Sheets materials & construction

The Casper sheets are designed in the USA with 100% Supima® cotton from California.

Breathable weave

Our percale weave is more breathable and longer lasting than other popular weaves.

Ideal thread count

We discovered that 400 two-ply threads is the perfect count to balance softness, strength, and breathability.

Extra-long staple Supima® cotton

Grown in California’s Central Valley, our cotton is four times stronger than the industry average, so the threads don’t pill or pull.
