We don’t need another bulky winter jacket.
But one that understands how temperature regulation really works.
That’s why we took a completely new approach in developing this piece: For the first time, we’re using graphene in thermal insulation. This highly conductive material is already trusted in our high-performance products, especially when it comes to heat management.
In the Aethera, it works in a similar way: The integrated graphene distributes body heat evenly, stores it, and releases it when needed. The result is a stable microclimate – whether we're in motion or taking a break.
And because graphene itself adds virtually no weight, the jacket remains extremely light and packable. Perfect for anyone who likes to travel light – whether in everyday life or during winter adventures on the bike.
- Ultra-light winter jacket with graphene insulation
- Unique temperature management
- Packable – minimal volume, easy to carry
- Water-repellent finish with eco-friendly C0-DWR (fluorocarbon-free)
- Versatile use: daily wear, training, bikepacking
- Adjustable hem


Suitable for temperatures between 23 and 50 °F.
