These sheets bear the PerfectCale® trademark, denoting the finest-quality bed linens available at any price. These incomparable sheets and pillowcases are tightly woven with 500 threads per square inch of soft-yet-strong Pima cotton single-ply yarn so fraying or coarsening is never a worry. Guaranteed to never pill, these sheets will retain their luxurious hand and texture, providing years of extraordinary comfort and quality. Thomas Lee has also taken the extra step of completely encasing the elastic on each fitted sheet with PerfectCale® fabric so that it is completely, elegantly covered; ultra-deep 18-inch pockets ensure a perfect fit on any mattress. Much "luxury" today is hyperbolic, claimed, and more talk than anything else. Then there is that luxury that is felt, seen, and experienced. Thomas Lee's Pima cotton bedding falls under this blissful category and embodies luxury in its purest, simplest, and most inimitable form.
