This T-shirt is beautifully soft:

  • It is made from 100% natural organic cotton. No dyes. No bleach. 
  • You will love how this shirt feels next to your skin!

It is 100% made in the U.S.A. It is 100% sustainable.

  • The cotton was grown on a family farm in Texas that has been certified organic for over 25 years
  • The T-shirt was sewn in South Carolina with high-quality double-needle stitching

By buying this shirt you are supporting American jobs, farms and communities, and helping to save the planet from global warming. It is the most environmentally-friendly, eco-conscious and sustainable T-shirt you can buy.

It has a lifetime carbon footprint of zero:

  • U.S.A.-grown organic cotton has the lowest carbon footprint of all the major fibers (cotton, hemp and polyester) used for making shirts.  Its carbon footprint is 61% lower than conventionally grown cotton, 35% lower than imported organic cotton and 76% lower than polyester1. This makes it the most environmentally conscious article of clothing we know of!
  • However, even U.S.A.-grown organic cotton still generates a small carbon footprint. This carbon footprint is offset completely by Zero Carbon®LLC by purchasing verified, incremental carbon offsets2. Making it even more eco-friendly!
  • The total lifetime carbon footprint of a T-shirt is about twice that of making it. This extra carbon footprint is caused by washing and drying the shirt over its lifetime3. This entire lifetime carbon footprint is completely offset by the carbon offsets purchased by Zero Carbon®LLC. This makes this T-shirt completely sustainable!
  • So you can feel great about buying this T-shirt because it has a zero carbon footprint over its entire lifetime! We believe it is the world’s first T-shirt with a lifetime carbon footprint of zero.

We keep our costs, and carbon footprint, low!

  • Transport costs are minimized by buying directly from family farms right here in the U.S.A. Nothing is made in China. And…
  • We do not pay expensive models to wear our shirts

So this beautifully soft, organic cotton, zero carbon, made-in-the-U.S.A. T-shirt costs only $19.99.

Only available in the U.S.A. because shipping it overseas would create a huge carbon footprint.

2. These carbon offsets fund a project to capture methane gas that would otherwise leak into the atmosphere from exposed coal seams on the Southern Ute Indian reservations in Utah. Even the carbon offsets support American jobs and communities! Methane gas is 25 times stronger than carbon dioxide in causing global warming. These carbon offsets are audited and verified to be real and incremental by Cool Effects™.  Verified incremental means that the carbon offset would not have happened without this program. This is in contrast to many carbon offsets that rely on planting trees in rainforests to capture carbon dioxide out of the atmosphere. Reforestation programs are often not truly incremental because trees naturally seed and regrow, especially in a rainforest. So planting trees does not necessarily result in capturing more carbon dioxide from the atmosphere than would happen naturally. The Southern Ute Indian methane capture project is 100% incremental because if the Tribe did not capture the methane it would leak into the atmosphere and cause global warming.
