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 5/10How well it stops the cold ground chilling you. 5: Does the job. Average for wild-camping gear.
Sea to Summit's ASTM-tested R-value of 3.0 is in the R 3–3.9 band: spring and autumn, not winter.
Thickness
From maker's figures 5/10How deep it is. Deeper is comfier, above all for side sleepers. 5: Does the job. Average for wild-camping gear.
5 cm thick.
Quietness
Estimate from maker's specs: mat type (fewer than 3 reviews about noise) 7/10How little it crinkles or squeaks when you turn over. 7: Better than most.
No review we found says how noisy it is, so this is an estimate from the mat type.
Weight
From maker's figures 6/10How much it adds to your pack. 6: A bit better than average.
Sea to Summit's 605 g for the Regular Contour is in the 550–749 g band (630 g with the stuff sack; shops list 583–599 g).
Packed size
From maker's figures 4/10How much room it takes in or on your rucksack. 4: A bit below average.
Packs to 29 x 14 x 14 cm, a roll: 3.1416 x 7 x 7 x 29 = 4,464 cm³, so 4.5 L, in the 4–6.9 L band.
In short
Good for
- Spring to autumn wild camps for side sleepers who want a quiet, mattress-like mat
- Hikers who prefer self-inflating foam-and-air construction to a fully air-filled mat
- Car-and-backpack use where a few hundred grams matters less than comfort
Strengths
- R 3.0 (ASTM F3340) in a 5 cm thick mat
- Contour shape is 56 cm wide, with extra room at the shoulders for rolling over
- Quiet: GearJunkie called it nearly silent
- Foam core partly fills the mat by itself; one valve inflates, deflates and fine-tunes
- Repair kit and side-loading stuff sack included; 20D recycled fabric
Weaknesses
- 605 g and about 4.5 L packed: heavy and bulky next to air mats of the same warmth
- Self-inflation only reaches about 65–75% (GearJunkie needed five breaths after an hour), so you still blow it up
- R 3.0 is only just enough for spring and autumn nights
- Only one detailed independent review found, so comfort and durability are estimates, not reviewed scores
- Shops quote 583–605 g for the same mat
