The Black Diamond Helio 350 is a downhill-oriented, freeride-style alpine touring binding that comes in a lightweight package. The Helio 350 includes a slew of design features that tailor the binding towards fast and demanding skiing, but still weighing in at a reasonable 350 grams. This binding is ideal for anyone that values safe and dynamic tech bindings.

The binding is manufactured entirely from aluminum alloy and stainless steel, creating a remarkably durable product that will hold up to years of use/abuse. The Helio 350 toe piece features a wide mount pattern for better power transmission, an integrated crampon receptor, and 2-spring tech toe. The heel unit features FIVE magnetic riser height positions, an integrated ski brake, elastic travel to maintain a constant release value, and 30 mm of binding adjustment. There is a lot going on here for such a compact and svelte piece of equipment.

The Helio 350 is a fully-featured alpine touring binding that is built to last. It's for freeride charging, safety-conscious touring, or backcountry skiing that doesn't skimp on binding functionality. Next time you are wanting a bombproof binding that can handle just about any level of downhill skiing, look to the Helio 350.

The bindings are good quality but they froze and were very difficult to turn when time to ski down

Great bindings not sure about the Atomic boots

The bindings are great but the boots are giving a bit of trouble. The arches of my feet hurt a lot! Anything you can do to help?
