The Twin XL Mattress Barrier Cover provides protection against bed bugs and dust mites through its tightly woven GOTS certified organic cotton fabric. Constructed at 333 thread count with 30 single yarn, the material combines breathability with a dense weave that blocks allergens and pests. The cover is cut slightly larger than standard sizing to account for natural cotton shrinkage after washing, while a durable zipper closure allows for straightforward removal and laundering. Sized to fit mattresses and futons with a depth of 14–17 inches.
