The Kuul Thread Performance Shirt


Heat Regulating Fabric or PHASE CHANGE MATERIALS (PCM) were first developed for NASA to protect astronauts from the extreme temperature fluctuations in space. Kuul Thread utilizes for its dress shirts, PCM fabric that absorbs, stores and releases heat for optimal thermal comfort. This technology gives the ability to continually regulate skin's micro climate. As the skin gets hot, the heat is absorbed, and as it cools, that heat is released. Our dress shirts will proactively manage heat while controlling the production of moisture (sweat) before it begins. This is not your typical wicking shirt which traps heat and creates discomfort. Our dress shirts will minimize sweat and balance skin temperature to create comfort.

The cooling technology powering our dress shirts, is embedded in every fiber
and it will keep performing for the entire lifetime of the garment.


Craftsmanship and design that cannot be imported. Design, Performance Fabric and Manufacturing are all done in California. Manufacturing in USA was a conscious decision to embrace local manufacturing as a vital component of our business strategy. We manufacture locally because it makes sense, for branding identity, infrastructure capacity, local supply chain and skilled workforce.
