If you're backpacking, it doesn't make much sense to stuff a bulky pillow into your pack, when your fleece pullover could easily double as a one. But some people just can't sleep unless their heads are resting on a fluffy cloud of polyester cushioning. If you're one of those people, you might as well pack a camping pillow. If you're car camping, you don't have to worry as much about it taking up space in your pack. But if you're backpacking, you'll be happy to know that many camping pillows on the market are light (about 12 ounces) and that they often come with stuff sacks. Stuffing the pillow in the sack will make it compact and also keep it dry.
