/ thermarest problem
not myself, but have known one who has.
thermarest is well known for its lifetime guarantee, so dont hesitate to go straight to them.
as it goes, i have one thats 15 years old and hasnt bubbled, so somethings up. send photos etc to make it clear, but may take time if it has to go to the top in the US.
yes. Send 'em back. They'll replace them no problems.
Just had this happen with mine, sent it back and a new one is on the way!
Did you leave it in the sun/somewhere hot with it inflated by any chance? I had this problem as we left them in the back of the car with the sun on them.
Hopefully they will honour their guarantee.
Initially you should return these to place of purchase, if that is not possible, then contact The UK agents, Pro Agencies Ltd. this has recently changed so I don't know how they are handling returns
