Mammut Little Mammut MTI

Meet the Little Mammut MTI by Mammut, a compact sleeping bag made for cooler nights in the backcountry. It’s built to provide dependable warmth without weighing you down, whether you’re heading out on a weekend trip or winding down at camp after a day of hiking.

With a comfort rating of –2 °C, the Little Mammut MTI uses 100% polyester fill to trap heat even if conditions get damp, and a tough 100% polyamide shell that helps shed light moisture and resist wear. Weighing in at just 850 grams and offered in two lengths (140 cm and 160 cm), it keeps bulk to a minimum in your pack while still giving you enough room to settle in for the night.

The –2 °C comfort temperature denotes the lowest ambient temperature at which an average sleeper can rest comfortably without extra layers. Polyester insulation works by holding pockets of warm air in synthetic fibers and retains loft when wet, unlike some natural fills. The polyamide outer fabric adds abrasion resistance and breathability, helping to limit condensation inside the bag and maintain its insulating performance.
