CUMULUS® PREMIUM

This sleeping bag is equipped with the premium CUMULUS® inspection bundle offering two complimentary check-ups with servicing, plus professional sleeping bag washing for long-lasting performance.

MUMMY SHAPE

This advanced mummy shaped down sleeping bag is intended for long-term use under polar conditions and for high-mountain expeditions during the winter. Its advanced structure has been specially designed to maximise regeneration at extremely low temperatures.

DOUBLE “H” CHAMBER DESIGN

Advanced double H-shaped chambers system eliminates cold spots and ensures uniform insulation. While the differential cut allows the down to fully loft, providing optimal warmth and reducing compression during sleep.

3D SHAPED HOOD

3D-shaped hood paired with an independently adjustable 3D collar minimizes heat loss on cold nights. This combination offers a tailored fit and enhanced protection in extreme conditions.

ERGONOMIC FOOTBOX

Ergonomically shaped footbox with advanced insulation layout, offering superior warmth in one of the most cold-sensitive zones. Designed to maintain natural foot position while eliminating dead air pockets.

YKK® ZIPPERS

Durable, 120 cm long, 5 mm YKK® zipper with two self-locking sliders features an anti-snag strip for smooth operation. Twin down-filled draft tubes along the zip line ensure no heat escapes through the closure.

INTERNAL POCKETS

Two convenient inner pockets keep your small essentials, like a headlamp, battery pack, or phone, warm and within easy reach, even in freezing conditions.

COMPACT WARMTH

This down sleeping bag combines exceptional warmth with low bulk, making it ideal for high-performance use. Filled with premium, high fill-power down, it compresses efficiently to fit into an expedition backpack without occupying excess space.
