EmberLinie USB Heated Sleeping Bag with 4 Warmth Zones

Nightmares in the Cold

Never LetFreezing Nights Spoil Your Wild Adventures

Wild camping in the Scottish Highlands, pitching up on the Cornish coast or bedding down in a campervan: wherever you sleep, cold draughts wreck your rest and drain your energy.

Constant Shivering & Cold Feet

Traditional sleeping bags simply hold in the body warmth you already have. Climb in with icy feet or cold hands and you may shiver for hours.

Bulky Extra Blankets & Heavy Packs

Heavy thermal jumpers, leaky hot water bottles and spare blankets all clutter your pack, and they limit how freely you can move.

Damp British Chill & Lost Insulation

Morning condensation and damp ground in the UK seep through cheap bag fabrics, wearing down insulation and leading to restless, broken nights.

of British campers say their sleep is disturbed by freezing draughts around the feet and sleeping bag temperature ratings that fall short.

Relied On byThousands of Outdoor ExplorersThroughout the UK

"I brought the EmberLinie winter version on a wild camping trip near Glen Nevis, in -4°C weather. With my 10,000mAh Anker power bank plugged in and the setting on medium, I was asleep within minutes. The dedicated heat pads at my feet were a real game changer."

"Autumn campervanning in the Lake District is our thing. My partner and I joined two EmberLinie bags into one huge heated double quilt. The draughts vanished entirely, and we stayed toasty all night without putting the van heater on."

"As a carp angler I often fish through the night in the Peak District. Its 210T ripstop shell held off early morning frost and bivvy moisture, so the inside stayed dry. A gentle wash cycle freshened it up like new afterwards. Money well spent."

CommonQuestions

Here are answers on how long the heat lasts, which power banks work, how to look after the bag, and what the winter version offers.

What powers the EmberLinie Heated Sleeping Bag?

EmberLinie runs from any standard 5V/2A USB power bank (power bank not included). Connect the power bank to the built-in interior USB cable, tuck it into the secure internal pocket, then press the power button to begin heating.

How long does the heating run on one charge?

Using a standard 10,000mAh power bank, you should get about 7 hours of non-stop warmth on the low setting (approx. 40°C), 4.5 hours on medium (approx. 48°C), and 3 hours on high (approx. 55°C). Switching to a 20,000mAh power bank doubles your runtime.

Is EmberLinie washable in a machine?

Yes. Its carbon heating elements and wiring are completely sealed and waterproof. Unplug and take out your power bank, then wash the bag in the machine on a gentle 30°C cycle. Let it air-dry fully before using it again.

Which temperature ratings can I choose?

You can choose between a 3-season and a winter specification of EmberLinie. Comfort rating on the 3-season edition reaches down to -5°C, whereas the heavyweight winter edition gives reliable thermal protection to -15°C. Both suit wild camping in frosty UK autumns and winters.

Can it open out flat like a duvet or join up as a double?

Yes! Unzip the bag fully along each side and the foot box, and it lies flat as a spacious heated quilt for use in campervans, tents or beside garden firepits. Two compatible EmberLinie bags can also be zipped together, forming a cosy double heated sleeping bag.

How do returns work for UK orders?

All UK orders are covered by a 30-day money-back guarantee. If the warmth, comfort and build quality do not completely delight you, just return it in its original condition and our UK support team will handle a fast, hassle-free refund.

How small does EmberLinie pack down in its compression sack?

It packs into the supplied heavy-duty compression sack at approximately Φ24 × 38cm, weighing from 1.8kg depending on which weight version you pick. It clips easily onto hiking rucksacks or fits tidily in car boots and campervans.
