Mammut introduces the lightweight Ajungilak Alpine Ultralight
Mammut’s 2011 synthetic sleeping bag used MTI 14 insulation, with a listed weight of 990 g for the 195 cm version.
Mammut introduced the Ajungilak Alpine Ultralight in 2011, describing its new MTI 14 filling as a breakthrough in synthetic sleeping-bag weight and packed size. The design aimed to reduce the load without giving up the features needed for a night outdoors.
The 195 cm version weighed 990 g and had a stated women’s comfort temperature of −2°C. MTI 14 filling and lightweight inner and outer fabrics contributed to the low weight. The TX outer fabric was described as wind-resistant and moisture-repellent.
Internal seam tape helped limit cold spots, while the slim shape reduced unnecessary bulk and weight. A close-fitting Performance hood with Advanced Visibility was intended to protect against cold while allowing a good view even when closed.
