Designers of backpacks use exotic material such as super nylon Delrin, high-density polyethylene, aircraft aluminum, and thermomolded foam to make packs that fit comfortably and distribute weight to eliminate pressure points. The following data show the capacity (cubic inches), comfort rating, and price for 10 backpacks tested by Outside Magazine. Comfort was measured using a rating from 1 to 5, with a rating of 1 denoting average comfort and a rating of 5 denoting excellent comfort (Outside Buyer’s Guide, 2001).
