A waterproof shelter, sleeping bag and sleeping pad are three of the most important pieces of kit you’ll need when bedding down in the great outdoors on a cold night. Usually those three things are purchased, packed and set up separately, but Swiss startup Polarmond has a different idea. Its All-In-One sleep system rolls all three components into one unit with the goal of delivering a warmer, more comfortable night of sleep in temperatures down to -22° F (-30° C).
The primary component of the All-In-One sleep system is what Polarmond calls the sleep shell. This unit blends the features and functions of a bivouac sack, sleeping bag and sleeping pad. When compared to the tight confines of a mummy bag, the design opens things up with a multi-layered inner chamber.
