Thermo Pro Loft®
In a special thermal procedure, the polyester fibres are processed to create a technical high-performance Thermo ProLoft® insulation fleece. The ideal relationship between durability, weight and warmth is guaranteed by this mix of full and hollow fibres. This combination creates a fleece that is robust, easy-care and easily stowable, whilst also offering excellent warmth insulation at the lowest weight possible. In addition, the synthetic fibres absorb little moisture. Short drying times and outstanding loft volume, leading to efficient warmth retention even in damp conditions, are among its main benefits. In addition, the Deuter Thermo ProLoft® is treated with a thin silicon layer for better filling performance.

  • * D stands for denier. This describes the yarn weight. 600D corresponds to 600 grams per 9000 meters.
  • * PES stands for polyester. PES fibres are very tear and abrasion resistant and hardly absorb moisture.
  • * PA stands for polyamide. PA fibres are extremely durable and abrasion-resistant. They are also characterized by high elasticity and low weight.


0° C
THE COMFORT TEMPERATURE is based on the lowest temperature at which an ‘average’ woman (25 yrs. / 60 kg / 160 cm) can expect to sleep comfortably in a relaxed position. This range ensures a comfortable sleep, also for inexperienced users.
-6° C
THE LIMIT TEMPERATURE is based on the lowest temperature at which an ‘average’ adult male (25 yrs. / 70 kg / 173 cm) can expect to sleep comfortably in a relaxed position. An experienced user can optimise the insulation qualities by his choice of clothing and further factors.
-23° C
THE EXTREME TEMPERATURE is a survival only rating for an ‘average’ adult woman. They won't be able to sleep, but they will reamain alive for six hours without the risk of death by hypothermia. Nevertheless there will still be a risk of other damages (such as frostbite).

Top features of the Exosphere -6° SL

SL Sleeping Bag

SL Sleeping Bag

The right size and shape ensure that no unnecessary air has to be warmed up. deuter’s REGular models are ideal for people up to about 185 cm height. The larger, similarly equipped L versions are for people up to about 200 cm tall.

The shorter SL Women’s Fit versions also feature fluffy fleece inserts around the kidney area and at the feet. They are ideal for women up to 175 cm tall.

PFAS free

PFAS free

This deuter product is free of intentionally used PFAS (per- & polyfluorinated chemicals). deuter thus reduces the use of substances, that are known to harm the environment and health.

For Outdoor products PFAS are mainly used for water repellant treatments.

Instead, deuter uses since 2019 alternative DWR (Durable Water Repellency) impregnation.

Carbon neutral product

Carbon neutral product

By adopting more materials and technologies that have a smaller carbon footprint in our collections we are taking positive steps toward reducing our CO² emissions. But despite our greatest efforts, it’s impossible to make products climate neutral. And so, we’ve teamed up with Climate Partner to offset any unavoidable CO² emissions. From now on, the volume of emissions released by the production and transport of any ‘Carbon neutral’ deuter product purchased will be compensated for through voluntary offsetting and targeted investment in select social and climate protection projects.
