Just got a call from MontBell yesterday and I went to the head store to pick up the mat (90 cm, short version). They had told me on the phone that they weren’t able to fix the mat and so were giving me a new one. Now this left me quite concerned so I discussed the problem with the store clerks (one of whom was very knowledgeable and was able to answer all technical questions on the spot).
There had been two problems with the original mat: 1) a slow leak somewhere around the vulcanized patch I put on after I found the pinhole by immersing the mat under water in the bathtub. Three times I had fully inflated and left the mat standing in the corner of my room to determine if there really was a slow leak. Each time the mat was flat the following day, whereas my Torsolite has been standing inflated since the end of October and is still as tight as ever. 2) Two small penny-sized blisters under the skin of the mat developed after a summer of use and were slowly growing every time I inflated the mat.
It seems that the leak provided no problems for repair and the old mat would have been returned, but there was nothing MontBell could do about the blisters and that is why they decided to give me a new mat.
That still left me concerned about what would happen if I was out in the field and another puncture developed that, again, I would not be able to fix with the provided patches and cement. They seemed unable to answer that and so all I can do now is get out into the field again with the new mat and see how it performs. I trust MontBell’s attention to detail and their field testing before selling a product. I’ve been using MontBell gear since 1977, two years after the store was established, and never once before has a single piece of their gear let me down (my only complaint is with their zippers and the accompanying stormflaps, on nearly all their gear) and I have a lot of their gear. I’d be surprised if the new pad presents problems again.
I just bought a pair of the Breeze Dry-tec cycling rain pants for riding to work and a pair of goretex rain shorts from their bargain bin in their outlet store. I’m hoping the rain shorts, since I rarely wear rain pants in the summer (I always wear a pair of Mammut Schoeller Courmayeur pants, usually rolled up to the knees), but don’t like sitting down and getting my bottom and crotch wet, will solve the problem of walking in the rain without rain pants (my real desire is to find or make a just-below-the-knee length cagoule made of eVent, from the style so popular back in the 70’s and 80’s but which are almost impossible to find now… blousy at the bottom hems, like a poncho, with wide arms, that I can pull over my knees when sitting in the rain. MontBell makes a very good rain cagoule, but it is too narrow to pull over my knees when I squat down).
I’ll let you know how the new mat fares after a few months of field use.
