KNOWLEDGE FROM STORMS:
An Expert’s Guide to Surviving the World’s Toughest Environments
by John Barklow
St. Martin’s Press, April 2027

John Barklow has dedicated his career to teaching special operations forces and rescue groups how to survive in the world’s toughest environments. Drawing on his twenty-six years of military service and fifteen years spent developing advanced apparel systems for military and hunting applications, Barklow understands that survival depends on proper training. His approach is straightforward: teach not just what works but why it works so people can adapt when conditions change. He’s transformed complex survival skills into practical, real-world knowledge that works when it matters most. Instead of teaching single solutions, he helps people understand the principles behind survival skills, enabling them to make smart decisions in unpredictable situations.

KNOWLEDGE FROM STORMS is the culmination of those lessons, written as part adventure story and part instruction manual. The book weaves together the deep information one needs to thrive and survive in austere wilderness and pursue their dreams outdoors, whether that be mountain climbing, backcountry hunting or just surviving in extreme conditions. The book comprises twenty-eight chapters that look at planning, training, equipment and survival.

“If there was one human being that I had to pick to help me survive a life-or-death emergency situation in the wilderness, without a shadow of a doubt, my choice would be John Barklow. From his extensive experience in real-world situations to his design, testing, and implementation of the most advanced outdoor gear in the world, he’s an incredibly valuable resource of information, and I can’t recommend his book enough.” —Joe Rogan
