Before I go and waste $40, a bunch of time and fill my house with feathers I thought I'd get some input from those who may know a bit more than me.
I've had an Exped Downmat 7 sitting in the shed for a while suffering from the standard baffle blow out.
I've searched all over the internet and can't find a way to repair this myself. Recently I saw a $40 inflatable mat online. I'm sure you have all seen the sort I'm talking about, they are uninsulated and a dime a dozen on all the standard online auction sites.
So, can I buy a cheap mat, cut the very end off, fill it with the 700loft down from the exped and then reseal the cheap mat with an iron?
I'd also need to figure out how to jam a piece of open cell foam or similar into the valve.
Before I go on a stupid diy mission can anyone see any faults in this plan. My only concern is that the cheap mats won't reseal and are welded using a process not repeatable with an iron.
