Us encouraging you to wash less probably doesn't come as a shock anymore. "I've heard this before – good for your clothes and good for the environment", you're thinking. But have you ever thought about how good it is for you?

Founder Jo has previously worn one of our tank tops in organic wool and silk for over 200 days without washing it, and it never started to smell. We have often used this example to challenge others to do the same.

This summer, Mats Mikalsen gave himself the challenge and wore one of our t-shirts for 70 days at work in the mountains. During those 70 days he only washed it once.

Luckily that's not a problem when you use nature as your washing machine. For Mats there were actually fewer problems: "I just hang ut out to air after use, and it's good as new. That way I don't need as many t-shirts, and not having to make a choice of what to wear in the morning is awesome!"

Good for your clothes, good for the environment and good for you.

Will you take on the challenge? Tag #buylessplaymore and show us how many days you have used your NP shirt without washing (you don't have to beat Mats and Jo 😉)
