WHAT WILL YOU USE YOUR SLEEPING BAG FOR?
FIND THE RIGHT SLEEPING BAG
HOW DOES A SLEEPING BAG KEEP YOU WARM?
A sleeping bag keeps you warm by insulating you from the outside temperature. The sleeping bag itself doesn’t generate heat, your body generates heat and warms the air inside the sleeping bag
then the insulation in the bag slows down the escape of the warm air you have created, the more insulation the better the bag will be at retaining the warmth and the warmer you will be.
