Running is a huge category for us. To be able to run to work and have lightweight, breathable, windproof materials you can chuck in your bag that work on technical level but also on a lifestyle level are really important to me.

I'm not offended or embarrassed by the fact that I design clothes for women to wear. So when I meet women who love my clothes, it's a really good, straightforward thing. It makes me feel like I'm doing my job right.
