Also, know as pique knit, this is not to be Piquée Knit confused with marcella pique fabric which is woven. The reason it is called that way is because of the characteristic, three-dimensional waffle look, also found in the marcella pique weave. Pique knit is not only flexible but also breathable, and, therefore, the most popular polo shirt knit. The scale of the waffle can differ tremendously, and different kind of knits are in existence. For more breathability, you want bigger holes, and for less weight, you want a smaller knit.
