Firelight 750

The Firelight 750 is a high quality, lightweight down sleeping bag that is ideal for use in temperatures down to -15°C. Please refer to the detailed information on temperature ratings below and click here for help on choosing a bag.

Manufactured wholly in Poland, the Firelight 750 is filled with the famed Polish white Goose down that is 100% ethically recovered (read more here). . The down has a fill-power of 900 cubic inches as measured by the EU norm (and is equivalent to 970 cubic inches using the US standard).

The Firelight 750 has a full length zip that lies on the top of the bag. The zip is protected by a double baffle. There is a full neck collar that can be adjusted to close completely around the neck to provide a complete seal.

The Firelight 750 comes in three sizes and is supplied with a compact stuff sack and a large storage bag.

Fill

Fill weight: 750 g (size M)
Fill power: 900 EU (970 US) white Polish Goose down

The most important part of a sleeping bag specification as the combination of fill weight and fill power (FP) is what provides the sleeping bag's ability to insulate.

750 g of 900 FP down will fill the same volume as 840 g of 800 FP down or 700 g of 950 FP down.

Construction

Baffles: Slant box wall on top and bottom
Hood:  Fully adjustable cowl
Neck:  Full adjustable baffle
Zip:  Full length #5 YKK
Zip baffle: Double

The construction describes how the down is held in place (otherwise all the down would fall to the bottom) and what features are incorporated to maximise heat retention or, conversely, regulate your temperature. The Firelight 750 has sufficient down fill to warrant more sophisticated features such as a full-length side baffle, double zip baffles and an insulated neck baffle.

Fabrics

Shell:  29 g/m² 15 denier nylon (Pertex Quantum)
Lining:  29 g/m² 15 denier nylon (Pertex Quantum)

Lightweight fabrics allow the down to loft and reduce the weight of the bag. Although there are lighter-weight versions of the Pertex Quantum fabric we are using, they offer a negligible saving in overall weight and, having a lower tear strength, are easier to damage.

Bags:

Stuff sack: 25 g
Storage bag: 75 g

The Firelight 750 is an excellent all-round bag for those who are planning treks in the Himalayas. It is warm enough for year round alpine climbing up to 3000 metres. Its versatility is similar to that of the lighter Firelight 650 model, but more for those who want to err on the side of always being warm rather than risk the chance of the occasional cold night.

In 2005 the European Standard EN 13537 became the official standard for the labelling of sleeping bags in the European Community. The standard is not mandatory.

Although there are four different measurements, the two most useful (and in our experience reasonably accurate) ones are:

EN13537 Comfort rating  Temperature at which a standard adult female can have a comfortable night’s sleep.
EN13537 Lower limit   The lowest temperature at which a standard adult male is deemed able to have a comfortable night’s sleep.

The Firelight 750 is available in three sizes. All come with a left zip only.
