What bedding do I need for a Twin XL bed?

For a Twin XL bed, you'll typically need a Twin XL fitted sheet, a flat sheet (optional), a mattress protector, one or two pillows with pillowcases, and a blanket or duvet that either matches Twin XL length or is sized for a twin/single but long enough to drape comfortably. In dorms, an extra blanket or throw can be handy for colder nights.
