How to Measure and Check the Fit

Category	Instructions
Helmet Head Circumference	Wrap the tape horizontally around the widest part of the head, approximately 1–2 cm above the eyebrows and just above the ears.
Helmet Fit	The helmet should fit firmly and evenly. When the helmet moves, the scalp should move with it.
Between Sizes	For Trajecta and Status, 100% recommends choosing the larger size when the measurement is on a size boundary.
Moto / MTB Goggle	The face foam should seal evenly. There should be no uncomfortable gap between the helmet and goggle.
Sport Sunglasses	The temples and nose bridge should sit securely without pressure points. Choose SL, XS or Youth models for smaller faces.
Snow Goggle	Regular Fit suits standard nose bridges; Low Bridge Fit suits lower nose bridges and reduces pressure around the nose.

The current size selection and product-specific size chart for the individual 100% model always take priority.
