  • Destroys Ecosystems

    Between 4.8 and 12.7 million tonnes of plastic pieces are dumped into our oceans yearly. That is one garbage truck of plastic is discarded into our oceans every minute. So, hundreds of millions of marine animals are killed.

  • Spreading Toxins

    Plastic sticks can take up to 500 years to decompose, threatening wildlife and spreading toxins. An estimated 35% of microplastics in aquatic systems come from washing synthetic clothes.

  • Greenhouse Gases

    Plastic production is an extreme polluter of the environment. Throughout their lifecycle, plastics have a significant carbon footprint and emit 3.4% of global greenhouse gas emissions.

  • Increase Risk Of Cancer

    Research suggests that all plastics may leach chemicals when interacted with and especially when heated up, even slightly. These chemicals, such as bisphenol A (BPA), increase the risk of cancer in humans.

  • Hormone Disruption

    There is a growing body of evidence that microplastics can mimic and interfere with the production of sex hormones, for example, estrogen and testosterone. Simply put, microplastics are endocrine disrupters, altering our hormones.

  • Decreased Fertility

    Studies have revealed that micro-plastic exposure leads to testicular toxicology and reduced sperm production. In addition, in another study, fertility in female mice is reduced under micro-plastic exposure.

  • Weakend Immune System

    Some microplastics impede the immune response by disrupting the extracellular matrix and signaling transduction. In simpler terms, microplastics alter your immune system by disrupting its function.

    "They [plastics] lower testosterone and so have the strongest influences on the male side, for example diminishing sperm count, though they are bad for women, too, shown to decrease libido and increase risk of early puberty, premature ovarian failure, miscarriage, and premature birth."

    "There is more than you think (...) most of the clothes we wear these days are made from polyester, nylon, and elastane. These plastic materials, even stuff that doesn't necessarily feel like plastic, you got to check every label."

  • Dr. Anthony G. Jay

    CEO of AJ Consulting & Author of Estrogeneration

    “Even while human testosterone has been diminishing for thousands of years, testosterone has seen an especially dramatic dropout in recent history. A truly massive drop. All about the time estrogenics have been rising, 'coincidentally'.”

Yes, unfortunately, plastics are detrimental for our health. Studies have found that plastics disrupt the our immune system, fertility, hormones, and increase the risk of cancer.

What material is the shirt made of?

The shirt is made of 100% bamboo fabric, which means that it is 100% organic. In addition, the shirt is OEKOTEX certified. This label certifies that every product component, from the fabric to the thread and accessories, has been rigorously tested against a list of up to 350 toxic chemicals.

The shipping price depends on where the shirt is being shipped and is calculated at check out.

When can I expect my shirt to arrive?

How do I know my size?

The last product image is a sizing chart you can use for reference.

For ladies, we recommend getting a size smaller than what you usually wear.

Please keep in mind that because the shirt is made of an organic fabric, it will shrink slightly right after washing and then expand to almost it's original, out of the box, size.

How do you wash this fabric?

Bamboo is not a fabric that you need to wash very often. Ironing isn't necessary either.

However, when the time comes, please keep in mind the following:

1) Do not exceed over 30°C

2) Wash it inside out

3) Do not tumble dry

Our favourite way to wash it is by hand as it helps us disconnect a bit and just enjoy the moment.
