Our Journey to the Ultimate Waterproof Jacket
By Nirmal Purja – NIMSDAI
From my early days as a courier navigating unpredictable weather to my career in the UK Special Forces, I have operated in some of the world's most extreme environments. After leaving the British military following 16 years of service, I went on to climb all 14 eight-thousanders—both with and without supplemental oxygen—including the highest peaks on all seven continents. Throughout these experiences, I often found myself imagining the perfect waterproof jacket.
The frustration grew as I kept purchasing multiple jackets for different activities. For example, you need next-level waterproofing to survive sideways rain in the UK, a completely different jacket for skiing, and yet another for high-altitude mountaineering—one that is lightweight, has large pockets, decent zip pullers, RECCO technology, and so on. Each time I invested in another product, I faced the reality of limited funds and the overwhelming clutter of gear. It became clear that not only was this approach unsustainable for my wallet, but it was also an unnecessary strain on the environment.
This led me to an idea: why not create a single product that could adapt to every situation? And so, our waterproof jacket was born—a solution crafted from firsthand experience and a deep understanding of the diverse needs of adventurers like myself.
Our waterproof jackets are not just another piece of gear; they are the result of years of meticulous planning and cutting-edge technology. Every feature has been carefully designed for functionality, durability, and performance. From advanced materials to breathable designs, we have integrated everything you need for any environment into one versatile jacket. We are not claiming to be the best just for the sake of marketing like everyone else. The reality is, there is no one else in the world who lives and breathes the 8,000m peaks and Seven Summits like we do, while also having a deep passion for creating something truly meaningful.
This is more than just a jacket; it is a commitment to safety, sustainability, performance, and your adventurous spirit. With our waterproof jacket, you’ll be prepared for anything—whether you're climbing mountains, skiing down slopes, or tackling the everyday challenges of life.
Welcome to the future of outdoor gear—where function meets style, and every adventure is just a jacket away. Experience the difference and embrace the freedom of having one reliable companion for all your waterproof needs.
