I’m currently eyeing a used but practically brand new Kask helmet online that is being sold for nearly 50% off. I’m very tempted to blind buy it but I’ve never tried a Kask, although I’ve been wanting one for a long time.
There is just one problem. According to my tape measure at home, my head circumference is 55cm while the helmet is a 56cm.
How do Kask helmets usually fit? Do they run small/large? Is there anything I can do to safely adjust the fitting for that extra 5cm?
