Established in New York in 2014, PH5 is an advanced contemporary women’s knitwear brand founded by Wei Lin, the daughter of a large knitwear manufacturer, and created by a Parsons-trained, award-winning designer, Mijia Zhang. 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.
