Collider Cap Sizing

Level Six headwear sizing diagram: two side-view line drawings on a white background. On the left the Quartz Hood, marked tight fit, with its rear zip; on the right the Collider Cap with its vented ear panel and chin strap. A red tape line runs around each one at the head circumference, above the ears and across the middle of the forehead.
How to measure
  • Head circumference: run the tape around your head at its widest point, roughly a finger’s width above your eyebrows and just above your ears, keeping it level all the way round.

Find your size

Fill in every box in centimetres / inches and we will suggest a size.

All measurements in centimetres / inches. The centimetre figures are the range each size fits; the inch figures are printed as a single number per size, which is the top of that range. The Quartz Hood is cut for a tight fit, so if you are between sizes on the hood, size up.
