These do appear to be quite expensive compared to other brands however posting since 20% off is a deal and I'm always for supporting local business.
These are designed by a young Wellington based clothes designer (but made in Australia) that I read about in the paper not long ago. I found an article Stuff did on her here if you are interested: https://www.stuff.co.nz/life-style/fashion/103912175/designe…
The company promotes themselves as using ethically sourced materials, sustainability (such as using recycled PET bottles) and quality. They have some funky designs that appealed to my partner although she did highlight to me that 2mm wasn't the most practical thickness for Wellington where we are based.
