Zentek Clothing

Zentek Clothing designs and manufactures quality thermo-regulating (phase change) clothing for both dogs and humans.

Zentek was founded in 2007, by Janice Kajanoff, to solve the problem of overheating dogs. She almost lost her first bulldog because of overheating. Trained in clothing design and textiles she used her skills learned at the U of W, and 30+ years as a custom designer. Once she found a phase change material, which holds a set temperature , she was off and running.Literally.. all over the US and Canada, testing and perfecting her model on the top show and sporting dogs . She received a U S patent for her dog coats in 2010.
Trained that fit is just as valuable as function, Janice found that there was a lack of good design in the growing market of canine coats.
Now she is using her considerable knowledge about phase change material to create clothing for the climate changes we are experiencing.

Researching performance fabrics like Comfortemp®, which regulates body temperature, Janice used her knowledge of proper fit to design a line of breathable, water-resistant and temperature-controlling coats for dogs.

Inspired by the blissful comfort and performance technology of her line, Janice named her company Zentek Clothing, as a symbol of the blending of these essential elements.
