Our ratings (out of 10)

1 to 10, compared with the whole market. Each says what it's based on. How we score

Warmth

From maker's figures 6/10

How cold a night you can sleep comfortably through. 6: A bit better than average.

Exped says its sleeping bags are tested in a certified lab to ISO 23537-1 (FAQ on the Ultra -5C 20F page of its global site; the UK page gives the figures but not the standard). The comfort figure of 1 °C sits in the 0.1 to 5 °C band; the limit is -4 °C and the extreme figure -21 °C.

Room inside

Estimate from maker's specs: maker's shoulder girth (fewer than 3 reviews about room) 3/10

How much room to move, bend your knees and sleep on your side. Roomier is comfier. 3: Below average. Fine for some trips, not others.

No review we found says how roomy it is, so this is an estimate from the maker's shoulder girth.

Weight

From maker's figures 7/10

How much it adds to your pack. 7: Better than most.

870 g (size M, Exped figure) sits in the 700–999 g band. One UK shop lists 840 g; the Exped figure is used.

Packed size

From maker's figures 5/10

How much room it takes in your rucksack. 5: Does the job. Average for wild-camping gear.

Exped's own packed volume for size M is 8.2 L (17 x 22 x 22 cm), in the 6–8.9 L band.

In short

Good for

  • Weight-conscious three-season camps in the UK, from spring to well into autumn
  • Backpackers who want a mummy bag with a roomy 3D footbox and a draft collar
  • Anyone who wants a light down bag with a roomy footbox for three-season camping

Strengths

  • 870 g and 8.2 L packed in size M, with an ISO 23537-1 comfort figure of 1 °C and limit of -4 °C
  • 850+ cuin RDS-certified musk duck down, 500 g of fill in size M
  • Adjustable elliptical thermal collar, 3D footbox and a cover strip along the zip to cut cold bridges
  • Anti-snag zip with a large zip garage, inside pocket and a roll-top drybag included
  • Made in five sizes (S, M, MW, L, LW), so the fit can be matched to the sleeper

Weaknesses

  • Comfort 1 °C and limit -4 °C are warmer than the -5 in the name suggests, so treat it as a limit-rated bag
  • New for 2026, so no independent hands-on test of this exact bag found: the damp, comfort and durability scores are 'Not enough evidence'
  • Exped's global page says it is available in Switzerland, Germany and Austria from 2027, while Exped UK and one UK retailer already list it
  • Size M fits users up to 180 cm only
