Our Guides Love the Mutant
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 colors, 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.

Guide Pick
, RMI Expeditions Guide
How Guide Pick™ Works
The guides over at RMI collectively spend over 10,000+ days a year on the world's highest mountains, climbing hundreds of thousands of vertical feet. They put their gear and apparel through the wringer. This stuff is their work wear and they simply will not tolerate inferior gear.
At the end of the climbing season, guides are given a survey to find out what gear they are using and why it is their favorite. We don’t often get complete agreement but we do get alignment and by looking at the data, a few clear winners rise to the top in each category.
We take those winners, and stamp them with the Guide Pick™ logo on our site. We also compile this wonderful little document, which you can use to see top contenders, gear advice, Guide Quotes, and more.
