You may carry enough food to sustain you for one day in a simple (non-magic) sack or bag. You may carry and use a spell component pouch. You may not use any magic item of an sort, though you can benefit from magic items used on you behalf - you can drink a potion of cure serious wounds a friend gives you, receive a spell cast from a wand, scroll, or staff, or ride on your companion's ebony fly. You may not, however, borrow a cloak of resistance or any other magic item from a companion fit even a single round, nor may you yourself cast a spell from scroll, wand, or staff.
