Product Description
Built for riders who refuse to pick a lane, the Mercury FASE Borealis pairs the locked-in precision of a traditional two-strap binding with Jones's FASE Fast Entry System for instant strap-in speed. The asymmetric Fusion XR Baseplate and AsymFlex Highback deliver crisp response across groomers, technical terrain, and park hits alike. Equally at home charging steep lines or hitting creative features, this binding is the all-resort quiver-killer for confident, well-rounded riders.
Product Details
| Baseplate | Fusion XR Baseplate: asymmetric, low-profile construction in a glass-nylon composite for instant all-mountain response. The Fusion Pad uses a three-layer TPU and EVA blend for dynamic impact protection and vibration absorption across any terrain. |
| Footbed | ImpactCush Footbed: designed for all-day comfort, absorbs board chatter on rough terrain and dampens heavy landings. The sliding footbed integrates with the FASE System and features a 3° cant for enhanced turn response. |
| Highback | AsymFlex Highback: mid-stiff asymmetric outline with an extended upper wing for enhanced turn performance. The softer internal side allows tweak room while the Asym Spine channels more power to the external side. |
| Ankle Strap | DualFlex Ankle Strap: asymmetric design with a stiff TPU core for lightning-fast response and softer TPU edges for all-day comfort and universal boot fit. |
| Toe Strap | Adaptive Fit Toe Strap: flexible exterior outline shapes to the boot, a denser center spine provides a secure lock, and a textured interior surface grips the boot. |
| Toe Buckle | LSR 2.1 Auto-Lock Toe Buckle: Locking Slap Ratchet 2.1 with unique tri-toothed ladder, designed to stay in position for seamless FASE Fast Entry. Updated for 2027 with an improved auto-lock mechanism. |

| Disk | Universal Mounting Disk: compatible with traditional 4x4 inserts, 2x4, and the EST/Channel mounting system. |

Mercury Fase Borealis Snowboard Bindings 2027 FAQ
How do I pick the right binding size?
The Mercury FASE Borealis comes in S, M, and L sizes, each covering a boot size range. On the Mercury FASE Borealis, a Medium fits US sizes 7.5 to 10, so always cross-check your boot against the binding's size chart, not the other way around. Different brands size differently even for the same boot, so measure your boot's middle (MD in millimeters) against the chart to avoid overhang.
Where does the toe strap go?
The toe strap sits over the nose of the boot and pulls your foot back into the heel cup, not flat across the top. On the Mercury FASE Borealis, the Adaptive Fit Toe Strap has a flexible outline that shapes to your boot, a dense spine down the middle for a locked-in feel, and a textured grip surface to prevent slipping, so the boot stays planted once it's strapped in.
What does binding flex change on snow?
Binding flex rating tells you how responsive and forgiving the setup feels. On the Mercury FASE Borealis, the mid-stiff flex (4 out of 5, rated lively) means responsive, direct power transfer without being fatiguing on all-mountain terrain, suited to confident riders pushing harder lines all day while staying nimble in the park.
What is the highback for?
The highback transfers heel-side pressure from your calf into the edge to lock turns. On the Mercury FASE Borealis, the AsymFlex Highback uses an asymmetric design where the softer internal side lets you tweak and press, while the stiffer external spine delivers more power to the heel edge, so you get responsive turning without losing flex freedom for creative riding.
What does canting do?
Canting is a slight inward slope under your foot, built into the footbed to match the natural angle of your legs in a riding stance. On the Mercury FASE Borealis, the ImpactCush Footbed has a 3 degree cant that reduces knee fatigue over a full day of charging, so you stay fresh and connected even on back-to-back runs.
