Sheets' durability and longevity depend on two main features. The length of the fiber and how aligned the fibers are in a yarn. Longer fibers last much longer and pill far less than shorter fibers. Also, the more aligned the fibers are, the better the overall durability is.
Sweet Zzz bamboo sheets fibers are extremely long and very aligned, ensuring they last for a very long time. This is exactly why we confidently offer a lifetime warranty on them :)
