What We Do

Sell eco-friendly apparel, help individuals understand their unique carbon footprint, and plant a tree for every item sold.

Our Mission

Bring awareness to the best sustainable solutions currently available and innovate new ones wherever necessary.


As industry experts in sustainability, we put factual numbers to your impact so you can see the clear-cut difference you are making in the world.

Our Mantra

Save Money,

Save the Planet,

Help People in Need.

Why Sustainability?

Pollution is increasing. Waste is piling up. Our climate is warming. Weather is more extreme. Animals are going extinct. The list goes on.

Times are changing and we need to change with them.

Eco-Responsible Apparel

We provide an environmentally sustainable solution to the traditional negative practices of the apparel industry with our eco-responsible manufacturing.

6 to 8 recycled plastic bottles go into each of our luxuriously soft tri-blend t-shirts.

Tree Planting

Every 2 seconds man destroys an area of forest the size of a football field and 80% of our world's forests are already destroyed.

We partnered with One Tree Planted to restore our world's forests and absorb carbon emissions from the atmosphere.

Gage Mruz

Founder & CEO, Greenstain

Hello everyone! My name is Gage Mruz, a 22-year-old with a Bachelor of Science degree in Environmental Studies from the University of Nebraska-Lincoln and the Founder of Greenstain. My life's purpose as a young entrepreneur has always been to leave the world in a better place than I found it.


Given my natural love for problem-solving, it's no surprise that I gravitated towards one of the most complex problems of our time with increasing amounts of carbon in our atmosphere, wide-spread pollution, and a planet that needs help.
