A mummy sleeping bag filled with white goose down, the insulation serious cold-weather campers still choose because nothing else matches it for warmth against weight. The shell and lining are both nylon, and the tapered mummy cut reduces the air your body has to heat. It comes in standard and lengthened versions, so taller sleepers are not left with cold feet pressed against the end.
Why Customers Choose This Product

- Mummy cut for heat retention
- Nylon shell and lining
- Standard and lengthened sizes
- Compresses well for packing
Product Highlights
Down, Not Synthetic
Goose down traps more warmth per gram than any synthetic fill and compresses far smaller in a pack. For cold, dry conditions it remains the benchmark.
A Shape That Keeps Heat In
The mummy cut tapers towards the feet, so there is less dead air for your body to warm. A rectangular bag of the same fill will always sleep colder.
Two Lengths
The lengthened version suits taller sleepers. Being cramped in a bag is not just uncomfortable, it compresses the down and costs you warmth.
Packs Small
Down compresses in a way synthetic fill cannot, which is why it is still the choice when space in the pack is tight.

Important Information
- No temperature rating is listed for this sleeping bag, and it is the single most important specification for cold-weather use. Contact us before ordering and we will request the comfort and limit ratings from the supplier rather than guess.
- Fill weight and fill power are not listed either, and both determine how warm a down bag actually is. We will ask for these alongside the temperature rating.
- Bag dimensions, packed size, and weight are not given for either version. Get in touch if you need them.
- Down loses its insulating ability when wet and is slow to dry. Use a dry bag or waterproof stuff sack in damp conditions.
- Store a down bag loose in a large sack rather than compressed. Leaving it stuffed permanently flattens the down and costs you warmth.
- Follow the care label. Down needs specialist washing, and ordinary detergent strips its natural oils.
Frequently Asked Questions
How cold can I use it in?
No temperature rating is given in our supplier data. We would rather tell you that than invent a figure, so contact us and we will request it before you order.
What is it filled with?
White goose down.
What is the difference between the sizes?
A standard and a lengthened version. Exact dimensions are not listed, so get in touch if you need them.
Why a mummy shape?
It tapers towards the feet, leaving less air inside for your body to heat, which makes it warmer than a rectangular bag of the same fill.
How should I store it?
Loose in a large storage sack, not compressed. Keeping down permanently stuffed damages the loft that keeps you warm.
What if it gets wet?
Down insulates poorly when wet and dries slowly, so keep it in a dry bag when conditions are damp.
