Our original performance fabric sheets feature four-way stretch capabilities and are guaranteed to fit extra-deep and pillow-top mattresses. Our fitted sheet features ultra-strong elastic around the bottom to fit snugly around your mattress without popping off. It's the best-fitting sheet you can find anywhere.

Yes! We offer a special product we call a "Split King" set that features this exact configuration. This product is available in our original performance fabric.

We ship within the United States, U.S. protectorates, APO/FPO addresses and Canada. International shipping is subject to shipping charges.

We proudly offer a full range of complimentary products that work together to help your body stay at its ideal temperature and improve sleep. Additional products in the SHEEX® family include duvet covers, pillows, comforters, mattress pads, and even a mattress. Plus, our performance fabric sleepwear and loungewear is available in both men's and women's styles.

Twin/Twin-XL sets include one standard pillowcase. Full and Queen sets include two standard pillowcases. King, California King and Split King sets include two King pillowcases. All sets (with the exception of Split King) also include one fitted sheet (also known as a bottom sheet) and one flat sheet (also known as a top sheet).

In our Nautical Collection, Bunk sets come with one standard pillowcase; Double/Queen, Forward/Hex, V and V XL sets come with two standard pillowcases; King comes with two King pillowcases.

Because of the unique circular-knit microfiber technology used in our performance fabric SHEEX®, the concept of thread count does not apply like it does with traditional cotton sheets.
