We do not have a lot of choices of places to buy helmets where we live so we have to buy online. I recently asked for suggestions on different helmets on Facebook and we decided to go with the LS2 Valiant II Modular Helmet. We used the sizing chart online to determine what size to buy. After measuring my head, the chart said I should wear a Large. Every other helmet I have used I needed an XL. Again, I went to Facebook for suggestions on sizing to see of they run smaller or larger than the suggested chart size. I ordered an XL based off suggestions. I have had the helmet for about 2 weeks and it is really tight and presses on my forehead almost to the point of being uncomfortable. I can tolerate it for a while but we going on some long rides next month and I don't know that I can stand it on a 500 mile ride. Any suggestions on to make it more comfortable other than buying new helmets again? I hate to waste the money on them.
