I was about to buy the Sea to Summit XT Ether insulated but they are £150 for the regular size. I wanted the wider version which is 60cm wide I think. These cost even more and difficult to find. I then realised I might only use this for car camping or in friends barn etc. So it doesn't have to be ultralight. I see Outwell do a 10cm thick model and I think Vango do one for about £32. I had a sea to summit ultralight version 5cm thick and liked it but can't find it... Any recommendations for something a little more robust than my Exped Synmat UL7 which is comfy but delaminated?
