MummyPod will let you sleep on the terrain or in the trees without any problem. The Mummypod product is the first ever designed for both hammock and camping. It is available in a compression bag the same as any regular sleeping bag. However, the foot box easily opens to let a hammock through it. As soon as you cinch down the top and base drawstrings the case traps in warm air, trying to keep you warm all through the night. Abrupt rain storm or a little bit of dew pass through overnight? No reason to worry. The component that makes up the bag is formed from a VitalDry DWR layer while the 800+ fill is created from a hydrophobic down – making sure you’ll stay warm in spite of the situation. Temperature ratings on such bags begin at 30 and go straight around 0 degrees Fahrenheit.
