Ion Binding

The gear, and the playground. Joe Stock, IFMGA, snapped this on his first day of hundreds testing G3's ION binding and Synapse skis in Alaska's endless backcountry.

Resplendent Descent

30km Deep. Time to Open it up.

We're 30km deep, holed up in a snow cave just 200m from the summit of Mt Resplendent, itching for a ski worthy weather window. I've been on the road chasing storms for six months, it's May, I'm trashed, and all my friends are surfing. Why am I here?

Tested and True

To the Ends of the Earth

From skating rink snow in a pickup truck to summits and steeps in BC, Washington, the Rockies, Patagonia, the Andes, the Arctic, the Alps, Japan, and beyond - the ION left no snow unskied last winter. That was just the beginning.

And Back

To the Equator

The ION didn't just go to the ends of the earth. G3's lead binding designer Cam Shute used field testing as a shameless excuse to bag turns at the centre of the earth, on Ecuador's 5704 m Antisana volcano. Pickup POWDER MAGAZINE'S September 2014 issue, and dig into 'Four Miles High – A misty mountain hop at the centre of the earth' by Andrew Findlay & Steve Ogle.
