There's always some new gizmo or gadget on the market; and with so much gear out there, it's easy to get confused. Corbridge takes away the guesswork with gear tables in each chapter that tell you where to buy the items discussed; the tables list the specific model, manufacturer, price, weight, and website. Carol's done all the research for you over several years of trials and many miles of trails.
