Warmth that lasts – even when temperatures drop

Are you planning a winter tour, a high-altitude expedition, or a frosty bivouac in the snow? Then you need a synthetic sleeping bag you can rely on every night – the Deuter Exosphere -11°C is made for just that. With its high-performance insulation and clever features, it will keep you comfortable through freezing nights and ensure you wake up refreshed for the next day's adventure.

Sleeping comfort even below zero

Inside, a high-quality Thermo ProLoft® filling ensures reliable warmth. The innovative shingle construction with a 2.6-fold overlap effectively keeps the cold out, while the Thermo Stretch seams flexibly conform to your body. The result: significantly fewer cold spots and greater freedom of movement while you sleep – especially important when you want to recover after a long day in the snow.

The ergonomic foot area with its patented Ergofoot construction creates more space for your feet. Additionally, the integrated foot warmer function provides targeted protection against chilling in one of the most sensitive areas of the body.

Ideal for humid conditions

The Dryzone areas at the head and foot of the tent are made of water-repellent materials and reliably protect you from external moisture – whether from condensation inside the tent or from the cold ground during bivouacs. This keeps you dry and warm even in high humidity or when in contact with snow.

Sustainability meets functionality

This sleeping bag impresses not only with its technology but also with its sustainable production. The inner and outer materials are bluesign® certified and made from 100% recycled polyester. Furthermore, the Exosphere is PFAS-free and ClimatePartner certified – a plus for you and for the environment.
