Price Transparency

Yup. We know. It’s not cheap. So what makes HAVN more expensive than your average big bucks store garment?

#1, the fabric. Our proprietary fabric uses over 40% of silver fibers and cost the same to produce as cashmere. This is not counting the R&D cost in order to make it soft and cozy.

#2, the manufacturing. We care about making the most premium, high-quality clothing on the planet. To ensure this, we partnered with a factory that pays equitable wages, offers fair time-off, and is certified OEKO-TEX – the highest environmental rating. This commitment also means we pay a ~30% premium on manufacturing, a choice we proudly stand by.

#3, the quality-control. You trust us with your long-term health. We take this seriously. That means that we have increased quality control to ensure every production batch is respecting our highest quality standards.

All in, our cost of production is ~10x that of a normal, equivalent piece of clothing. Now, we could (maybe) do it without #2 and #3. But it wouldn't be right. It wouldn't be HAVN. Our commitment? With us, you will always get what you pay for.
