One tree planted for every garment.

Trees help us fight climate change by absorbing carbon dioxide from the atmosphere that causes global warming. That's why we plant one tree for every garment to neutralize our carbon footprint.

Materials 101

Sustainable from yarn to you.

To make the perfect basic, we started by getting the fundamentals right: we use the best fabric made from the highest quality raw materials. Our garments are engineered to last and stay soft with an innovative blend of Supima cotton and Tencel. Fabrics are researched, selected and designed for comfort, quality, and everyday performance using sustainable and eco-friendly practices.

Supima Cotton + Better Cotton Initiative

We use American-grown, sustainably sourced Supima cotton. Supima is the world’s finest cotton because of the extra-long staple fiber that gives it premium properties: strength, softness, pilling resistance and color retention. All cotton used in Proto101’s garments is grown to meet the standards of Better Cotton Initiative to reduce our impact to the environment using less water and fewer pesticides.

TENCEL Lyocell

Our t-shirts are blended with TENCEL, known for its natural moisture wicking properties, comfort, and durability. TENCEL is sustainably produced from renewable wood materials without use of pesticides or insecticides.

Oeko-Tex Standard 100

Oeko-Tex is a global third party standard on testing textiles for harmful substances. Our fabric has been tested and certified to be free from harmful levels of more than 100 toxins and chemicals.

Recycled Packaging

Proto101 ships our products in a compostable, biodegradable package that is made of 100% recycled materials. The plastic bag protecting each piece is also made of 100% recycled plastic.
