In reply to JStearn:
Don’t get a Sea to summit with the poker dot weld pattern, after a while (year or two) the fabric pin hole punctures where it creases into the dot. I have multiple punctures due to this and now can’t get more than a couple of nights before it suffers another hole with exactly the same failure mode.
I emailed sea to summit about this and didn’t even get a courtesy reply.
Sadly I’ve just bought an Xtherm as a replacement……
As well as inflating by breath did you store rolled up or loose?
