We didn’t reinvent rain.
Just the layer that deals with it.
Inside this garment is a dimpora® membrane: a layer just microns thin that keeps rain out, lets heat escape, and changes how technical protection feels.
Not bad for something you’ll never see.

Staying dry was always the job.
What changed is how we get there.

01The performance
You’re probably here for the numbers. Fair.
Waterproofness up to 20,000 mm (JIS L 1092). Breathability up to 5,500 g/m²/24h. (JIS 1099 A1)
We use JIS L 1092 for waterproofness and JIS L 1099 A1 for breathability because they are widely recognised in the industry and give a useful reference point. But test results are always shaped by the method behind them.
Different standards measure performance in different ways, and the same membrane can score very differently depending on the setup. Numbers help. They just do not tell the whole story. Real-life performance starts where lab conditions end.
Want to understand what those numbers actually mean? We wrote about it.
02How we got here
For decades, the waterproof layer inside outdoor gear has been made with PFAS and solvents — chemicals that don’t break down, that accumulate in water, in soil, in living things. Gear made for people who love nature, built with chemistry that harms it.
That contradiction bothered us enough to do something about it.
After years of research we built a completely different process. One that creates waterproof breathable membranes without PFAS, without solvents, and with possibilities that simply didn’t exist before. We call it CoreLayer™.
The high-performance membrane in your jacket is the result.
03About this garment
This garment uses dimpora® BIO, the first membrane out of CoreLayer™.
Over 60% bio-based
Made from castor oil. A renewable crop that doesn’t compete with food production or drive deforestation. The remaining synthetic part is there by design, it’s what makes it perform.
We’re working on pushing it further. But not at the cost of the performance you bought this garment for.
Sustainability is a journey. We’ll tell you exactly where we are, including the parts we’re still working on, because we think you deserve that more than a clean story.
Still no forever chemicals. That was always the starting point.
04The people behind this
We’re a team of engineers, scientists, and materials specialists based in Zurich. We wear the gear we help make. We love nature. And we take membranes dead seriously — probably more than is entirely healthy.
