Yosuke Aizawa founded White Mountaineering in 2006 after a stint at Comme des Garçons under designer Junya Watanabe, the protégé of CDG (and Dover Street Market) founder Rei Kawakubo, and four years in the Department of Product and Textile Design at Tokyo’s Tama Art University. Needless to say, Aizawa has some serious design skills. He uses the White Mountaineering label to flex them, but also apply them to the outdoors, a kind of divine source of inspiration for him over the course of his career.
While his time at CDG offered experience with higher-end materials, luxury construction and appealing to an international audience, his own label represented freedom to step outside the fashion world — pun intended. There are three guiding principles in play whenever Aizawa designs for White Mountaineering, design, utility and technology. Plus, the belief that the “field in which we wear clothes is all outdoors.”
“I believe that what is most important for a fashion designer is not to limit your mind to the fashion industry,” Aizawa says.
For Aizawa, his new collab, an outerwear-centric collection with Japanese brand Uniqlo, represents expansion. Uniqlo is a big brand with over 40 locations in the US alone. Considering White Mountaineering has just one (1) brick-and-mortar stockist in the US, this furthers Aizawa’s reach fortyfold. (WM is carried in several US-based retailers’ online stores, but Hatchet Supply in LA is the only shop with in-person supply.) But this collab was about not all about numbers. Aizawa seized the opportunity to design for children, citing Uniqlo’s willingness to produce clothing for all people — adults and kids and a wide range of sizes (XXS through 3XL).
Uniqlo x White Mountaineering: refined outerwear for the entire family.

Staying in line with White Mountaineering’s outdoors-centric mission, the collaborative collection covers several types of outerwear: Parkas, pullovers, down jackets and fleeces that start at $20 (for kids) and max out at $150, a significant departure from White Mountaineering’s usual pricing.
