We’ve got a small collection of self-inflating mats. For light weight camping a couple of Thermarests and a couple of cheaper brand imitations, for car and big tent camps we’ve also got a couple of big Outwell mats.
Setting up the big tent at the start of a Tandem Rally last week I realised that the big thick double Outwell mat has failed, could be a small pin hole, or more likely a failed seem maybe. It has occurred to me since that over the past half dozen years we’ve had 3 mats fail in this way, all of them big thick Outwell’s, (the other two were singles however).
I’m wondering now whether it’s the increased depth that makes them more prone to failure or whether Outwell mats are just a bit naff?
Has anyone had any success in repairing self-inflating mats? They all have very slow leaks that are going to be very hard to detect.
