Cost of a Sleeping Bag

Camping: Cost of a Sleeping Bag How much does a sleeping bag cost? Let’s say you want a sleeping bag that should keep you warm in temperatures from 20°F to 45°F. A random sample of prices ($) for sleeping bags in this temperature range was taken from Backpacker Magazine: Gear Guide (Vol. 25, Issue 157, No. 2). Brand names include American Camper, Cabela’s, Camp 7, Caribou, Cascade, and Coleman.
