The Ajungilak Shield braves the elements: Rain, blizzards, downpours – you name it, the Shield keeps you dry. It is the world's first waterproof and virtually seam-free sleeping bag, where even the head zone is protected from the rain by a stowable awning. There are no seams on the upper surface of the outer shell so the sensitive down stays dry – no matter how wet the weather.

Mammut's sleeping bag developers wanted a bag that cut the number of seams to a bare minimum, as every seam is a weak point. Amazingly, they managed to design an outer shell upper surface that is completely without seams. The ten necessary seams – bear in mind a conventional bag has between 35 and 40 of them – on the sides and base are fully taped.

This patent-pending seamless design means the bag is less prone to cold bridges, utterly waterproof, and boasts improved insulation. The Shield's dependable dryness in rain and snow applies from head to toe, thanks to the waterproof yet breathable membrane bonded to the shell's shelterTX fabric. If needed, an awning can be erected over the head – no need to leave the cozy bag to read or cook: The climber simply has to slip his arms through the two conveniently placed half-length zipper openings.

Thanks to the Ajungilak Shield's total weather protection, there's no longer need for a bivouac: The watertight bag is a sleeping and bivvy bag in one, but much lighter and more cost effective than the two separate items. The Ajungilak Shield has won the Outdoor Industry Award 2008.
