How to Measure and Check the Fit
| Category | Instructions |
|---|---|
| Helmet Head Circumference | Wrap the tape around the head about 2.5 cm above the eyebrows and ears. |
| Helmet Fit | The helmet sits level, about one to two fingers above the eyebrows. It should not shift when shaking the head. |
| Check Helmet with Goggles | The goggle should meet the helmet without a gap and should not press down on the nose. |
| Measuring Sunglasses | Use a well-fitting pair as reference and compare lens width, bridge distance and temple length. |
| Goggle Size | Julbo recommends choosing goggle size according to helmet size. |
Not every Julbo model is available in every size. For sunglasses and goggles, curvature, lens dimensions, frame width and helmet compatibility can affect the actual fit.
