Marker 4.5 Junior Ski Bindings — Right-Sized Safety, Lightweight Confidence

Kids deserve gear that’s built for them. The Marker 4.5 delivers real-deal release performance in a light, easy-to-use package—so new and growing skiers can build skills with less worry. A smart 4-Linkage Biotech toe manages tricky backward-twisting falls, while a smooth AFD gliding plate helps ensure clean, consistent releases. Add the Compact Junior heel and a balanced stand height, and you’ve got a trustworthy first binding for frontside laps all season.

Why you’ll love it
