able to stay warm at night. When camping, even when it is very hot
during the day, it can be very cold at night. Lindsay decided to do
some research on sleeping bags.
Th e temperature rating of a sleeping bag describes the lowest
outside temperature at which the bag will keep a sleeper warm.
13. Look at each situation below and decide if the sleeping bag
is the correct bag for the temperature of the camping location
based on the rating of the bag.
