Union Atlas Pro Step On Snowboard Bindings 26/27

The 26/27 Atlas Pro Step On from Union is a stiff all-mountain snowboard binding built for riders already committed to Burton Step On boots. Its published flex is 8/10, putting it above the standard Atlas Step On when quicker edge input matters more than a forgiving chassis.

A forged-carbon beam reinforces the hybrid highback, while the rear Drive Frame adds Hi-Flex EVA behind the platform. Union uses those parts to support its stiffness and power story; the Duraflex CB baseplate carries that input into the board. This build is meant for riders who actively drive a binding, not beginners looking for an easy, soft feel.

The boot interface is the first decision. Burton Step On compatible boots click directly into the heel and toe connection points, with no conventional buckles to close. Standard snowboard boots have nowhere to engage, so they will not work. The convenience also removes separate ankle-strap and toe-strap tension adjustment. Choose the regular two-strap Atlas Pro if boot freedom and pressure tuning beat entry speed; choose the softer Atlas Step On if the same ecosystem appeals but flex 8 sounds excessive.

Two mounting disks come with the binding: one serves standard 4x2 inserts and the other serves Burton's Channel. A 4x4-only deck or an older Burton 3D layout falls outside Union's stated fit. Available binding sizes are S, M, L and XL, selected from the compatible boot rather than rider weight. Because the catalog does not provide the boot range behind each letter, bring us the exact Step On boot; we will verify the match, install the binding and set the stance.
