The Smith Daredevil is a great goggle for your little daredevil on the slopes. A Dual-Slide Strap Adjustment System gives a perfect fit as soon as you adjust the straps. 2-Layer DriWix Face Foam insulates junior skier's faces and wicks moisture if they get sweaty from being out bell-to-bell. The Daredevil is able to accommodate glasses underneath the frame by having a Floating Foam Membrane across the temple area, so your junior will not get any pressure. Smith's Cylindrical Carbonic-X Lens has a wide field of view, and a Fog-X Anti-Fog Inner Lens will keep the lenses fog-free in various weather conditions because juniors do not like to get off of the mountain at all, especially to de-fog goggles.
