A lot of youth goggles and helmets on the market today are designed to create and effective weather seal when used together.  Companies like Giro, Oakley and Smith are starting to design helmets and goggles together as part of an integrated system. Gaps between the goggles and helmet are minimized this way and fight fogging that can occur from condensation within the goggle. Corresponding ventilation channels carry a steady stream of air through these vital pieces of equipment, which also fights goggle fogging and keeps the helmet cool and dry as well. Other features also include silicone on the interior of the goggle straps to minimize slipping, and articulated outriggers connecting the strap to the goggle frame for a precise fit at all angles.
