Cumulus – Ultralight Down Sleeping Bags and Apparel from Poland
Polish goose down, honed by the country’s harsh winters, boasts some of the highest fill powers in the world, making it ideal for ultralight gear! As part of inspiring European consumers to buy local for a sustainable Europe, we’re spotlighting brands like Cumulus that champion quality craftsmanship right here on the continent.

Introduction to Cumulus
Cumulus Equipment hails from Gdynia, a vibrant port city in northern Poland, where it was founded in 1989 by avid outdoorsman Zdzisław Wylężek. Amid Poland’s transition to a free market, the company began in a modest basement, focusing on innovative down-filled products. Today, with over 30 years of expertise, all manufacturing remains in-house at their Gdynia facility, ensuring 100% European production. This local approach allows for meticulous quality control, ethical sourcing of Polish goose down, and customisation to meet adventurers’ needs. By keeping operations within Europe, Cumulus supports regional economies and minimises transport emissions, aligning with sustainable practices.

A Short Story of Inspiration
In the late 1980s, as Poland emerged from decades of restrictions, Zdzisław Wylężek saw an opportunity to blend his passion for hiking and cycling with entrepreneurial spirit. Starting small, he crafted gear that embodied his “fast and light” ethos, using locally sourced down that outperformed imports. His son Jacek, now deputy CEO, recalls the hands-on beginnings: “I believe that a continuous evolution of our products, which comes from direct feedback from our customers, differentiates us from others.” Under Jacek’s leadership, Cumulus has grown to a team of 50, fostering a family-like atmosphere with company trips to the Tatra Mountains and beyond. This commitment to innovation and community has turned Cumulus into a beacon for ultralight enthusiasts, proving that European ingenuity can conquer global challenges. Their story inspires a new generation to embrace durable, eco-conscious outdoor pursuits, building resilience one stitch at a time.
