Thanks a unique dobby loom that can change weave structures throughout the warp and weft, this fabric contains two distinct weaves. Where the fabric appears solid, it's woven as a plain weave, while the dots are created by a unique open weave structure. Playful at first glance, these dots actually serve a functional purpose: ventilation. An open weave structure allows for even more air flow through the fabric, keeping you cool and dry even when temperatures rise.
