Just like any natural fabrics, on a very rare occasion, it is plausible that pilling may occur after initial use of the bamboo fabric. This is completely normal for natural fibres, especially in response to friction and isn't classed as a fault or defect. As our care instructions will inform you, this issue is usually removed during 4-5 washing cycles. Due to our products being manufactured using a twill weave, it is less likely for pilling to occur than a sateen weave.
