Compostable tear offs accessories for the #A Celona riding glasses. But why has no one thought of installing tear-offs on cycling glasses? Well, number A did it on the Celona model and whether it's during an XC World Cup, a Paris-Roubais or a very wet Gravel event, it's as if you were riding with several pairs of glasses clean... so much more pleasure, comfort and safety. Our tear-offs are made of compostable material. That doesn't mean they should be thrown out, but if that happens, they'll decompose in about 6 months. Note that our material is very slightly less transparent than the petrochemical equivalent; we therefore recommend 1 to 2 layers of tear-off films for perfect vision. Note: tear off only adaptable on Celona with transparent screen (equipped with fixing pins) 10 pieces per pack.
