Bern Watts 2.0 Adult Bike Helmet with Brim - MIPS Safety Technology & Adjustable Compass Dial - Certified for Cycling, Skateboarding & Roller Skating - Perfect for Urban Commuting & Outdoor Sports

After researching, searching through many reviews, and trying many helmets I’ve decided on this bern watts 2.0 helmet. This helmet is lightweight and offers good ventilation. The adjustment dial functions smoothly and all parts seem to be of good quality.My head measurement is 22 1/4 inches (56 1/2 cm). I went with the small. The fit is good with very little room to spare. With the adjustment dial maxed out then tightened down 1 turn the helmet fits snugly. The straps are adjustable and had to be set to the maximum length for a good fit. I was having trouble finding a helmet as I’m right between a small and medium. Most mediums were too loose and shifted around a lot once tightened down. Some smalls were too tight. If your head measures anywhere over 22 1/2 inches the small will not fit.I am happy I went with the size small. It fits well with adjustable velcro padding on the top, rear adjustable strap, and along the forehead. The helmet doesn’t look too bulky. Some reviews mentioned that the finish shows scratches easily. This is true but this is not a concern to me. There is a cut out in the back to flush mount a light and a screw hole to mount a giggle clip. Based on the value, quality, and comfort I highly recommend this helmet.
