Established in New York in 2014, PH5 is an advanced contemporary women’s knitwear brand founded by Wei Lin, the daughter of a knitwear manufacturer and designed by a Parsons-trained, award-winning designer, Zoe Champion. The label challenges the conventional vision of knitwear by marrying whimsical designs with architectural dimensions of knitting techniques.

PH5’s moniker is based on the numeric pH scale, which ranges from 0 to 14, with 7 as neutral. If 7 represented androgynous unisex labels and 1 represented the extreme feminine or sexy brands, PH5 would be a brand that's leaning more towards the edgier side while keeping a touch of femininity. 

Innovative, functional and hugely stylish knitwear is at the heart of PH5. Empowered by its scientific name, PH5 is set out to inspire people to completely rethink knitwear and tell the world that knitwear is more than just a winter fabric. Knitwear is breathable, lightweight, colorful and fashion forward. 

Using knit as our vehicle of innovation, we are here to create a fashion label that reaches beyond womenswear, but into other categories and industries. By collaborating with many innovative tech firms, we are redefining the relationship between fashion and technology, which is what will allow us to succeed long term and create value in the world. At PH5, we are designing beyond products; we are redefining knitwear and what knitwear can be for generations to come.
