The Mammut Crag Sender Climbing Helmet is a high-performance piece of safety equipment designed for climbers who prioritize both weight and protection. This dual-sport helmet features a robust hard shell construction combined with an internal EPS foam core, reinforced with Kevlar in critical areas to ensure structural integrity while maintaining an exceptionally low weight. Its specialized shape provides extensive head coverage, offering a low-profile fit that does not compromise on safety during demanding climbing and mountaineering activities.

Advantages

The primary benefit of this helmet is its advanced material composition, which balances extreme lightness with high-impact protection. The inclusion of Kevlar reinforcements in key zones enhances the helmet's durability without adding unnecessary bulk. Furthermore, the design incorporates a highly ventilated structure that promotes airflow, keeping the wearer comfortable during intense physical exertion. The low-profile design ensures that the helmet remains stable and unobtrusive, while the comprehensive head coverage offers peace of mind in varied climbing environments.

• Alpine climbing

When it may not be suitable

This helmet is specifically engineered for climbing and mountaineering activities. It is not designed for use in high-speed sports such as cycling, motorcycling, or winter sports like skiing, where different impact standards and ventilation requirements apply.

Key specifications

• Construction: Hard shell with EPS foam core
• Reinforcement: Kevlar inserts
• Fit system: Snap buckle
• Design: Low profile with extended head coverage
• Ventilation: Integrated airflow channels

How to use

To use the helmet, place it on your head so that it sits level and covers the forehead. Adjust the internal fit system using the snap buckle mechanism until the helmet feels secure but comfortable. Ensure the chin strap is fastened correctly and adjusted so that it sits snugly against the skin without restricting breathing or movement. Before starting your climb, perform a quick check to ensure the helmet does not shift significantly when you move your head.

What to consider before purchase

• Ensure the helmet size corresponds to your head circumference for optimal safety.
• Check that the helmet is compatible with your preferred headlamp model if you plan on night climbing.
• Verify that the helmet has not sustained any prior impacts, as structural integrity can be compromised after a significant blow.

Usage recommendations

Regularly inspect the shell and internal foam for cracks or signs of wear. Store the helmet in a cool, dry place away from direct sunlight and avoid placing heavy objects on top of it to prevent deformation.
