    Product Description
    Whether mountaineering in demanding alpine conditions or spending long days conquering multi-pitch ascents, the Mutant 38 is fine-tuned for vertical ice and steep terrain. Developed with the help of local guides and athletes and honed over years of abuse in extreme conditions, its close-to-body fit and refined feature-set promotes safety and stability in even the worst of conditions. New colours, advanced fabrics and refined features make the latest iteration of Mutant 38 even more formidable than its predecessor, proving that the evolution isn't done yet. The whole Mutant family benefits from the addition of lightweight, recycled NanoFly and robic fabrics for impressive durability and lower environmental impact than virgin materials.
