Our ratings (out of 10)
1 to 10, compared with the whole market. Each says what it's based on. How we score
Warmth
Estimate from maker's specs: maker's own comfort rating, not lab tested (one band lower) 7/10How cold a night you can sleep comfortably through. 7: Better than most.
Estimate from maker's specs
Room inside
Estimate from maker's specs: bag shape (fewer than 3 reviews about room) 3/10How 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 1/10How much it adds to your pack. 1: A real weak point.
2,100 g is in the 1,700 g+ band.
Packed size
From maker's figures 1/10How much room it takes in your rucksack. 1: A real weak point.
Maker gives 30 cm x 26 cm (length x diameter, our reading), so a stuff sack: 3.1416 x 13 x 13 x 30 = 15,928 cm³, so 15.9 L, in the 13 L+ band. The other way round it is 18.4 L, the same band.
What reviewers say (out of 10)
Ratings marked * are from reviews and are not part of the trip score. They are reviewers' scores, not our own measurements. How we score
Comfort to sleep in*
Estimate: only 1 review about comfort to sleep in (fewer than the 3 we need, so never above 8) 8/10How comfy the shape, hood and fabric feel; not the temperature rating.
1 review on comfort to sleep in, e.g. "it was luxury compared to anything I've used in the past".
Zip*
Estimate: only 1 review about zip (fewer than the 3 we need, so never above 8) 6/10How smoothly the zip runs without snagging.
1 review on zip, e.g. "I had some trouble zipping it all the way up around the head, the zip kept sticking.".
In short
Good for
- Car camping and general camping where a vehicle carries the bag
Strengths
- Synthetic fill, so it is easier to care for and less fussy about damp than down
- Insulated shoulder baffle and a baffle behind the two-way side zip
- Soft polyester lining and a compression sack in the box
Weaknesses
- Heavy at 2,100 g and large at about 16 L packed, so not for carrying far
- Its -7 °C comfort and -12 °C low figures are not from an ISO 23537 or EN 13537 test (Snugpak says they are guidance only), so we can't score warmth
- No independent hands-on reviews found, so comfort, damp and durability are estimates, not reviewed scores
- Made abroad (the maker says imported), unlike Snugpak's UK-made Softie range
