Mammut Ajungilak Kompakt 3 Season (2012)

The Ajungilak Kompakt is an extremely well-established classic synthetic 3-season sleeping bag. At 1850g it is heavier than equivalent down bags, but as it’s filled with a good-quality synthetic insulation it feels slightly warmer than other bags of similar temperature ratings. The bag’s stuffsack comes with compression straps so it can be cranked down to a respectable size. The bag benefits from a good anti-snag strip behind the full-length side zip as well as a wide draught excluder on the inside of the zip. This makes the bag easy to use and free of cold spots in this area. The hood is packed with insulation too and it’s easy to adjust to create a good, snug fit. There is no shoulder baffle, but there is an additional shoulder drawcord that helps to trap warm air inside. The Mammut Ajungilak Kompakt 3 Season is a very warm 3-season bag with all the benefits of synthetic insulation.
