It is in Lidls from next Monday, I will pop in then and try holding one if they are in the Dalkeith shop.
I will be surprised if they are as light as 2 Thermarests put together.
UPDATE
I went to Lidls today (21 June) and the mats are in.
They are very bulky and look like a 3 man tent rolled up, I picked one up and would estimate the weight at around 3 Kgs. There was no weight printed on the packaging that I could see.
