The Morpheus 4 is a 4 season sleeping bag with an array of traditional and unconventional features.
The benefits of down, its warmth, light weight and compressibility are well known, but the ease with which down compresses can reduce the warmth provided underneath you. Add to that, the reduction in warmth that occurs when down gets wet and down sleeping bags are not always the magic solution. The Morpheus 4 Down/Synthetic sleeping bag is a hybrid bag created to get the best of both worlds - the benefits of down with the advantages of synthetic. Using Pyrotec™ polyester microfibre insulation in the base of the bag, you get warmth with a good barrier against moisture. The upper is filled with 650 Fill Power Hydrophobic European Duck Down for maximum warmth.
As a result of these innovations the Morpheus 4 is ideal in variable conditions (especially wet ones) any time of year.
A combination of ¾ length zip on left side and ¼ length zip on the other allows you to sleep with your arms out of the bag, a real benefit for such a warm bag, especially if you are using it in milder conditions. For yet more comfort the bag is designed with an extra wide mummy cut. The zips have anti snag guards and there's an internal pocket for stashing things you want close at hand through the night
