These are a very special design of water-proof sleeping bags. These are made with a new-age material which stops moisture, including rain, from entering the interior sleeping compartment but allows perspiration to transfer from the interior to the outside. These are certified by EU at -20 degrees Fahrenheit. These bags are, also, 100% wind proof by design. Large baffles are along the entire zipper + a neck guard + a chest guard.
A Regular sized bag, it measures 34 inches at the shoulders and 86 inches in length. This is ideal for most adults. Weighing 6.8 pounds, this bag offers outstanding capabilities at a very low weight.
