Atomic Four JR Junior Ski + Snowboard Helmet Graphic/Glacier
The Atomic Four JR is a lightweight junior ski and snowboard helmet that combines dependable impact protection with a comfortable, easily adjustable fit.
Its In-Mold Shell bonds an impact-absorbing EPS foam core directly to a lightweight polycarbonate outer shell. Atomic Holo Core adds an extended crumple zone designed to absorb impacts and provide up to 30% greater impact protection than industry standards require, while Aircon Venting channels warm air away from the head.
The height-adjustable 360° Fit System uses a rear dial to fine-tune the fit around the whole head. A removable and washable Full Cap Liner with integrated 3D-moulded ear pads provides adaptable comfort, while the Ear Fit System, audio-compatible ear pads and removable goggle clip add practical versatility.
