THE PEOPLE BEHIND GREEN SHIRTS
The Team
Get to know the people who move GREEN SHIRTS every day – behind the scenes and on the front lines. Diverse backgrounds, one common goal: timeless design and clear information about materials and origin.
Niklas Astor
Founder & Executive
Shocked by the true face of the clothing industry, Niklas decided to take matters into his own hands and, after graduating from high school, founded the label "GREEN SHIRTS" in 2012. He struggled for a long time as a "one-man company" until he assembled a team around him in 2013. His vision: an ecological and social approach to the clothing industry. Along the way, he successfully completed the "Pioneers of Change 2013" course for empowering pioneers of change and studied business management.
Joshua of Gabain
COO & Executive
Degree in Economics, Business Angel, and active in the business world for years with a focus on "sustainable development." But that’s not all. Programming and making music are also part of this versatile all-rounder's repertoire. "Curious and a workaholic" is how the other team members would describe him, as he is always working on four projects at once and rarely rests. Whether it’s start-ups, secret projects, investment-ready programs, or established companies, Josh is involved everywhere. And he contributes even more than just his work at GREEN SHIRTS. We are very happy to have such vast experience by our side in our young company.
Ella Hartweger
Sales & Key Accounts
After many years of experience at durchblicker, Ella has become an integral part of our sales team. Partly raised in Barcelona and with experience in the textile industry, she helps achieve the best possible results for our customers. Versatile and quick-witted, she provides tailored, customer-focused support to our major accounts. With her friendly approach, she has made every customer happy.
Christopher Ritsch
Sales & Key Accounts
Christopher is a true bundle of energy and a true team player. In addition to his communicative nature and positive charisma, he's a true Excel whiz. With experience in his own startups and management consulting, he's the first point of contact for major clients at the highest level.
Paul Böse
Finance & Controlling
Paul is our numbers guy with a heart, and that's truly meant in every sense of the word. With a commercial apprenticeship, a dual study program in tax law, and two years of professional experience as an accountant, he brings solid financial expertise to the table. His current agricultural science studies at BOKU demonstrate that he doesn't just manage sustainability; he lives it. Anyone who works with Paul quickly realizes: this is someone who not only excels at his job but also genuinely enjoys it.

Production
Fairly manufactured in Germany, Europe & Asia – with short supply chains and renewable energy. Our partners are audited, work safely, and pay fairly.
Printing process
Branding without compromise: We refine using environmentally conscious techniques, tailored to the motif, durability, and feel.
Materials
Timeless fabrics with a future: organic cotton, linen & hemp, TENCEL™ Lyocell, and recycled fibers. We select materials based on impact rather than trends – skin-friendly, robust, renewable.
Certificates
Verifiable instead of nice-to-have: We work with recognized standards and display them transparently for each product.
YOUR BRAND. OUR MATERIALS. FAIRLY PRODUCED.
For questions regarding teamwear, merch, or your own collection, we are happy to assist you personally.
For over 10 years, we have been supporting companies, teams, and creators in the production of high-quality, sustainable textiles – sourced from Germany and Europe, and produced fairly. Whether it's a small run or a premium collection: at GREEN SHIRTS, you get both from a single source.
