Stable Traction on Snow and Ice

The Petzl Irvis Crampon is designed to provide dependable traction when traveling across firm and challenging mountain surfaces. Its 10-point layout maximizes stability while walking on hard snow and provides effective grip when moving over ice.

The two wide front points are particularly useful for gaining purchase in snow, helping provide confidence during glacier travel and classic mountaineering routes.

Durable and Lightweight Construction

Despite its robust construction, the IRVIS is designed to remain relatively lightweight and compact. It weighs up to 790 g with the ANTISNOW system, helping reduce the overall equipment load during long approaches and ski tours.

The use of steel, stainless steel, aluminum, and nylon provides a combination of durability, functionality, and weight efficiency suitable for demanding alpine use.

ANTISNOW System

Snow buildup underneath crampons can reduce traction and make movement less efficient. The integrated ANTISNOW system helps limit snow accumulation across a variety of snow conditions, supporting more consistent crampon performance during mountain travel.

• LEVERLOCK UNIVERSEL: Designed for footwear with heel welts.

The crampon is also compatible with different toe bails, allowing it to fit a broad range of footwear, including stiff boots, flexible boots, telemark boots, and snowboard boots.

ALPEN ADAPT Modular System
