Half the world’s forests have already been cleared

And the size of a football field continues to be cleared every second. At this rate we will lose all the remaining remnant forest within 100 years.
We want to turn this shit around. We’ve committed half our profits to supporting the planting of trees and the protection and regeneration of rainforests.

Saving forests and planting trees is one of the simplest and most cost effective ways of reducing CO2 in the atmosphere to tackle the climate crisis

Trees are incredibly efficient machines that suck up atmospheric carbon and turn it into a solid form, using free energy from the sun to lock it away. Not only do they capture carbon, they provide essential habitat for many species, and release oxygen for us to breath, bonus!

That’s why we’re committing 50% of our profits to planting trees and saving rainforest, everybody’s ass benefits, including the animals

We've partnered with

A passionate non-profit organisation and a growing social movement that raises awareness and funds for forest conservation and tree planting. Collaborating with tree planting organisations across the globe as part of the Trillion Tree Campaign.

We love the way they encourage folk each year to colour things up, clip, shave, or braid back their hair in a quirky, kickass way to fundraise and start the conversation.

HalfCut has been working tirelessly to raise funds to purchase and protect as much rainforest as possible and place it back under the care and management of traditional custodians.

Stay tuned for our HalfCut not Half Assed range coming soon.

Of course we’d love to be able to cover your ass with our smartass undies butt, if our underwear ain’t your thing, you can still be badass and donate directly to every dollar makes a difference.


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.
