Verification Technology

At PimaCott, we've got pima cotton purity down to a science. We start by authenticating our pima cotton through a process called fiberTyping®. This patented genomic test confirms that the pima from our farms is indeed pure pima. Then, we tag our pima with SigNature® T. This invisible molecular marker allows us to track every fiber at every phase, from farm to store. Our pima is repeatedly tested for purity. So when it becomes a final product, you can be sure it contains nothing less than the purest premium pima — and that’s a fact.

WHAT IS SigNature® T?

SigNature T is an invisible molecular marker that allows us to tag, test, and track PimaCott pima cotton at every step, from dirt to shirt. We can ensure our pima is never blended with inferior cottons. So the pima we grow is the pima you get: soft, strong, and proven pure.
