ESG REPORT 2024/25

CUMULUS®

We are a manufacturer and we know that making gear always leaves a footprint. That is why this report is not a story about having everything figured out. It is a record of the choices we make along the way: how we design lighter and longer-lasting gear, why we keep production in Poland, how we repair products from previous decades, and how we support the places we want to return to.

WHY WE PUBLISH THIS REPORT?

The 2024/25 report focuses on what has changed over the past two years: materials, hardshells, repairs, partnerships and emissions data. It also shows where the work is not finished yet. Because transparency means more than reporting progress. It means being honest about the questions that remain open.

Products

Lightness, durability and repairability remain the core of how we design gear.

People

Behind every product are people who sew, inspect, repair, pack and support customers.

Planet


We reduce emissions, support wetlands and fund long-term nature conservation.

In 2024 and 2025, we repaired 1,360 Cumulus® products. Some of them were sleeping bags made in the 1990s. For us, repair is not an add-on. It is part of the product lifecycle. It can extend the life of gear, reduce the need to buy new equipment and keep trusted products on the trail for years.

Materials that matter

What we learned from working with Pertex®, Toray, GRS-certified fabrics, bluesign® standards, PFC-free solutions and the first step toward mono-material design.

Gear without an expiry date

How repairs, Lifetime Experience and products from previous decades help extend the life of outdoor gear.

Four years, one direction

How total CO₂e emissions fell from 423 tonnes in 2021 to 125 tonnes in 2025, and why product durability is also part of our climate strategy.
