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 7/10

How cold a night you can sleep comfortably through. 7: Better than most.

Maker's EN 13537 comfort -2 °C (limit -4 °C) sits in the -4.9 to 0 °C band. Alpkit's own 'AK Sleep Limit' of -7 °C is not a standard rating, so it isn't banded.

Room inside

Estimate from maker's specs: bag shape (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 bag shape.

Weight

From maker's figures 6/10

How much it adds to your pack. 6: A bit better than average.

1,140 g for the Regular bag (the 115 g stuff bag is extra) sits in the 1,000–1,299 g band.

Packed size

From maker's figures 1/10

How much room it takes in your rucksack. 1: A real weak point.

Maker gives 24 cm diameter x 35 cm for the stuff sack: 3.1416 x 12 x 12 x 35 = 15,834 cm³, so 15.8 L, in the 13 L+ band.

In short

Good for

  • Car-based and bothy trips, and people who want a roomy bag with a comfort rating below freezing

Strengths

  • 700 g of down in box-wall baffles with trapezoid side baffles to limit cold spots
  • Roomy cut: 75 cm internal width and 185 cm internal length (Regular)
  • Includes a compression stuff bag and a cotton storage bag, covered by a 3 year Alpine Bond

Weaknesses

  • 1,140 g and 15.8 L packed: heavier and bulkier than most rivals with a similar rating
  • 650 fill power duck down in 20D polyester, so it is not a lightweight-trip bag
  • The brand's own AK Sleep Limit of -7 °C is more optimistic than the -4 °C EN 13537 limit; use the EN figures
  • Regular is 185 cm inside, so people near 180 cm tall should look at the Long
  • No independent hands-on review of the current bag found, so damp, comfort and durability scores are Not enough evidence
