Tear offs are shaped transparent films used to protect the visor from any blows from debris raised by karts racing in front of you. They also allow drivers to have an optimal view in all conditions: dirt is in fact deposited on this film, instead of directly on the visor. Drivers can then remove them with a simple tear even while they are driving so that the visor is clean again. Arai sells this product, for each of its models, in packs of 5 tear offs each. So make sure you buy the tear offs that are specific to your helmet model.
