Sinner Helmet size guide

Measuring tips

Measure the circumference of your head in centimetres around it's widest point, and use the table to find the correct size for you.

Once your helmet arrives try it for size. When the straps and pads are adjusted grab the helmet and twist - the skin on your forehead should move with the helmet.

Very comfortable and good quality.

Very pleased with this helmet, it has a good solid feel without being too heavy. The inner lining is very soft and comfortable as is the nicely padded chin strap. It was easy to fine tune to fit using the size adjustment button at the back of the helmet and the adjustable chin straps. I feel the helmet is good value for money.
