Firelight 750


The Firelight 750 is a lightweight, down sleeping bag that will keep you warm down to -14 Celsius. It weighs a mere 1100 g including its stuff sack, and occupies a volume ofsixteen litres when packed.

Its performance comes from the incredibly high-lofting, 900 fill-power, Polish goose down and the box-wall baffle construction throughout. The Firelight is made from a high-quality, 15 denier, Japanese-produced fabric whilst the foot area is protected by a Pertex Endurance water-resistant fabric.

The Firelight 750 is a very warm bag – too warm for normal use. Thus it is restricted to those venturing further afield, or more specifically, to higher altitudes or outside the main spring-autumn period. It is ideal for pre- or post-monsoon trekking in the Himalaya, or ranges such as the Andes. In short, this is the bag for mountain trekking.

It is available in 3 sizes and has a full-length zip.

Temperature Ratings

EN13537: -7˚C Comfort
-14˚C Lower limit
-33˚C Extreme


The comfort rating represents the lowest temperature at which a standard adult FEMALE can have a comfortable night’s sleep.

The lower limit represents the lowest temperature at which a standard adult MALE is deemed able to have a comfortable night’s sleep.

The extreme limit is a nonsense and best ignored. We really don't see any usefulness in this measure.

We like the EN13537 ratings at Lightwave. Going by our own extensive experience, we feel they accurately reflect the temperature limitations of each sleeping bag for a comfortable night’s sleep. Individual tolerances may allow some people to go beyond these figures, but we believe this is at the discretion of the user and is not something to be claimed by us.

Care & Attention

Down is a very resilient insulating material and, with basic care, any down sleeping bag should last you a very long time (if not your entire active climbing life). There are two simple rules to ensure longevity:
1. Always store your sleeping bag uncompressed in a dry, airy place.
2. Always use a sleeping bag liner. This will prevent the bulk of body oils and perspiration from getting into the down itself and reduce the need for washing the bag.

Although it is possible to machine wash these bags, we highly recommend you hand-wash your down sleeping bag or, alternatively, use a professional service. You can download washing instructions here.
