It is narrow-cut and not suitable for large heads: despite elastic material is very stiff and always slips to where you do not want them. In particular, the nose rider nostrils pressed flat and wanders in my (from chin to crown) long head above the nostrils down. In addition, the mask leaves the breathing air under the eyes climb, resulting in constantly fogged glasses. The fit does not allow me but also to push the eye opening or the nose to rider under the nostrils.
With the Nalini Pro Alpinia I got along better.
