The goggles are the other half of your helmet. There are brands which design the helmets and their corresponding goggles, just like Fox and 100% do. But normally you can combine one with another as long as they fit well to you and your helmet too. Also, there are brands with infinite experience in the sports goggles field, such as Oakley, that create universal frames.
If you're going on sand because you're off to the dessert or the dunes or you like the motocross circuits in the style of Valkenswaard or Lommel, you'll need goggles specific for sand. Off-road goggles are also used in supermoto, combined with a motocross helmet, as they are also the best protection against dust and dirt on a mixed track.
And if you use eyeglasses, maybe you'll be interested in some goggles prepared for this, with a greater interior space in order to accommodate graduated lenses.
And if you already know which you want, just choose a colour and off you go! We have them all, from white to black, passing through orange for KTM fans or fuchsia for her .
