Ski Helmet Vs. Hockey Helmet

Skiing and hockey helmets might share the same function of protecting your skull, but they have several differences. Each helmet contains features that cater to its particular activity so one is not interchangeable with the other, according to the U.S. Consumer Product Safety Commission. With either type of helmet, however, seek one that is certified as meeting safety standards.

Design and Materials

Ski helmets and hockey helmets share the same basic design but are lined with different materials. Each has a hard outer shell lined with some type of padding. The shell is a generally a durable, high-impact plastic. The lining for ski helmets is usually expanded polystyrene, or EPS. Hockey helmets come lined with foam that is single density, dual density or expanded polypropylene, known as EPP.

Features

Chin straps are a must for both helmet types, as is some type of ventilation. Ski helmets have vents positioned over the entire surface of the helmet. Hockey helmet vents are concentrated near the forehead and temple areas. Ski helmets often feature a small visor built in at the helmet's forehead area to shield your eyes from sun and snow. Hockey helmets designed for goalies have a built-in face shields or attachments that accommodate shields. Ski helmets offer some type of hardware or system that lets you attach your goggles to the helmet.

Standards

No law governs safety standards ski helmet or hockey helmets must meet, but both have voluntary standards with which they can comply. Look for an ASTM sticker inside either helmet for certification from the American Society for Testing and Materials. Ski helmets meet ASTM F2040 and hockey helmets meet ASTM F1045. Ski helmets also come with the European certification CEN 1077 or one of two Snell certifications: RS-98 or S-98. Additional hockey helmet certifications are NOCSAE ND030, put forth by the National Operating Committee on Standards for Athletic Equipment, or certification from the Canadian Standards Association or the Hockey Equipment Certification Council. Approval from the Canadian Standards Association or the Hockey Equipment Certification Council comes with a CSA or HECC sticker on the back of the helmet. CSA stickers indicate the product meets American standards with "US" or "NRTL" appearing beneath the CSA logo.

Fit

The rule for fitting ski helmets and hockey helmets is the same. The helmet needs to be snug without being uncomfortable. Make sure the helmet is tight enough that it does not slip forward, back or to either side. The helmet must sit and stay level on your head with the chin strap securely in place. Helmets come in different sizes, with measurements determined by the circumference of your head right above your eyebrows. Use a tape measure to gauge your size.
