Online shopping is great - But manufacturing, shipping, and in turn, the disposal of what we buy, leave a pretty big ecological footprint on our beautiful planet.

Carbon offsetting is certified system in which we calculate the total environmental impact of each order made through our Saisei store. We will then convert the negative impact to a dollar amount that will we invest in 'green projects' like reforestation, water purification, or beach cleaning. These projects will literally help us clean up the mess we made, and make your purchase - Carbon Neutral.

You have to admit, it's pretty cool..!

At checkout, you will have the opportunity to pay for your purchase's environmental impact to be offset into a 'green project' contribution. We calculate and operate the carbon offsetting through EcoCart, which charges an operation fee that is paid by Saisei, regardless of your contribution.

Choosing to pay for your purchase to be "carbon neutral" is effectively making sure your purchase is doing good - good for you, and good for our planet!

We are welcoming new members to the Saisei family as brand ambassadors. Believe in our mission, values, and style and want to take part? Please email Danny@saisei.co with your Instagram handle and email, and Danny will get back to you.

Every garment deserves a happy ending! Starting 2022, we will provide a garment recycling service that will make sure you old Saisei undies will get another life and turn back into yarn then fabric, then a fresh new garment.
