Helmet size & fit

Blackbird Jet Helmet – Matt Black

Measure your head circumference to choose your size.

These are head-circumference measurements from Merlin’s helmet chart. Merlin describes these helmets as an intermediate oval fit. Use the chart as a starting point and check the fit before riding.

Head shape: Intermediate oval

Slightly longer from front to back than from side to side. Head circumference and head shape both matter when choosing your fit.

Head-shape information: Merlin (manufacturer).

How to measure your head

Following Merlin’s guidance, wrap a soft tape around the circumference of your head from the middle of your forehead, above your eyebrows. Pass the tape over your temples and keep it level around the widest part of your head. Include that measurement and your selected size when asking PCM for fit help.
