Our products are made in modern well-equipped factories where staff have safe and fair working conditions.

We source packaging that is made from recycled as well as biodegradable materials.

The high-performance engineered fabric feels like cotton but will outperform and outlasts natural fibres.

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 to bring you a high-performance material. It wicks away moisture, odour and heat, dries superfast, maintains its shape life long, is highly durable, low impact, soft to touch and damn comfy.

We believe that taking care of our environment is important for all our asses.

5% of our profits go to planting trees and other measures to off-set our carbon footprint and reduce our asses impact.

We are proudly partnered with Greenfleet for the planting of trees to absorb carbon emissions, reduce soil erosion and salinity, and increase native habitat for wildlife.
Everybody's ass benefits, including the animals.


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!

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.

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.
