BedVoyage Bed Sheets are 100% Rayon from Bamboo, are subtly cool and extremely breathable, with a feel softer to the touch than a 1,000 thread-count Pima cotton. The linens will not pill nor fade. Rayon from Bamboo is an easy care and durable fiber, and those with sensitive skin will benefit from the round fibers which are extremely smooth against the skin. Sheet sets includes 2 Twin XL deep-pocket fitted sheets, a King flat sheet, and two King pillowcases.
