Pros & Cons

Reasons to buy:

User Reviews

• Easy to adjust length.
• One of the lightest steel crampons on the market.
• Easy to pack.

Expert Reviews

• Nice adaptability between automatic and semi-automatic, depending on which boots I’m using.
• A good balance between durability and lightweight.
• Not as light as aluminum crampons but more versatile since they can be used on rock.
• A good one-crampon quiver for ski mountaineering and glacier travel.

Reasons NOT to buy:

User Reviews

• Doesn’t fit large shoe sizes.

Expert Reviews

• Can be tricky to switch the front from a toe bail (automatic) to a strap (semi-automatic).
• Toe bail may not fit narrow boots as well.

Summary:

The Petzl Irvis 10-Point Crampon is impressively lightweight for a steel crampon. As a result, it is durable yet not too burdensome to bring on trips. Unfortunately, those with large feet may not be able to fit their longer boots into this crampon.
