Cumulus Aerial 330

The Aerial 330 sleeping bag, with its specialized construction, was developed for uncompromising users seeking the lightest possible outdoor equipment. The excellent weight-to-insulation ratio of the sleeping bag is not only the result of choosing ultralight fabrics and 900 FP down fill, but also of innovative development processes.

When sleeping outdoors, the primary insulation on the underside is the sleeping pad, as part of the insulation on the underside of a down sleeping bag is compressed by the sleeper's body. Therefore, to reduce weight, the Aerial series uses only a single layer of the ultralight Toray Airtastic™® fabric on the underside, eliminating the need for additional down. The precise construction of the trapezoidal baffles and the absence of a zipper position the Aerial 330 sleeping bag among the top products with ultralight characteristics. The sleeping bag's weight of 483 g with a comfort temperature of -1 ℃ is an unbeatable result for traditional down sleeping bags.

Extreme adventure races, ultracycling, or multi-day treks in technical terrain are scenarios in which the minimalist Aerial sleeping bag series performs optimally. Its unparalleled effectiveness is appreciated by everyone who counts every gram of equipment carried on their back.
