The Union Atlas is the new and improved big brother of the Union Force binding. A few of the new things you will see on this binding are a multizone highback for extreme comfort, lightweight, and response, an all new extruded anodized aluminum heelcup that adds 30% more strength, stage 3 dupont base plate for more performance to weight ration and a lifetime warranty, and all new direct connect system that offers a 3D multi-layer tapered strap that distributes pressure evenly.
