How to choose the right size of SMK helmet? All helmet brands have different sizing as compared to others. Please see the size chart for each product and choose size as per the chart.
How should the helmet fit? Your helmet should fit snugly and square on your head. Make sure that it is not tilted too far back or forward on your head. Cheek pads touch, but do not press uncomfortably. Make sure there are no gaps around your forehead or back of the neck. With the straps securely fastened, shake your head slightly from side to side and back & forth. If it moves or feels loose, then it is too big. Also remember that the inner liner will compress a little with use, so a new helmet should fit as tight as you can comfortably wear.
How to clean SMK helmets? You can use helmet sanitizers for cleaning effectively and quickly. Please check our blog section for detailed helmet cleaning & maintenance.
What if the helmet does not fit me? You can always exchange the product for the size needed. Please connect with our technical team or refer to our size exchange policy.
Helmet Sizing Guide
1. To measure your head size, wrap a tape measure horizontally around your forehead as shown in the image above. Take several measurements. The largest measurement you take is the measurement to go by.
2. If you do not have a measuring tape, just take a thread or a thin string and measure it in the same way as above. Use a scale to measure the length by placing the string on it.
3. Select the helmet size as per chart closest to the measurement value. Refer size chart for each brand separately as sizing & fit of the helmet may differ from brand to brand.
