Sack Size 14cm tall * 7 cm diameter [5½" * 2¾"]
weight 125g [~4.5 oz]
The dimensions are rated at:
Length 185cm [6' 1"]
Width at head 92cm [3' 0"]
Width at foot 62 cm [2' 0"]
However my rough measurements came to:
Length 180cm [5' 10"]
width at head 89cm [2' 11"]
width at foot 58cm [1' 11"]
Unlike most 'mummy' bags and liners, this liner actually maintins its width until the hips (80cm) and only narrows to the foot after that (over the last 100cm).
At 182cm tall I was worried that this might not be quite long enough, I was pleased to discover that it's still OK for me; however if I was much taller I'd want the 'long version' that "Sea to Summit" do (although 'long' is only available in rectangular, not in the mummy shape).
The silk liner is so thin you can see daylight through it and as a result I was expecting to find that it wasn't as warm as my fleece liner. I was pleasantly surprised to discover that this is *not* the case. Sea to Summit claim "Adds up to 10 degrees of warmth" (unclear if that's °C or °F) and I certainly felt it was adding warmth to my bag at least as much as my much bulkier fleece liner does.
The manufacturer (Sea to Summit) describes the colour I received as "Eucalyptus" (a pleasant dark green), however the manufacturer also makes 5 other colours so no guarantees what colour you might get from this distributor.
Although the liner is defined as "Machine washable" it's marked as 20°C. Most washing machines don't go below 30°C so I consider it handwash only. However thats not a big imposition as it's easy to wash and drys very quickly. I think there is a good chance you could wash it first thing in the morning and it would be dry enough to use that night (unlike my fleece sleeping bag liner which takes three or four days to dry out).
Even crumpled the liner stuffs back into the sack easily.
Overall I'm very pleased with this liner.
