You’ve Got Questions, We’ve Got Answers
  • Do organic t-shirts shrink?

    Yes, organic cotton can shrink—but ours won’t dive on you. All tees are pre-shrunk, so no post-wash surprises. Just follow the care instructions and enjoy your premium tee, season after season.

  • How long does organic cotton last?

    If you’ve ever rocked organic cotton, you know the deal—it’s ridiculously soft on your skin. No rashes, no weird chemicals, no drama. And because it skips the chemical cocktail, it lasts season after season (we’re talking 2–5 years of poolside duty).

  • Why does my new organic cotton t-shirt smell? Is that normal?

    Notice a funky smell on your new organic cotton tee? Totally normal. It just depends on how recently the fabric was woven. Most of the time it’s gone long before your shirt lands in your hands, but sometimes it sticks around a little stronger. No worries—it won’t affect durability, and it usually washes out after the first rinse.

  • What is the difference between 100% cotton and organic cotton?

    Plain 100% cotton is just cotton—but it might be grown with pesticides, fertilizers, or GMO seeds. Organic cotton? Totally chemical-free, farmed with sustainable methods that protect the soil, water, and wildlife. It also goes through certifications like GOTS to prove it’s legit. Bonus: chemical-free processing can make it softer, tougher, and just all-around better for your tee (and the planet).
