How do I care for my sleeping bag?

Caring for your sleeping bag is easy. We recommend caring for your bag with the range of Nikwax products to help maintain water repellency and clean any soiled material.

Visit our ‘Caring for your sleeping bag’ page for full step-by-step instructions on how to care for your sleeping bag.  

What bag is best for me? Down or synthetic?

When choosing your Domex sleeping bag you need to decide between down or synthetic fill. Both types have advantages, so you need to decide which option best fits your needs. We’ve put together a table below that outlines the properties of down and synthetic bags.

Properties Down (natural goose or duck down) Synthetic (man-made fibres)
Warmth Molds to the body to create the best warmth – best heat retention per gram of weight ​ Good heat retention, but not as warm per gram of weight as down
Weight & compression Lightweight and packs up smaller than synthetic Slightly heavier and doesn’t compress as well as down
Wet weather ability Effectiveness is impacted when wet and takes longer to dry Keeps the user warm even when damp and is quick to dry
Lifespan Lasts longer when looked after well Less expensive but shorter lifespan
What shape is best for me?

When thinking about what shape to choose it is best to consider what type of sleeper you are plus the conditions you will predominantly using the bag in.

Mummy sleeping bags are wider at the shoulder and taper significantly at the foot – think Tutankhamunin in his sarcophagus. Mummy sleeping bags hug the body shape and keep the warmth in due to its narrower shape. Recommended in colder conditions.

Semi rectangular sleeping bags taper slightly at the foot of the bag. Semi-rectangular sleeping bags still taper towards the foot but a lot less than a mummy bag. This makes for a roomier sleep if you’re the type of person that likes to change sleeping positions often.

What is hydrophobic down?

Hydrophobic down is down that is treated with a water repellent solution. Down is the perfect insulator, until it gets wet. The insulating properties of down are greatly reduced once it gets damp and it is prone to breaking down if not dried thoroughly. All down used in Domex sleeping bags is treated with Nikwax, a market-leading water repellent treatment. With Nikwax Hydrophobic down you can be confident your Domex down sleeping bag will stand up to tough kiwi conditions.

What is a denier rating?

A denier rating is how the thickness of a material is measured. The higher the denier count, the thicker and stronger the fabric will be. Conversely the lower the denier rating the softer and silkier the fabric will feel.


All Domex sleeping bags are covered by a comprehensive 5-year warranty.
