One leading the way, I personally am fully convinced of the mask. The baptism of fire of a 2h crossing at about 5 ° C outside temperature with a mix of house and outdoors. The mask is not even started in the viewing area ... top. Shortcoming of the mask is the "ill-considered" padding in the nose area. Here the nostrils are concentrated and thus impair respiration. Who is ever gehechtet with adrenaline through a rough terrain, knows how important then is a free breathing. The problem was corrected by me by cutter by about 1cm padding was removed on both sides around the nose. Apart from the "behebaren" Manko, a clear recommendation for this price.
