One-touch Lock single dial tightening system
One-Touch Lock System
Multi-buckle boots ask you to adjust four different zones and hope they add up to an even fit. One-Touch Lock skips that guesswork entirely — a single dial drives the entire closure system at once, locking in the whole boot with one motion, and releasing it just as fast.
Less time fighting your gear. More time on it
Ezion Step-in Snowboard Bindings
Traditional strap-in snowboard boots trade speed for structure — you either get quick entry or you get support, rarely both. SUN's Ezion hard-shell binding architecture closes that gap: step in, and the shell locks around a soft boot with the precision of a race binding.
One step to lock in. One pull to release. Under a second, every time — without giving up the control a rider actually needs on the mountain.
Wing Opening System / "SOS" rescue release system
Wing System: The shell swings open wide for effortless entry, then wraps into a snug 3D fit the moment it's tightened — no fighting to get your foot in, no compromise on hold once you're locked.
"SOS" rescue release systemCut to open, ensuring no harm or danger during rescue, allowing for quick release, adding an extra layer of safety to every skiing experience.
Independent Walkable Liner
Take the boot off the mountain and it shouldn't fight you. SUN's walkable liner stands on its own — built to walk, not just to wait inside a shell. Across the parking lot, through the lodge, behind the wheel on the drive home — it moves like a real boot, because it is one.
The perfect combination of performance and comfort
