight impact can make the skiing helmet fly far away. The ideal feeling is that the entire head is in contact with the liner and the cheeks are slightly tight. But there must be no pressure on the ears.
