The Giro Rev is a standard for little skiers and an excellent goggle. A Microfleece Facing feels soft to the skin and feels very comfortable for little skiers and snowboarders who may not be used to something on their face. Dual Layer Face Foam keeps the wind, snow and water off their face. The Rev has an Anti-Fog Coating that will keep the lenses clear, even in difficult conditions. Fitting the Rev with a helmet is very simple since it has a seamless compatibility with all Giro youth helmets Youth Medium Frame, Cylindrical Thermoformed Lens, Double Layer Face Foam w/Microfleece Facing, Anti-Fog Coating, Seamless Compatibility w/Giro Youth Helmets, Race: No, OTG: No, Special Feature: None, Helmet Compatible: Yes, Goggle Ventilation: High, Goggle Lens Change: Permanent, Frame Size: Medium, Lens Shape: Flat, Lens Type: Mirrored, Model Year: 2021, Product ID: 590143, Model Number: 7105431, GTIN: 0768686228728, Spare Lens Included: No, Category: Kids
