Pros & Cons

Reasons to buy:

User Reviews

• Toes are incredibly easy to step into.
• Skis really well due to the forward pressure in the heel piece.
• Risers are easy to flip.
• Bought the Ion 10’s for my wife since I liked the 12’s so much.
• Even though I know it’s not important, they look cool.
• Much easier to step into than Dynafits.
• The toe piece doesn’t ice up.
• A good balance of weight and performance. Not the lightest and not the highest performing, but a good mix.

Expert Reviews

• The brake can have icing issues.
• The heel riser can flip back over unintentionally.
• Very user-friendly.

Summary:

The G3 Ion 10 & 12 Binding is a mid-weight tech binding that has a robust and reliable feature set. It’s biggest strength is the ease with which the toe piece can be stepped into. The Ion strikes a very nice balance between weight and performance.
