We care about how our products are made and what they’re made of.

That’s why we’ve partnered with Specortex who have engineered our undies fabric from recycled PET (polyethylene terephthalate). Taking soda and water bottles and transforming them into high performance polyester fibre.

With over a million single use plastic bottles being discarded every minute, most ending up in landfill, or worse, in our oceans, at smartass undies we’re committed to being part of the solution.

We choose to source sustainable materials because we choose to have a cleaner planet and business.

We’re committed to turning a problem into a solution.

Testimonials

Seriously the most comfy undies I have worn. Love that the packaging is biodegradable and the undies are made from recycled materials. So every morning I get the reminder of ‘KINDNESS’, to ‘NEVER QUIT’ to ‘MEDITATE’, and that ‘HAPPINESS IS A CHOICE’. How great is that, highly recommend every part of smartass undies from the order to arrival and wearing.

I love that these smartass undies are super soft and comfortable! They fit snug on my body and I can’t believe that they are made out of recycled plastic bottles! I am all about being eco-conscious as possible and I love the fact that this company is eco-friendly on all levels! Plus, the motivational messages are hilarious and keeps me uplifted when I’m wearing or not wearing and just seeing it in my drawers!

I like the smartass undies because they are comfortable to wear with a good fit.
And especially the message behind about a smile, that cost nothing butt brings much reward.

A great pair of comfortable underwear that fit and wear well. They dry super fast after washing so great for hiking and camping. The procrastination quote keeps me getting shit done on a daily basis and a smile on my dial. They make a great gift idea.

Comfy underwear with attitude! Who would have thought you could turn to your underwear for inspiration and motivation. Well that is exactly what you get when you put on your smartass undies. A quirky reminder that the power of positivity is fundamental to your health and well-being.

Hi, I received my smartness undies, a pair of stylish, comfortable black underpants, with a fun message on my backside, printed in white so it stands out. Pity it can’t be seen when I am wearing pant over the top.
