The DEUTER Exosphere -11 SL women's sleeping bag (175 cm, left zip, ink/maple) is a single-layer, women-specific bag designed for cold-weather backpacking and alpine camping. With a declared comfort around -11°C and a slim SL cut for shorter female anatomies, the bag focuses on thermal efficiency, reduced weight and compact packability. The left-side zipper allows easy entry and exit while maintaining close body fit to reduce empty air volume and preserve warmth.
Advantages
This women's sleeping bag offers a combination of low-temperature comfort and a tailored fit thanks to the SL (shorter/contoured) cut. The single-layer insulation provides a favourable balance between weight and warmth for multi-day trips, and the left zipper improves convenience for users who prefer this orientation. The ink/maple colourway is durable for outdoor use, and the bag packs down to a size suitable for backpack carry.
Suitable for
- Cold-weather backpacking and trekking where sub-zero night temperatures are expected
- Alpine or mountain camping with a focus on low-weight gear
- Multi-day hut-to-hut or bivvy trips requiring compact sleep systems
- Female users up to approximately 175 cm who prefer a left-side zip
When it may not be suitable
This bag is not intended for extended winter use in extreme polar conditions or for users who sleep significantly colder than the manufacturer's comfort rating. The single-layer construction and women-specific SL sizing may feel restrictive for taller users or for those who prefer roomier mummy cuts.

How to use
Use the sleeping bag inside an appropriate groundsheet or tent to protect from moisture and abrasion. Fully unzip and shake the bag before first use to let the insulation loft. When sleeping, close the zipper and adjust any draft collar or hood features to minimise air movement and heat loss. After each trip, air the bag thoroughly and store it loosely in a dry place or storage sack to preserve insulation performance; for transport, compress into the supplied pack sack.
What to consider before purchase
- Compare the comfort temperature to expected night temperatures on your trips
- Confirm the 175 cm maximum user height matches the intended sleeper
- Decide if the left-side zipper and SL (women-specific) cut fit your sleeping preferences
- Assess whether single-layer insulation meets your warmth-to-weight needs
Usage recommendations
Pair the sleeping bag with an insulated sleeping pad and a breathable liner for improved warmth and hygiene. For wetter conditions, use a vapour-permeable bivy or waterproof outer layer to protect the bag from moisture without compromising loft.
