The sheets make the bed

Before designing our sheets, we had to rethink everything we thought we knew. We learned that a higher thread count doesn’t mean higher quality, you can’t cut corners when it comes to cotton, and the right weave makes a world of difference. Our result? Sheets that are the perfect balance of soft, crisp, and airy.

Softness that lasts

Grown in California’s 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.

What is extra-long staple cotton?

In the cotton industry, staple is just another word for fiber. Extra-long staple cotton is made up of long continuous fibers (with very few exposed ends). Regular cotton is made up of many shorter fibers strung together (with lots of exposed ends). Because it’s so smooth, 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

We 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.

Percale Illustration

Percale

Percale 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.

Sateen Illustration

Sateen

Sateen 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.

Threads that count

Instead of obsessing over the number of threads, we focused on finding the right thread count for our specific cotton and weave choices. A high thread count sounds fancy, but more threads can actually make sheets heavier and less breathable. We landed on 400 two-ply threads — a modest number that makes a big difference.
