Softness that lasts grown in California central Valley, our premium extra-long staple Supima cotton is one of the finest and longest fibers in the world. It won't pill or wear thin – it will only get softer with every wash.Why extra long our extra-long staple cotton is made up of long continuous fivers (with very few exposed ends), regular cotton is made up of many shorter fibers stung together (with lots of exposed ends). because it's so smooth, our extra-long-staple cotton can be used to make threads that are four times stronger and softer than the average cotton thread. A weave that breathes chose a lightweight percale weave because it's proven to last longer and breathe better than any other. It features a classic one-over-one pattern that will give you cool, crisp comfort for nights on end. What makes percale better our percale weave is a classic one-yarn-over, one-yarn-under weave. This method produces a structurally sound fabric that will last longer and allow more air to pass through it. Whereas, many other sheet companies is a sateen weave which is a one-yarn-under, three-yarns-over weave. This method exposes more of each thread, giving it a shiny finish. The catch-it also traps air and makes the fabric more susceptible to snags.

A high thread count sounds fancy, but more threads can make sheets heavier and less breathable. We landed on 400 two-ply threads. They're a hit!
