Beyond fit, this is the number one thing I look for before buying either a goggle or helmet. In reality, the top of the goggle and rim of the helmet often don’t line up, leaving a gap that’s cold and dorky. In general any goggle should work with any helmet. Some ear pads are ready to accept the aftermarket “chips.” This means there’s a zipper-access a hollow area inside the earpad. There are also new communication devices, like Aleck, that allow use a chip to enable walky-talky-style chatting with buddies. Yeah, you could just wear ear buds, but it’s much more comfortable to stream music from your phone into speakers in the ear pads of a helmet. If you love capturing your runs it’s a handy feature to have. Some helmets come with a pre-installed binding for mounting a GoPro or other POV-style camera. These are great for regulating your temperature, as long as the lever is easy to find and easy to use with gloves on. Close-able vents have a valve or lever that opens and closes them. Permanent ones are open all the time - you want these around the goggles to help with air circulation. These are the holes in the helmet that promote airflow to the goggles and your head. You can always check by looking inside the lid for an ASTM or CE sticker. Most stores will only carry certified helmets and it should be mentioned in any online store. The standards differ in details but both ensure a high level of protection. Most helmet manufacturers build their helmets to comply with one of two common safety standards, U.S.-based ASTM F2040 or the European CE EN1077. Bottom line: don’t pick a helmet based on construction. Plus these days many manufacturers combine the two techniques on different parts of the same helmet. For most of us, the differences are insignificant. This is the preferred method for combining multiple densities of protection. Injection-mold bonds EPS foam to the shell. In-mold adheres the shell and shock absorbing material in a single process. There are many ways to put the three pieces together, but they basically break down into two processes. This is typically a high impact ABS plastic, but it can also be carbon fibre and other tough materials. It also holds the graphics or color of the helmet. Its primary functions are to shield against sharp things stabbing into the foam, spreading out the impact force throughout the lid, and deflecting snow, rain and wind. You should always replace a helmet after a big crash. This can damage the helmet's integrity, but doesn’t always show up as cracks or deformities. It converts kinetic energy by either absorbing and rebounding or crumpling. In a fall this is the part of the helmet doing most of the protecting. It’s usually made from some sort of EPS, but there are plastic tubes and various other materials in use. This is the part that does most of the impact absorbing in a crash. The design specifics vary - generally, it’s a slippery layer between the foam and the liner. Mips is the brand name of the most common system, but there are proprietary versions. The best ones encircle the head.įinally, in many helmets, there’s an extra protective feature that allows the head to move within the helmet structure to absorb rotational forces. These keep ears warm and store audio and communication chips (more about that in a bit). The best helmets have a removable liner so you can wash it regularly and remove it in warmer weather. Usually, it offers a bit of insulation and has a wicking liner that pulls moisture away from your hair and skin to keep you warm. This is the part that interacts with your head. But there is a basic three-layer formula. Manufacturers play around with lots of different materials, designs and engineering to make helmets safer, lighter and more comfortable. The Best Ski Poles of Winter 2022-2023 The anatomy of a helmet It’s going to help protect you in a crash, but it’s not a get-out-of-injury free card. In other words, think of a helmet more like a seat belt and less like a crash pad. And one theory for why brain injury occurrence hasn’t changed in skiing, despite a steady increase in helmet use, is that wearing a helmet increases the wearer's perception of safety, so they take more risks. At high-speed head-on collisions, helmets offer limited protection. All together they help protect the head from abrasion and the brain, neck and spine from traumatic injuries.īut a helmet can only do so much. And finally, in an increasing number of helmets, a slippery liner allows the head to rotate within the helmet to soak up some of the rotational forces that often do the most damage in a crash. The hard outer shell deflects sticks, rocks and ice and then disperses forces throughout the structure. Helmets protect your noggin in several ways. What to know before you buy a ski or snowboard helmet How do ski helmets work?
